18个三叶草品种耐热性综合评价
The comprehensive evaluation of heat tolerance of 18 trifolium varieties
摘要
Abstract
The heat tolerance of 18 trefoil varieties were compared and evaluated comprehensively combined with germination and seedling field experiment. The results showed that the germination rate and the germination index declined with the temperature increasing. The seeds from all trefoil varieties could not germinate at the 40℃. The leaf firing rate, the survival rate of seedling and the leaf relative water content were different greatly in all varieties. The results of comprehensive appraisal indicated that the variety'Tetri' was the highest tolerant to heat, the variety 'New Zealand' was higher tolerant, and the varieties 'Haifa','Huia','G18','Gollum','Retor','Badong','Pawera','Emu No 1' and so on were mid-tolerant to heat, 'Crau','Pitau','Aurora','Tetra' were the varieties with lower tolerance to heat, while the tolerance to heat of variety 'Louisiana' was the lowest. It was suggested that the varieties with higher heat tolerance should be planted in Yangtze River and its south region of China.关键词
