PROTECTIVE ACTION OF Β-AMINOBUTYRIC ACID ON BARLEY PLANTS (HОRDEUM VULGARE L.) INFECTED BY BIPOLARIS SOROKINIANA SHOEM
Abstract
Action of the exogenous beta-aminobutyric acid (BABA) on plants of spring barley (Hordeum vulgare L.) variety Magutni in the conditions of vegetative pot experiment was investigated. On a phase of 4th-leave a plants was treated by a solution containing water-soluble polymer and BABA, and in 1 and 9 days their was infected by mushroom Bipolaris sorokiniana. On 21 day after the first treatment the plants which have reached of a phase of heading, sprayed once again a solution of polymer with BABA. Degree of deseased plants, morphology, the content of photosynthetic pigments and a grain crop were estimated. Improvement of morphological and photosynthetic characteristics against infection and increase in weight of grain from one plant is established priming action of the exogenous BABA on the barley plants, caused decrease in degree of infection by mushrooms Bipolaris sorokiniana.
