Reproduction, Agrotechnics and Protection of Jacaranda mimosifolia D. Don (Jacaranda Juss.) in Absheron Conditions

In research work have been extensively studied morphological aspects of seedlings on a scientific basis, propogation by seeds and cutting methods on the Absheron Peninsula species of Jacaranda mimosifolia belonging to the genus of Jacaranda Juss. of the family Bignoniaceae. The research analyzed the sowing period of seeds, soil characteristics, sowing depth, initial germination period, morphological features, agrotechnics, disease and pest control measures. Studies have shown that Jacaranda mimosifolia has the ability to adapt to open and greenhouse conditions in Absheron — In the autumn began to appear the first seedlings in the first decade of October from the seeds sown in the second decade of September in a greenhouse condition, were obtained 4.6% of seedlings at the end of the growing season. In the spring began to appear the first seedlings in the third decade of April from the seeds sown in the first decade of April, were obtained 5.2% of seedlings at the end of the growing season. In the second decade of May, 20–30 cm tall plants were transplanted to open fields. At the end of the growing season the length of the compound leaves of annual plants reached 14×15 cm. Plant height reached 1.2 m in height, 1.2–1.5 mm in diameter, stalks reached 16 cm in length, 0.2 cm in width. There are 20 leaf-stalks on 1 leaf. Keeping the temperature in the greenhouse at 22–24 °C from April to the second decade of October had a positive effect on plant productivity. As a result of the research, it was found that in Absheron conditions the plant shed their leaves in the greenhouse at a temperature below 14 °C. As a result of the research, it was found that Jacaranda mimosifolia has the ability to adapt to open and greenhouse conditions in Absheron, it is profitable to use such an ornamental plant in the construction of parks and gardens, in decoration of offices and interiors.
