POSSIBILITIES OF USING GROWTH REGULATORS FOR FORMATION OF FRUIT PLANTS YIELD
06.00.00 Agricultural sciences
Description
The researches were about availability of the appliance of some physiology active matters – aminoethoxyvinylglycine (AVG) and melafen for optimization of yield formation for orange and apple trees. Field researches were conducted in 2011-2012 in commercial orchards in the region of Gingin in the Western Australia (climate of the region – Mediterranean, the soil – sandy) and in 2015-2016 in apple orchards of the botanical garden of Kuban State Agrarian University (climate of the region - moderately continental), started in 2006. The article shows expediency of using inhibitor biosynthesis of ethylene of AVG at a concentration from 20 to 60 mg /l when the orange fruit size was 3.0 cm, and the growth regulator "Melaphen" (concentration 1˟10- 9 М) in the second half of the vegetation period of apple plants (for 45-50 days before harvest). The use of treatments in these terms reduces pre-harvest fruit drop and thus increase the economic productivity of fruit trees (apple in - up to 11%). It is noted that a variety of orange called Washington Navel is more responsive to the increased concentration of AVG, than the variety of Lane Late (optimal concentration of 60 and 20 mg / l, respectively). We have shown a wide spectrum of action of the treatment "Melaphen" on apple plants. Along with the retention of the fruit on the tree, it enhances the activity of plant growths in summer and some weakening concerning tabs flower buds as well as the displacement of their development. However, the use of melaphen in this period increases the efficiency of the formation of various parts of flowers and fertilization in the next season. With such results of the adjustment processes of vegetative growth and generative development of plants under the influence of physiologically active substances, it will ensure the formation of relatively high and regular yields of fruits
