Abstract
In order to screen the Lolium multi f lorum L .,varieties with drought resistance ability ,the effects of chlorophyll (Chl) ,superoxide dismutase (SOD) ,malondialdehyde (MDA) and proline (Pro) physiological bi‐ochemical indexes on drought stress of 14 Lolium multif lorum L .were studied .The comprehensive evaluation of drought tolerance was carried out by using the membership function ,which provided scientific basis for the establishment of turf in arid area .The results showed that the chlorophyll (Chl) content and superoxide dis‐mutase (SOD) activity increased first and then decreased ,and the content of malondialdehyde (MDA ) and proline (Pro) increased during the drought stress .The order of drought tolerance was :Raytheon 4>Goalkeep‐er>Qimeng> Quanshun> Caddysand> Pickwick> Accent> Tianma> Jinpaimeidali> Fairway> Debeijipin>Tornado>Doctor>Newspeed2 .关键词
