Abstract:

Thi rty- two di fferent drough t- resistant g ermplasm w ere used to study thestomatal cha racters a nd rela tion betw een stomata l characteri stics and droug ht resi stancein field drought conditio n. The result s show ed that there w ere sig ni ficant ly genety pedi fference amo ng g ermplasm in stomatal density ( SD) , stoma tal leng th ( SL) and totalstomatal leng th per uni t leaf area ( SD× SL ) . The stomatal characteristics w erecor related wi th the drought resistance, but no t sig nificant ly. Dro ugh t- resista nce ofcrop are cont ro lled by gene, ex press of g ene and phycho logical a nd biochemicalcha racters. Thus i t i s a combinatio n of processes.
