Aim. Study of the effect of red (660 nm), green (530 nm) and blue (450 nm) light on the growth processes and the state of the antioxidant system in the axial organs of seedlings of pea plants. Methods. Etiolated seedlings of pea Maecenat variety were irradiated with selective light with different spectrum of RL (660 nm), GL (530 nm), BL (450 nm) to activate photoreceptor systems of plants. In 10-day-old seedlings, growth response was determined – linear growth and biomass accumulation, as well as indicators of antioxidant system – hydrogen peroxide content and activity of oxidases – catalase and nonspecific peroxidase in axial organs of seedlings: in the aboveground part and roots. Results. Irradiation of the RL and the GL stimulates the accumulation of seedling biomass in the aboveground part and roots. BL inhibits the growth response of seedlings. The maximum stimulating effect is shown by the GL. The state of the antioxidant system in etiolated seedlings is characterized by organ specificity. Under the action of selective light, the content of the main form of ROS – hydrogen peroxide and shoots and in the roots, significantly stimulates the activity of catalase and peroxidase enzymes in the aboveground part of the seedling and is inhibited in the roots. The maximum effect in the aboveground part is shown by the GL, in the roots of the RL and the BL. Conclusions. The established effects of selective light irradiation are manifested differently in the aboveground and underground parts of seedlings. Possible mechanisms of connection of a condition of antioxidant system with separate aspects of signaling in photomorphogenesis of plants are discussed.

Pisum Sativum L

A field experiment was conducted at botanical garden of Department of Biology, College of Education for Pure Science (Ibn Al-Haitham), University of Baghdad, during the growth winter season of 2016-2017 to study the effect of different concentrations (0, 10, 20) mg.L-1 of abscisic acid and (0, 50, 100, 150) mg.L-1 of vitamin C and their interaction on some plant hormones of pea plant (Pisum sativum L.). The results showed that ABA 20 mg.L-1 decreased IAA about 27.44%, GA3 about 19.73% and Kinetin 15.37% while vitamin C with 150 mg.L-1 increased IAA 27.43%, GA3 45.31% and Kinetin 58.53%, but ABA increased about 23.01% for ABA and 34.93% for vitamin C compared with control plants. The interaction between them is significant for four plant hormones.

When applied to pea (Pisum sativum L. var. nain hâtif d'Annonay) cotyledonary bud at the time of decapitation, cis-abscisic acid (ABA) induced a decrease in the mitotic indices of the meristem and subapical regions of the bud, in comparison with decapitated but not ABA treated control plants. ABA treatment delayed the entry of the G0–1 nuclei of the inhibited bud into the S phase and then into mitosis. Whatever the ABA concentration (10−3 to 10−7 M), the overall growth of the bud and the elongation of the cortical cells in its subapical region were not affected during the first 48 h. ABA induced an inhibition of bud elongation, all the more important since it was applied later after decapitation. When applied on a 48-h released bud, ABA induced an inhibition of elongation of the bud, a decrease in its mitotic activity, as well as a concentration of the shoot apex nuclei in the G1 phase of the cell cycle. However, this exogenous ABA treatment could not entirely replace the main axis in maintaining the inhibited state of the bud.
