| 摘 要： | 在干旱条件下,苹果抗旱系数与叶片相对含水量、离体24小时保水力、比叶重、叶片水势、光合速率呈正相关;与叶片水分饱和亏呈负相关。采用模糊隶属法对红星/山定子、国光/山定子、金冠/山定子、秦冠/山定子、红富士/山定子5个品种的6种抗旱生理生态性状作了综合评价,以平均抗旱隶属值为依据对品种抗旱性强弱进行排序。此法简便有效,准确性高。

The Application of the Method of Fuzzy Subordination to the Comprehensive Appreciation of the Drought Resistence of Apples |

| Abstract: | Under the condition of drought,the coefficient of drought tesistence presents the posi- tive correlation with the leaf's relative water content,the effect on keeping water after leaving the tree 24 hours,SLM,the flow of water in leaf and the rate of photosynthesis,and the negative cor- relation with the water being saturated or unsaturated.A comprehensive appreciation was made of six physiological and ecological characters expressed in their anti-drought ability of five species of apples (Starking/M.baccata Borkin,Ralls/M baccata Borkin,Golden Delicious/M baccata borkin,Qin guan/M.baccata Borkin,and Red Fuji/M.baccata Borkin)and we have put them in order of anti-drought abilities based on the average values of subordination.This way is easy,ef- fective and highly accurate. |
