ABSTRACT

The pot experiment investigated the effect of varied soil moisture (60-70% and 30-35% of capillary water capacity) from flowering through pod setting, on the intensity of photosynthesis, transpiration, intercellular CO₂ and stomatal conductance, some biometrics, seed weight per plant of different pea forms ('Jaspis', traditional cultivar and RRRbRb, homozygotic izoline) and yellow lupin ('Teo', traditional cultivar, and Markiz, self-completing cultivar). The research results showed that in the objects with a lowered moisture of 30-35% capillary water capacity of soil, the intensity of photosynthesis decreases, as well as that of transpiration, intercellular concentration of CO₂ and stomatal conductance in pea and yellow lupin. In the conditions of water deficit, the seed weight per plant in yellow lupin cultivars tested decreased significantly, while the seed weight per plant in the pea forms researched did not vary significantly.

Key words: pea, yellow lupin, water stress, gas exchange indicators.
