“…Changes in the reserves use in germinating seed are determined by the growth centers demand, and the processes of organogenesis, which are the main sink of these substances during heterotrophic development. It is established that the use of antigibberellin GR (retardants) leads to inhibition of linear growth and changes in morpho -and histogenesis of plants [24][25][26]. In particular, structural changes in the anatomy of the tobacco plants stem were detected both under the light influence and under the action of GA 3 .…”

The combination of light/dark external factor, GA 3 and GA 3 synthesis inhibitor tebuconazole significantly changed the pattern of the source-sink relationship in sprouts of horse bean during seed germination. The usage of gibberellin at light leads to increase of reserve starch hydrolysis in germinating horse bean seeds. The absence of light was a more significant factor for the starch hydrolysis than the exogenous use of gibberellin and the antigibberellin substance tebuconazole. The nitrogen-containing compounds content and reserve fats at early stages of germination in cotyledons did not change significantly, indicating less intensive use of these compounds for morphogenesis during this period. Seed germination was accompanied by a decrease under the action of gibberellin at light, and under the action of tebuconazole -an increase, in root and epicotyl diameter due to the peculiarities of histogenesis. Under the influence of gibberellic acid, total epiblem and the primary root cortex thickened at light, and the epidermis and the primary cortex of hypocotyl -at light and dark. The opposite change was caused by tebuconazole -the increase of tissue complex thickness occurred under both photoand scotomorphogenesis conditions. The number of xylem vessels in the vascularfibrous bunches in roots increased under the influence of tebuconazole in dark. In epicotyls, the increase occurred in the number of vessels in bunches under the action of tebuconazole both at light and in dark. Insofar as histogenesis is controlled by phytohormones, established histological changes indicated a significant re-structuring of the entire hormonal complex of seedlings.

“…An opposite pattern is observed in the functioning of the donor-acceptor system due to the fruits formation and growth during the formation of powerful acceptor zone in plants. The number and area of the leaf increased, the leaf mesostructure organization is optimized, the net photosynthetic productivity increased, which lead to an increase in yield [39,90,161].…”

The monograph summarizes the results of the study of the effect of different groups of retardants on the morphogenesis, formation and functioning of the donor-acceptor system of plants in connection with productivity of agricultural crops. It is discussed the mesostructural features of leaves and the activity of photosynthetic processes under artificial inhibition of linear growth and different plant loads with fruits and seeds. The influence of retardants on the donor-acceptor relations at the heterotrophic phase of development in the conditions of skoto- and photomorphogenesis was investigated. Issues of hormonal regulation of plant morphogenesis, features of accumulation, temporary storage and distribution of assimilates and nutrients between acceptors – processes of vegetative growth and carpogenesis are considered under the influence of retardant with various mechanisms of action. The monograph is for plant physiologists, graduate students, students of higher education institutions.
