INVESTIGATION OF SOW LENTIL REACTION TO IONIZED ALKALINE WATER DURING EARLY STAGES OF ONTOGENESIS

Abstract

Plant physiological processes related to plant growth and development strongly depends on the environmental stress factors. Response to stress appears as a complex of different reactions with a particular feedback on plants. Influence of ionized alkaline water to sow lentil physiological reactions was investigated by analyzing changes in biomass accumulation, assimilates partitioning and pigment content. Ionized alkaline water at (8.4 pH) was applied during 6–7 and 8–9 leaves development stage. According to experiment results, at the latest stage of investigation, ionized alkaline water increased lens dry matter content more than 1.44 times. During experimental time increase in dry matter content was 13.96 %, when control plants gained only 3.47 %. Ionized alkaline water application resulted in 8.58 % significantly higher root dry matter content compare to control variant. Results of our experiment revealed the significant effect of ionized alkaline water to chlorophyll content. Chlorophyll a and chlorophyll b in control plants had a tendency to decline, whereas in experimental variant with ionized water, increase in pigment concentration was observed.
