Horticulture Newsletter - January 2011

tomato slice

12 Jan 2011

Welcome to the first Newsletter of 2011. The recent holiday period has taken its toll on this edition and we are missing a main article and our usual Medicinal Plant of the Month. In their place we have a report from Alison Foster outlining the results of last autumn's tenth summit of the Convention on Biological Diversity and some recent news from our Associates. Normal service will be resumed in February.

In the meantime do not forget to book your place at our forthcoming events; Medicinal Plants: From Crop to Cure? on 29 March and Biofortified and Functional Food: A Healthy Future? on 19 May.

Nagoya Biodiversity Summit and the GSPC, October 2010

Nagoya Castle The Nagoya summit ended with the adoption of a historic agreement to halt the loss of biodiversity worldwide. A new ten year Strategic Plan of the Convention on Biological Diversity (Aichi Target) includes 20 headline targets organised under five strategic goals that address the underlying causes of biodiversity loss, reduce the pressures on biodiversity, safeguard biodiversity at all levels, enhance the benefits provided by biodiversity, and provide for capacity-building.

Also updated at the summit was the Global Strategy for Plant Conservation (GSPC). The new targets are aimed at the period 2011-2020. Although no individual target of the first GSPC was fully met, the strategy has been widely considered successful. The updated GSPC states as its vision 'Without plants there is no life. The functioning of the planet, and our survival, depends upon plants. The Strategy seeks to halt the continuing loss of plant diversity.' The 16 new and updated targets are designed to provide guidance for the setting of national plant targets. These 16 targets fall under five objectives:

  • Objective I: Plant diversity is well understood, documented and recognised
  • Objective II: Plant diversity is urgently and effectively conserved
  • Objective III: Plant diversity is used in a sustainable and equitable manner
  • Objective IV: Education and awareness about plant diversity, its role in sustainable livelihoods and importance to all life on Earth is promoted
  • Objective V: The capacities and public engagement necessary to implement the Strategy have been developed.

Within the Horticulture group of the SCI, we should bear in mind these 16 targets as we go about our daily work. Which of the targets and objectives apply to us? Whilst we cannot ignore any of them, maybe the following three targets are particularly relevant.

  • Target 6: At least 75 per cent of production lands in each sector managed sustainably, consistent with the conservation of plant diversity.
  • Target 10: Effective management plans in place to prevent new biological invasions and to manage important areas for plant diversity that are invaded.
  • Target 14: The importance of plant diversity and the need for its conservation incorporated into communication, education and public awareness programmes.

In addition to the adoption of these strategic plans, a new international protocol is to be implemented on access to and sharing of the benefits from the use of the genetic resources of the planet. It is now time to look forward to the coming decade and work together not only to halt the loss of biodiversity but to make sustainable use of the resources we still have available to us.

Plant of the Month

Manihot esculenta - Cassava, Euphorbiaceae
cassavaAlthough little eaten in Europe, Cassava (Photo right by Paphrag) is a widely grown tropical vegetable and one of the major sources of carbohydrate in the tropics especially Africa. It has a long history and as a result has accumulated many names throughout the world. The best known to Europeans are Cassava, Manioc and Tapioca while in its native home in central America it is known as Yuca. Although the first evidence of cultivation is by the Mayan people around 1,400 years ago there is indirect evidence that it could have been used by man for at least 6,500 years. Today it is grown and consumed throughout the tropics.

