Abstract
The objective of this work is to elucidate the growth and resistance of potato plants under drought stress and its physiological mechanism by spraying boron( Na2B4O7·10H2O solution),in a test of potato planting site of Tiaoshan Farm of Jingtai County in Gansu Province. Moderate drought and mild drought treatments were performed on two ridge land,every boron concentration per three meter sprayed 166. 7 mL Na2B4O7·10H2O,concentration is 0,10,20,30,40 g·L- 1and 60 g·L- 1in turn. The results showed that boron spraying on the leaves of the plantlets increased the tuber yield and biomass of the plantlets under the drought stress significantly. Spraying boron on the leaves of potato plantlets under the drought stress also elevated the activities of superoxide dismutase( SOD),peroxidase( POD) and catalase( CAT),inhibited the producing rate of ultra oxygen anion,and alleviated the decrease in leaf water content and chlorophyll content. De-florating decreased the biomass aboveground and underground. However,by spaying boron on the leaves,the yield of tuber and biomass of the underground part were improved significantly. The results also showed that boron could promote the growth and development of potato plants under drought stress,enhance drought resistance and the yield of tuber,and these effects may be due to the higher translocation of photosynthetic products to the underground part.
