Effect of low boron supply in turnip plants under drought stress

Turnip (Brassica rapa L.) plants were grown in Perlite with low (< 2.5 μM) or adequate (25 μM) boron supply under well-watered and drought conditions for 12 weeks. Dry mass of leaves and roots was reduced under drought by about 61 and 56 % in plants supplied adequately with B, while up to 84 and 74 % under B starvation. Drought reduced B content by about 70 and 82 % for B-sufficient and B-deficient plants, respectively. According to the chlorophyll fluorescence parameters, the photosynthesis processes conserved their normal activities under low B supply in well-watered plants, while a serious damage to photosystem 2 occurred under drought stress. Stomatal limitation was the most important cause for a 17 % lower net photosynthetic rate (PN) of drought stressed B-sufficient plants. In B-deficient plants, however, both stomatal and non-stomatal limitations were involved in 53 % reduction of PN. Low B supply reduced strongly leaf water potential.