The plant is a perennial shrub which forms hard elongated tubers in the earth as storage organs and it is these that are eaten. These tubers contain twice as much starch as a potato. Like all members of the Euphorbiaceae, cassava stems and roots exude a milky sap when cut. This sap contains two cyanogenic glucoside toxins, linamarin and lotaustrain both of which readily produce hydrogen cyanide when decomposed by the enzyme linamarase which is present in the cell sap. The quantity of these toxins varies between 20mg/kg in 'sweet' varieties up to 1g/kg in 'bitter' varieties. While it would seem sensible to grow the sweet varieties, in fact bitter varieties are often favoured, as the bitterness protects the crops from being eaten by predators.

cyanogenics For this reason they cannot be eaten raw and the toxins must be removed by soaking, cooking or fermentation. Populations that depend on cassava are needless to say very well aware of this requirement and have also developed other uses for the crop. Like all carbohydrate crops the juice can be fermented into alcoholic beverage or sliced and roasted into 'chips'. The 'hay' is used as animal feed and experiments are being undertaken to develop its use as a basis for the production of bio-ethanol.

manihot esculentaBecause the roots (Photo right by David Monniaux) contain very little protein, cassava can lead to malnutrition if not complemented with protein-rich foods. Brazilians eat the cassava leaves, which are rich in protein, as an accompaniment to the tuber in order to prevent such deficiencies.

Astonishingly, people living in malarial regions wash their cassava less carefully, leaving poisonous linamarin in the cassava flour and allowing cyanide to accumulate in the bloodstream of those consuming it. Together with the protein deficiency caused by a diet overly reliant on cassava, this inhibits the development of malaria parasites. I think I'll stick to quinine etc.

Hope for honey bees
honey bees Scientists may be able to halt global honey bee losses by forcing the deadly Varroa mite, the biggest killer of honey bees world-wide, to self-destruct. Researchers from the UK Government's National Bee Unit and Aberdeen University have worked out how to 'silence' natural functions in the mites' genes to make them self destruct. Dr Alan Bowman from the University of Aberdeen said, 'Introducing harmless genetic material encourages the mites' own immune response to prevent their genes from expressing natural functions. This could make them self destruct.' More (Picture by Suat Eman, Freedigitalphotos)

End of an Era
The last major UK chrysanthemum grower, Donaldsons is understood to have sold its site to berry grower Hall Hunter Partnership who will convert it to strawberry production. Simon Davenport Treasurer of the British Protected Ornamentals Association said, 'South Africa and the Dutch have taken a lot of the market. Many UK businesses simply got old and closed down because of economic pressures and fuel costs. No UK grower can supply in any quantity any more. Most are looking at supplying local markets instead'.

Meanwhile, 'seismic shifts' in the horticultural industry are ushering in opportunities through the 'great expansion of the grape, soft fruit and garden plant businesses,' added Colin Frampton, although this new period is witnessing some local industries 'passing away'. (FPJ, 17 Dec 2010) More and More

EMR research to help strawberry industry
Following two years of commercial trials managed by Sarah Troop and Meiosis Ltd, six varieties have been released and approved by UK supermarkets. The varieties include the June bearers, Elegance, Fenella, Cupid, Sweetheart and EM1119, together with the everbearer, Finesse. These varieties carry no exclusive licence arrangements and so are available for all growers to use. They provide a season-long range of alternative varieties that are said to incorporate excellent fruit quality and significant yield advantages with improved resistance to soil-borne diseases like Verticillium (South East Farmer, December 2010).

Help from Lavender
Scientists at East Malling Research are trying to find alternative ways to combat soil-borne disease, Verticillium dahlia, following the banning of the use of methyl bromide. An alternative approach involved biofumigation using plant-derived volatile chemicals to control soil-borne diseases. The scientists will use natural chemicals derived from lavender and brassica crops to suppress the fungus. This will involve the use of micro encapsulation technology developed by Essex-based Eden Research. These natural chemicals are less toxic to the environment. (South East Farmer, December 2010).

Applications sought
An industry partnership is to offer a new programme of science fellowships. The East Malling Trust (EMT), Horticultural Development Company (HDC) and the Horticultural Trades Association (HTA) have collaboratively developed the Horticultural Development Awards. Applications from scientific research institutions and universities are now being sought. It is envisaged that around five individual fellowships will be awarded, each worth up to £50,000 per annum and available for up to five years, starting from 1 April. The new fellowships are consistent with the findings of the Taylor Review, published earlier this year (FPJ, 17 December 2010).

