And Kamethur on Growth And Productivity of Sunflowerstudying the Effect of Plant Growth Regulators Ivin, Methyur

In field conditions, the effect of plant growth regulators Ivin (N-oxide-2,6-dimethylpyridine), Methyur (sodium salt 6-methyl-2-mercapto-4-hydroxypyrimidine), Kamethur (potassium 6-methyl-2-mercapto-4-hydroxypyrimidine) on and productivity sunflower (Helianthus annuus L.) variety Bastion was studied. The growth-regulating activity Ivin, compared with auxin IAA (1H-Indol-3-yl)acetic acid). It found that treatment seeds before planting in soil water solutions Kamethur, used at a concentration 10-7M, contributes to an increase morphological parameters (length shoot root, fresh weight basket) biochemical (content chlorophylls b, carotenoids) grown conditions for 3 months. higher than same 10-7M. obtained results confirmed possibility using length basket, content Bastion.
