“…It is known that plant productivity depends not only on the photosynthetic apparatus structural features, but also on its activity [37,38]. Our results of measurements of gas exchange rate in tomato leaves treated with growth regulators indicate that by the end of the flowering stage only 6-BAP significantly increased the net assimilation rate, and under the EW-250 influence there was a tendency to increase this index (Table 3).…”

There were studied the peculiarities of growth processes, the formation of the leaf apparatus, its mesostructure and photosynthetic activity, as well as the biological productivity of the Bobcat hybrid tomato plants under the influence of synthetic analogues of growth promoting hormones-1-naphthaleneacetic acid (1-NAA), gibberellic acid (GA 3), 6-benzylaminopurine (6-BAP), and retardantschloromequate chloride (ССС-750), tebuconazole (EW-250), ethephon (2chloroethylphosphonic acid, 2-CEPA), which differ in the action mechanism. It was revealed that growth promotors increased, and retardants reduced the tomato plants height. It was established that 1-NAA, GA 3 , and CCC-750 increased the leaf number on the plant, while under 2-CEPA treatment, the index was less than the control, and under the EW-250 action it remained practically unchanged. All growth regulators, except 2-CEPA, increased the leaf blades number, the fresh weight, and leaf area. All growth promotors increased the whole plant dry weight, while the retardants EW-250 and CCC-750 did not affect this index, and 2-CEPA significantly reduced it. All retardants and 6-BAP significantly increased the total chlorophyll content in tomato leaves, while under the action of GA 3 this index decreased. The retardants EW-250 and CCC-750, and the growth promotor 6-BAP contributed to the thickening of the tomato leaf chlorenchyma, and the ethylene producer 2-CEPA reduced it. Under the influence of all growth regulators, except 2-CEPA, the volume of columnar parenchyma cells increased. It was established that at the stage of fruit formation onset, all growth regulators, except 1-NAA, increased the rate of CO 2 assimilation, photorespiration, dark respiration and transpiration. All growth regulators, except 2-CEPA, contributed to the increase in tomatoes yield, while the use of the growth promotor 6-BAP and the retardant EW-250 proved to be the most effective.

“…Регуляція донорно-акцепторних відносин у рослині є найвищим рівнем в ієрархії процесів, що забезпечують її функціонування як цілісної системи [4]. Дослідження взаємодії фотосинтетичних і ростових процесів та їхніх зв'язків з біологічною продуктивністю основних сільськогосподарських культур є одним з головних завдань сучасної фізіології рослин [5].…”

The studies of plants’ assimilation activity of the Triticum carthlicum Nevski. (=Triticum persicum Vav.) tetraploid species’ variety samples have been carried out in the subtaiga zone (Aromashevo) and the northern forest-steppe zone (Tyumen). The number of leaves on plants by zones varied from three to five. Measurements showed that the lamina length varied from 6.4-23.7% in the northern forest-steppe zone and from 0 to 21.9% in Aromashevo. The lamina area on the main shoot of the Triticum carthlicum Nevski variety samples in the northern forest-steppe zone amounted to 62.3 cm2, which was 26 cm2 less than in the subtaiga zone. Calculation of net photosynthetic productivity in northern forest-steppe zone showed that Triticum carthlicum Nevski variety samples formed from 10.864g*m2/day to 20.764 g*m2/day, giving way to durum and soft wheat. In the subtaiga zone, PPn of Triticum carthlicum Nevski wheat varied from 9.088 to 13.827 g*m2/day, significantly yielding Bezenchukskaya 139 variety.
