Effects of Spraying Potassium Sulfate on the Growth and Development and Resistance Physiology of Potato under Drought Stress

doi:10.7668/hbnxb.2015.S1.085

Abstract

Abstract: The effects of spraying potassium sulfate on the growth and development and resistance physiology of potato under drought stress were reported in this paper.The results showed that drought stress reduced the growth of the potato seedlings,the contents of chlorophyll,carotenoid,root vigor decreased,the activities of antioxidative enzymes and malondialdehyde (MDA) contents osmoregulation substances increased in leaves.The results also showed that the damage of potato seedlings caused by drought stress was alleviated significantly by spraying potassium sulphate solutions,and the effects was the best when the spraying amount of potassium sulphate was 3.5 g per plant.The plant height,root weight,stem diameter,tuber weight,and overground part weight increased,root,stem and leaf water contents also increased,chlorophyll,carotenoid contents were increased,soluble sugar,proline were increased and then decreased,MDA contents decreased wren the planted were treated with K-1 and K-2,the activities of superoxide (SOD),peroxidase (POD),catalase (CAT) enhanced.Our results provide evidence that spray potassium sulphate solution may alleviate the damage caused by drought stress on potato seedlings through improving the activities of antioxidase,decreasing MDA contents,increasing soluble sugar and proline contents,enhancing the accumulation of photosynthate,thus promote seedling growth and tuber yields,improving the nutrition and quality of potato tubers.
