内叶片 meaning in Chinese

intra vane

Thirdly , this paper compared the different responses of plants to these two stresses , the change of the defensive enzyme activity and the rate of losing water of leaves was different at two different stresses . the rate of losing water of leaves at drought stress was more rapid than that at salt stress , the leaves would wither and the change of activity of enzymes notably at drought stress , these results showed that the damage to plants was result from the oxidation at drought stress . at salt stress , the content of relative water of leaves changed slightly as well as did the activity of enzymes , these results showed that the damage to plants was caused by poison of ion and lack of nutrition
三、通过研究两种冰草植物对两种胁迫的反应指出干旱胁迫和盐胁迫通过不同的途径对植物进行伤害，主要表现在叶片的失水速率和保护酶活性的变化，干旱胁迫短时间内叶片失水速率很快，叶片萎蔫，引起保护酶活性显著变化，表明干旱胁迫主要是通过氧化胁迫对植株造成伤害，而盐胁迫下叶片相对含水量几乎保持不变，表明盐胁迫对植物的伤害主要通过离子毒害和营养亏缺造成。
