The research demonstrated that treatment of eggplant of Diamond variety with 1-NAA, GA3 and 6-BAP growth stimulators affect the growth and quantitative indices of the leaf apparatus. The study proved that GA3 increased the height plant by average of 16.3%. All drugs increased the number of plant leaves, the mass of their wet matter and the area of the leaf surface. GA3 turned out to be the most powerful. The study showed that during the growing season there was an outflow of sugars, mainly due to reducing forms from the vegetative organs to the fruits in the experiment as well as in the control. It was investigated that the content of starch grew in roots during vegetation, in fruits in the first part of vegetation and declined in stems and leaves. Growth stimulators contributed to the accumulation of assimilates in vegetative organs in the first half of the growing season and increased their outflow to the fruits in the second half of the vegetation. All drugs increased the accumulation of sugars and starch in the fruits during the growing season. Such changes in the processes of accumulation and redistribution of carbohydrates have contributed to crop yields. |
