Abstract
Description
Изобретение относится к физиологии растений, а именно к способам оценки устойчивости растений к засолению почвы, и может быть применено в растениеводстве и селекции при отборе солеустойчивых сортов. The invention relates to plant physiology, and in particular to methods for assessing the resistance of plants to soil salinization, and can be used in crop production and selection during the selection of salt tolerant varieties.
К аналогам предлагаемого способа можно отнести способы, когда при выращивании растений на засоленных субстратах по всхожести, росту проростков судят о солеустойчивости растений. При этом нельзя оценить как изменяется это свойство в онтогенезе, тогда как известно, что в онтогенезе устойчивость к любым стрессам изменяется, что существенно снижает достоверность оценки. Analogues of the proposed method include methods when, when growing plants on saline substrates by germination, the growth of seedlings is judged on the salt tolerance of the plants. It is impossible to assess how this property changes in ontogenesis, while it is known that in ontogenesis, resistance to any stress changes, which significantly reduces the reliability of the assessment.
Известен способ, по которому о солеустойчивости судят по увеличению электрической емкости корней риса, предварительно обработанных солями. Этот способ применим только к культуре риса, способ трудоемок, так как определяется электрическая емкость извлеченных из почвы корней, предварительно отработанных солями растений, нарушается целостность растений (прототип). A known method according to which salt tolerance is judged by increasing the electric capacity of the roots of rice, pre-treated with salts. This method is applicable only to rice culture, the method is time-consuming, since the electric capacity of the roots extracted from the soil previously worked out by the salts of the plants is determined, the integrity of the plants is violated (prototype).
Целью данного изобретения является повышение достоверности оценки, снижение трудоемкости и ускорение определения солеустойчивости растений. The aim of this invention is to increase the reliability of the assessment, reducing the complexity and accelerating the determination of salt tolerance of plants.
Цель изобретения достигается путем измерения электрического сопротивления листьев без нарушения целостности растений, произрастающих на засоленном субстрате (на полевых участках, где почва засолена или в вегетационных опытах, где создается засоленность субстрата соответствующими солями - хлоридами, сульфатами и др.). Определяют степень изменения электрического сопротивления ткани листьев (ЭСТЛ) в результате солевого воздействия. Чем выше степень воздействия засоления на растение, тем больше изменяется ЭСТЛ в сторону его увеличения. И наоборот, чем устойчивее растение к действию засоления, тем меньше изменяется ЭСТЛ при воздействии засоления. The purpose of the invention is achieved by measuring the electrical resistance of leaves without violating the integrity of plants growing on a saline substrate (in field areas where the soil is saline or in growing experiments where salinity of the substrate is created by the corresponding salts - chlorides, sulfates, etc.). The degree of change in the electrical resistance of leaf tissue (ESTL) as a result of salt exposure is determined. The higher the degree of influence of salinization on a plant, the more the ECTL changes in the direction of its increase. Conversely, the more resistant the plant is to the action of salinization, the less the ECTL changes under the influence of salinization.
П р и м е р. Измеряли ЭСТЛ растений, предпосевно закаленных по методу Генкеля и растений, предпосевно незакаленных после воздействия на них почвенного засоления 0,3% NaCl, что соответствует средней засоленности почвы (таблица). Растения предпосевно закаленные, меньше изменяли ЭСТЛ при воздействии почвенного засоления, чем растений, не закаленные к засолению, т.е. проявили себя как более солеустойчивые. PRI me R. The ESTL of plants presowed hardened by the method of Genkel and plants presowed non-hardened after exposure to soil salinity of 0.3% NaCl was measured, which corresponds to the average salinity of the soil (table). Plants are pre-sowed hardened; they have less changed ECTL under the influence of soil salinization than plants not hardened to salinization, i.e. proved to be more salt tolerant.
