Laboratory of subtropical plants

Objectives
  • Research on problems relevant to adaptation in the environment, growth and development, cultivation techniques and propagation of some tropical and subtropical fruit plants which appear to be economically important for Greece like: Avocado, Mango, Loquat, Papaya, Jojoba, Carob, Cherimoya, Date Palm, Pecan, Litchi, Persimmon, Cactus Pear, Pomegranate.
  • Study and evaluation of the rootstocks concerning their adaptation and resistance to different diseases.
  • Production and conservation of healthy genetic material of citrus.
  • Propagation of plants by applying either conventional techniques (seedlings, grafting, rooting cuttings) or biotechnological methods (in vitro culture of tissues or organs
  • Study of soil ecosystem and plant microbe interactions as well as their significance for sustainable agriculture
  • Surveys for CTV virus of citrus plants

Results
  • Were evaluated the new late navel orange varieties "Navel Late" and "Lane Late" as well as the super early clone of navel orange "RO 25" that is a choice of Institute of Olive tree and Subtropical plants of Chania.
  • Varieties of 'Bergamot' (collection of Institute)
  • Evaluation of the recommended cultivars 'Marisol', 'Nova', 'Clasuelina' and 'Miyagava wase'. The cultivars 'Marisol' and 'Miyagava wase' reach maturity in October while the hybrid 'Nova' allows picking in November and sustains its outstanding characteristics very well, until February.
  • New rootstocks were studied and some of them were singled out for their good performance under the conditions of Crete. The rootstocks of Sour oranges (varieties Brazilian and Bittersweet) are tolerant to saline soils. The rootstock citrange 'Carrizo' is ideal for early varieties, and the citrumelo 'Swingle' for the late varieties.
  • At the installations of the Institute indexing for virus control was carried out. The disease 'exocortis' is the most common one. So that, for the reconstitution of citrus, the varieties to be used in future programs is necessary to use rootstocks tolerant to the viroid 'exocortis'.
  •  Certified propagative material of various tropical and subtropical fruit crops was imported, from research Institutes of other counties, and the possibility of their successful cultivation in Greece was studied. Evaluation and selection of the most important cultivars of Avocado, Kiwi, Banana, Mango, Cherimoya, Pecan, Feijoa, Date Palm and Cactus pear, for commercial cultivation, was carried out.
  • Propagative material of Avocado, Kiwi and Banana was produced and distributed to farmers in the framework of development programs of the Ministry of Agriculture.
  • Improvement in the propagation technique of Kiwi (rooting cuttings, tissue culture), of Avocado (grafting, tissue culture), of Cherimoya (rooting cuttings, tissue culture) and of Banana - Pistachio - Olive - Rubus (by tissue culture) was achieved.
  • Modern cultivation techniques on plantation systems, on plant size and structure, on pruning and on fruit thinning for the fruit quality improvement of the plants Kiwi, Avocado, Banana, Mango, Cherimoya, Pecan, Feijoa, Loquat and Cactus pear were applied and evaluated.
  • Cultivation techniques for the production of out of season Mango fruits by intensive cultivation under greenhouse were developed.
  • The harvesting indexes for Avocado and Kiwi fruits as they were affected by the crop location were determined
