最适盐度

Both species grew poorly in the culture medium absent of salt , especially to a . corniculatum . moderate salt stress ( from 5 to 20 ) can stimulate the growth of both species , and the optimum salinity for growth was from 10 to 15 . when the substrate salinity was higher than 30 , stem height , root length , dry mass increment , net photosynthetic rate fell remarkably for both species
温室内人工盐度梯度栽培下，木榄幼苗地上、地下部分形态和生物量的增长均表现为低盐促进和高盐抑制，以10 15盐度下最适合木榄幼苗的生长；盐度从10增加到50时，木榄幼苗的净光合速率、气孔导度和蒸腾速率均随之下降。