Crop protection saves UK consumers £70bn
As spiralling development costs and restrictive new legislation threaten EU farmers' access to vital pesticide products, a new economic impact report by leading economist Sean Rickard of Cranfield University examines the true value of crop protection to the food chain and living standards. He concludes that without pesticides to keep weeds, pests and diseases in check, crop yields would fall to half their current levels and food prices would rise by 40%, an increase to UK consumers of some £70 billion per year in food costs.

Rabbits most costly invasive species
rabbit Britain's estimated 40m rabbits cost the economy more than £260m a year including damage to crops, businesses and infrastructure, a report says today. Their near 2,000-year survival as a non-native species makes them the costliest natural invader, according to research for the English, Scottish and Welsh governments by CABI, the international agriculture and environment organisation. The report also provides justification for the high costs of controlling non-natives. Richard Benyon, minister for the natural environment said, ''It becomes increasingly difficult and costly to control invasive non-native species as they become more established. Taking early action may seem expensive, but this report shows that it is the most effective approach, saving money in the long run and helping our native wildlife to thrive.'

Evolution of potato blight pathogen traced
Researchers have traced the key genetic changes that enabled the plant pathogen responsible for the 1845 Irish potato famine (Phytophthora infestans) to jump from wild plant hosts to cultivated potatoes. These genetic clues could aid the development of fungicides and disease-resistant varieties of potato that the pathogen will find much more difficult to adapt to and overcome. The researchers identified the key genes by comparing the genetic make-up of the potato blight pathogen and several of its sister species. To do so, they sequenced the genomes of four of the potato blight's sister species, including Phytophthora phaseoli, which infects lima beans (Phaseolus lunatus). They computationally analysed and compared these genomes with the genome of the previously sequenced P. infestans. More

Race against climate change
A global search to save the wild relatives of wheat, rice, potato and other food crops from climate change has been launched. The Global Crop Diversity Trust (GCDT) said the campaign was designed protect global food supplies against changes in climate and strengthen international food security. Norway pledged 50 million US dollars (£31.8m) to the effort, which will look for 23 food species including barley, lentils, chickpeas and beans, and is being supported by Britain's Royal Botanic Gardens based in Kew, Surrey.

The Global Professional section of the company markets professional products to commercial growers and those involved in ornamentals, turf, parks and green spaces and speciality agriculture all over the world. Scotts US professional seed business is not included in the offer. More

Plants 'remember' winter to flower in spring
snowdrop Scientists have now discovered that a long, non-coding RNA molecule, named COLDAIR, is required for plants to 'remember' they've gone through a long enough period of cold. In the autumn a gene called FLC actively represses floral production. After a plant has been exposed to 20 days of near-freezing temperatures, the scientists found that COLDAIR becomes active. It silences the FLC gene, a process that is completed after about 30 to 40 days of cold. With the FLC silenced as temperatures warm in the spring, other genes are activated that initiate blooming. COLDAIR helps to create a cellular memory for a plant, letting it know it has been through 30 or more days of cold. More (Picture by Tom Curtis, Freedigitalphotos)

New fungal biopesticides
Two new biopesticides, both based on naturally-occuring fungi, will be available from horticultural supplier Fargro in the new year. The first, Prestop, is based on the fungus Gliocladium cantenulatum and can be used on a range of vegetable, salad and herb crops as well as ornamentals. It is suited to tackling foliar and root diseases including Botrytis, Phythium and Fusarium. Prestop can be applied using a foliar spray, through drip irrigation, or as a growing media treatment. Trials on tomatoes showed very little Botrytis on the treated plot.

The second product, currently nameless, until it is officially registered by the Chemicals Regulation Directorate contains the fungus Metarhizium anisopliae, which is used to control vine weevil. It can also be used to control other pests, such as Western flower thrips. More
