Synthetic Growth

Growth response of <i>Pinus silvestris</i> hypocotyl sections to some synthetic growth regulators and related substances was studied. Elongation of hypocotyl sections was stimulated by naphtaleneacetic acid, indole-3-acetic acid, in-dole-3-propionic acid, indole-3-butyric acid, 2,4-dichlorophenoxyacetic acid, indoleaoetic amide, indoleacetic nitrile and coumarin. Indole-3-acetic acid and naphtaleneacetic acid extended period of growth up to 16 and 24 hours, respectively. Growth was inhibited by kinetin, trans-cinnamic acid and 2,3,5-tri-iodobenzoic acid. No effect of gibberellic acid, tryptophan and biotin was observed.

Complex Preparation

Currently, the expansion of research to find new efficient and environmentally friendly plant growth regulators is an urgent task of agricultural biotechnology. One of the main requirements of the modern development of crop production using technologies for the use of new plant growth regulators is, along with the environmental friendliness of new drugs, both at the application stage for foliar feeding of plants and improving the quality of the final product. One of the new drugs that meet these requirements is a complex preparation of 1-ethoxysilatrane with crezacin. The work shows the high efficiency of the use of the new apple growth regulator in the processing of apple leaves. As a result of the studies, a synergism of the joint action of 1-ethoxysilatrane and crezacin as part of a complex preparation was revealed during foliar treatment of apple leaves of 3-4 phases and the beginning of flowering by spraying the drug in doses of 15 g/ha. The total increase in apple harvest during foliar treatment of tree leaves was 8.1% or 7.0 t/ha compared with the control. An increase in the quality indicators of gardening products was revealed when using the drug 1-ethoxysilatran with krezacin in terms of the content of dry substances, total sugar, vitamin C and pectin in the fruits. The content in the fruits of nitrates during foliar treatment with a new preparation of tree leaves is reduced by 17.9% compared with the control. The content in the fruits of apples of nitrates during foliar treatment with a new preparation of tree leaves decreases by 17.9%, the lead content by 44% compared with the control.

The experiment on brinjal (Solanum melongena L.) having seven growth regulators viz., control, 30 ppm GA3 , 40 ppm GA3, 50 ppm GA , 20 ppm NAA, 40 ppm NAA, and 60 ppm NAA and two varieties viz., BARI Begun-5 and BARI Begun -10 was conducted at the field of Plant Physiology Section of HRC during the rabi season (November 2011 to May 2013) to find out the suitable variety responsive to growth regulators and to determine the suitable dose of growth regulator for brinjal production. The GA3 (Gibberellic acid) and NAA (Naphthalene acetic acid) had no significant effect on plant height and stem diameter at the end of the crop period and days to 100% flowering. NAA 40 ppm produced highest percentage of long and medium styled-flower, leaf photosynthesis and Fv/Fm (efficiency of photosystem II), number of fruits /plant and fruit yield (45.50 t/ha). The variety BARI Begun-5 was earlier to 100% flowering which took 44 days after transplanting which outyielded BARI Begun-10. NAA 40 ppm coupled with BARI Begun-5 gave the maximum Fv/Fm, long-styled flower percent, number of fruits/plant, and the highest fruit yield (49.73 t/ha).
