Horticulture Group Newsletter June 2015
1 Jun 2015
May is the time to announce the winners of the David Miller Travel Bursary Award. This year we had twenty applicants and the panel had its usual task of narrowing this down to select the two winners. This year's winners are:
Benjamin Langendorf from the Department of Biology, University of York. Benjamin is studying the 'Pre-colonisation of strawberry planting materials with arbuscular mycorrhizal fungi to improve transplant growth and tolerance to soil-borne pathogens' and plans to use his award to attend the International Conference on Mycorrhiza at the Northern Arizona University in Flagstaff, USA
Idowu Joseph Rotifa from the University of Edinburgh and the Scottish Rural College. Idowu is working on an HDC funded project on 'Novel approaches for the management of leaf and bud nematodes in hardy nursery stock'. He plans to use his award to help fund a study visit to the USA visiting nematode specialists in Ohio, North Carolina and Georgia.
Later in June we join the Professional Horticulture Group South West for a visit to some Bristol Gardens followed by a tour of the new Life Sciences building at the University. Details to follow.
On 9th July we will be visiting Canterbury to learn about the gardens of Christ Church University and then move on to Deal where we will be looking at soft fruit production on Edward Vinson's Sandbanks Nursery at Faversham.
Looking for a job? Cranfield University are seeking Senior Lecturers in Post-Harvest Science and Seed Science and Research Fellowes in Plant Metabolomics and Postharvest Bioscience.

The week before the May bank holiday sees the annual extravaganza that is the Chelsea Flower Show, a showcase for UK gardening skills. However, behind the glitz and glamour of the media hype, there is serious business to be done.
The Royal Horticultural Society first moved its premier flower show to the Royal Hospital site in 1905. Although the site is cramped and offers no scope for expansion the RHS has resisted calls to move to alternative locations so exhibitors have to put up with its limitations.
From a business point of view the advantages in terms of publicity and media coverage are all too apparent, not to mention the vast crowds of potential customers that the show pulls in. The disadvantage for the majority of horticultural companies is that no space is allocated to selling plants.
That does not mean that the show does not offer business opportunities, as a recent visit by the Horticulture Group in conjunction with the Professional Horticultural Group South West demonstrated. Hardy’s Cottage Garden Plants is located in the valley of the River Test, east of Whitchurch. Started by Rosy Hardy as a business selling vegetable plants at car boot sales, it now specialises in herbaceous perennials. Shows generate the majority of the company's sales so they have become a regular Chelsea exhibitor, this year winning their 20th coveted Gold Medal.
One of the key problems with Chelsea is timing. The show date can vary by as much as a week as the bank holiday moves – 2015 was about as early as it gets. Add to that the vagaries of the English weather and you have a challenge. To meet that, like most growers, Hardy’s propagate many more plants than they need and play a cat and mouse game with the weather moving plants to warmer or cooler locations to ensure that sufficient plants are at their best on the days of the show.
However, these are just ‘show’ plants which will demonstrate the range and quality that this nursery undoubtedly produces. They may elicit some orders but no-one can walk away from their stand with a new acquisition. At least not until the gong goes at the end of the final day and the previously sedate audience turns into a frenzied mob out to grab every ‘bargain’ they can.
As any visitor to the show or viewer of the TV coverage will know a major feature of the event is the show gardens. These are usually a collaboration between a sponsor who puts up the money and a designer. Neither usually has the capacity to prepare plants for the show and must rely on experienced nurseries like Hardy’s to get their plants ready for them, needless to say at a price. Rosy showed us some of the plants she is preparing for others, including such novelties as nettles, dandelions and cow parsley – for a wild-flower garden.
Space at Chelsea is very limited so by no means can everyone who wants to exhibit have a stand. A potential exhibitor usually has to exhibit at the regular RHS Westminster shows (where space is allowed to sell plants) and prove that you are capable of putting on a display of the quality the organisers demand. Once acquired you have a site which others less fortunate would like to take advantage of. Typically these will be the breeders of new varieties. Rosy thus enters into commercial deals to promote and market promising new varieties. She showed us Antirrhinum ‘Pretty in Pink’ which was one such new variety which she was putting forward on the breeders behalf for Plant of the Show. It was judged to be in the top twenty, however it failed to gain one of the top three spots. All is not lost for the variety however as Rosy has spotted that the variety could make a good cut-flower. If this proves to be the case, the royalties could more than compensate for the failure to achieve the top award.

