Laboratory of subtropical plants



ObjectivesThe Institute for Olive tree, Subtropical Plants and Viticulture (IOSV), established in Chania, is the curator of the National collection of Subtropical plants.
The main research objectives of the lab of Subtropical plants & Tissue culture are:

• Ex situ conservation and enriching the national collections of the subtropical crops: avocado, prickle pear, loquat, mango, carob, banana, cherimoya, pecan, date palm, feijoa, guava, carambola, macadamia, litchi.
• Evaluation and study of subtropical crop varieties, referring to physiology and adaptation to new climate data.
• Production and evaluation of new varieties and rootstocks, aiming at early season production, fruit quality and resistant to biotic and abiotic stress.
• Conservation and production of healthy genetic material.
• Study and applying of conventional propagation techniques on subtropical and tropical species like seedlings, grafting etc.
• Study and applying of in vitro technique for plant propagation.
• Study and evaluation of pioneer compounds for their use in subtropical crops, in terms of yield and fruit quality and yield.

Results• A cultivation technique for the off season Mango fruit production was developed, by intensive cultivation in greenhouse.
• New cultivation techniques were applied and evaluated on plantation systems, plant size and structure, pruning and fruit thinning for the fruit quality improvement of the plants Avocado, Banana, Mango, Cherimoya, Pecan, Feijoa, Loquat and Prickly pear.
• Improvement of the propagation technique of Avocado (grafting, tissue culture), Cherimoya (rooting cuttings, tissue culture) and Banana - Rubus (by tissue culture) was achieved.
• Genetic material of Avocado and Banana was produced and distributed to farmers in the framework of development programs of the Ministry of Agriculture.
• Certified genetic 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, Banana, Mango, Cherimoya, Pecan, Feijoa, Date Palm, Loquat and Prickly pear, for commercial cultivation was carried out.
