CONTENT AND RATIO OF PHOTOSYNTHETIC PIGMENTS IN STIPULES OF WINTER PEA WITH USING DIFFERENT GROWING TECHNOLOGIES

The article describes the results of research on content and ratio photosynthetic pigments in stipules winter peas using different cultivation technologies. objects study were pea plants (Pisum sativum L.) variety NS Moroz, plant growth regulator (PGR) Endofit L1 RK, bacterial preparation Bioinoculant BTU-r, microfertilizers «LF-Bobovi» Biobor 140. purpose our was to formation under action Endophyte their complex applying foliar treatment systems with «LF- Bobovi» Analysis chlorophyll carotenoid alcohol extract (96.0%) performed a spectrophotometer Ulab − 102UV (China) at values wavelength: λ = 441; 649; 665. volume working solution 25 ml. Calculations these indexes according formulas H. K. Lichtenthaler. During period, influence regulator, preparation, fertilization b, sum, concentration carotenoids evaluated. indicate dependence indicators use drug, as well fertilization. It found that implementation phase 3-5 (in phases buttons) tank mixtures micro fertilizers (1.5 l / ha 2.5 ha) 140 (1.0 led an increase total amount content. highest chlorophylls variant combined pre-sowing seed RK (0.01 t), BTU-r (2 t) ha).The search for ways opportunities grain yield varieties Moroz due introduction new technological methods its remains relevant. A possible problem improving productivity is mechanisms regulators, inoculation symbiotic microorganisms, feeding chelated microfertilizers.