Plants of the Month
Little and large – pink flowered Apiaceae
Chaerophyllum hirsutum ‘Roseum’, hairy chervil ‘Roseum’
A delicate pink flowered perennial umbellifer (picture right by Lazaregagnidze) to make a change from the typical white flowers so often exhibited by this family of plants. This cultivar elevates chervil to border-worthiness. The name derives from the Greek chairo meaning to please, rejoice and phyllon meaning a leaf. The specific epithet of course meaning hairy.
The foliage, as with common chervil, is aromatic, and very finely divided. There are 35 species in this genus, all from northern temperate regions, with 12 species originating in Europe.
Melanoselinum decipiens, Madeira giant black parsley
Another pink flowered umbellifer, though this time monocarpic and certainly not delicate. In fact it is a great example of a biological phenomenon known as Insular Gigantism. This is when an organism is isolated to an island and increases in size compared to its mainland relatives. The island in question for this species is Madeira. In its native habitat it is found in clearings in the laurel forest or in moist parts of the mountains (picture right by Maximovich Nikolay).
This evergreen plant grows for several years, before flowering and then dying, but in bloom it will be covered with umbels of pink tinged flowers. But beware – in the UK you will need a sheltered spot – it is borderline hardy as you might expect from a plant endemic to Madeira. Maybe this is what the specific epithet is referring to – decipiens meaning deceptive or cheating.
Medicinal Plant of the Month
Ammi visnaga, khella, Apiaceae
Ammi visnaga, a member of the carrot and parsley family native to Europe, Asia and North Africa, is just one of a large group of beautiful white umbellifers (picture upper right). But in this case, it also has some useful medicinal properties. This plant was known to the ancient Egyptians for its antispasmodic properties, and has been shown to produce a chemical compound called khellin. Between 1958 and 1966 a drug discovery programme was underway in Belgium using khellin as the inspiration. Scientists synthesised and tested a large number of potential drug molecules with structures similar to that of khellin until finally one was shown to be an effective coronary vasodilator. Compound L2329 (amplivix, benziodarone) now known as amiodarone was born. Today, amiodarone is prescribed to treat angina pectoris as well as arrhythmias. The next time someone asks you what Belgium is famous for – you have a new answer – amiodarone!
The dried flower stems (pedicels) of khella are sold in Egypt for use as toothpicks – hence another common name of toothpickweed. (Lower picture right by Michel Benoist)
(An aside on naming of drugs: Prior to a new drug being launched on the market it is given two names. One is known as the generic name and applies to the molecule that is the active drug substance however it is made, however it is formulated and whoever has manufactured it. The drug when formulated in a particular way and by a particular company is given another name – the proprietary or brand name. For example the drug substance amiodarone is formulated as tablets and an intra-venous infusion under the brand name Cordarone X by Sanofi-Aventis but under the generic name amiodarone by several other manufacturers.)

Supercomputer unlocks the mysteries of cellulose
Scientists have moved a step closer to identifying the nanostructure of cellulose - the basic structural component of plant cell walls. Tapping into IBM's supercomputing power, researchers have been able to model the structure and dynamics of cellulose at the molecular level. The research shows that within the cellulose structure, there are between 18 and 24 chains present within an elementary microfibril, much less than the 36 chains that had previously been assumed. These insights could pave the way for more disease resistant varieties of crops and increase the sustainability of the pulp, paper and fibre industry - one of the main uses of cellulose. More
The origin of the beefsteak tomato
A team of scientists has identified a set of genes that control stem cell production in tomato. Mutations in these genes explain the origin of mammoth beefsteak tomatoes. More important, the research suggests how breeders can fine-tune fruit size in potentially any fruit-bearing crop. In its original, wild form the tomato plant produces tiny, berry-sized fruits. Yet among the first tomatoes brought to Europe from Mexico by conquistador Hernan Cortez in the early 16th century were the huge beefsteaks. The secret of the beefsteak tomato has to do with the number of stem cells in the plant's growing tip or meristem. Specifically, the team traced an abnormal proliferation of stem cells to a naturally occurring mutation that arose hundreds of years ago in a gene called CLAVATA3. Selection for this rare mutant by plant cultivators is the reason we have beefsteak tomatoes today. More & More
APS Group acquires Wight Salads
The APS Group announced their successful acquisition of Wight Salads Ltd (part of Vitacress). The acquisition will create a business with a projected annual turnover of £100M, making them the largest grower and supplier of British tomatoes. Acquiring WSL has added 66 acres of glasshouses across 5 sites at Arreton on the Isle of Wight with onsite packing facilities, together with a site at Chichester in West Sussex which houses WSL’s head office function, including a 40,000 sq ft packhouse. The combined group will now total 265 acres with 108 acres of high tech glasshouses dedicated to producing tomatoes, resulting in the APS Group becoming the UK’s largest grower and supplier of British tomatoes providing a significant boost to the British tomato industry. Vitacress is part of the Portuguese RAR Group and their Portugese and Spanish nurseries are not included in the acquisition, but APS will be marketing the fruit from there as well. More
The Chinese approve
A new hybrid plant used in anti-malarial drug production, developed at the University of York’s Centre for Novel Agricultural Products (CNAP), is now registered as a new variety in China. Developed through CNAP’s Artemisia Research Project, the plant is believed to be the first instance of Chinese registration for an Artemisia annua variety bred outside China. Since China is the world’s largest grower of Artemisia, the plant can now contribute even more to the global production of the anti-malarial drug artemisinin. CNAP’s project used fast-track plant breeding to develop many new hybrids which then underwent rigorous field-trialling in Africa and Asia. A single robust F1 hybrid was selected for its excellent biomass features and ability to produce good concentrations of artemisinin in its leaves. More
New top fruit business formed…
Norman Collett, Fruit Growers Alliance (FGA) and the Society of Top Fruit Growers (SGT) are set to merge to form a fully integrated marketing and growing group. Avalon Produce Ltd (APL), as the new business will be known, is on course to start trading in July 2015, when existing retail programmes run by the respective businesses come to an end. APL will be 50 per cent owned by the SGT and FGA producer organisation grower groups, who will form half of the management board. More
… and a new breeding programme
Two berry breeders have pooled resources in a new programme to trial strawberry and raspberry varieties in the Netherlands. Scottish soft-fruit firm, Angus Soft Fruits, has partnered with Dutch company Genson BV on a new strategic raspberry and strawberry-breeding programme. The arrangement between the two companies will see new varieties from Angus Soft Fruit’s breeding programme trialled in the Netherlands. Selected varieties will then be used across all of northern and central Europe, excluding the UK. More
