利用水分亏缺处理鉴定番茄品种抗旱性
Identification on the Drought Resistance of Tomato by Water Deficit
摘要
Abstract
To screen the dry resistant species with high quality,the 10 species of tomato were treated with the water deficit on the 20th d after the 1st cluster,and dry resistance ability was determined by using the average of subordinate function value. The results showed that net photosynthesis rate, root dry weight and total dry weight were decreased ,while soluble sugar contents and sugar/acid radio were increased by the treatment with water deficit. In the meanwhile,the average of subordinate function value was different among the 10 species of tomato. According to the average of subordinate function value,the 8th was the high dry resistant specie,and the 5th and 7th were the dry resistant species.关键词
