植物在水分胁迫下脯氨酸积累的研究──Ⅲ．外源脱落酸、细胞分裂素与脯氨酸积累和叶气孔变化的关系

The Study of Proline Accumulation in Plant under Water Stress Ⅲ. The Relationships among ABA,6-BA and Proline accumulation and Leaf Stomata

研究了在水分胁迫下，两种禾草体内ＰＲＯ、叶气孔、外源ＡＢＡ和６－ＢＡ之间的相互依存关系。认为ＰＲＯ积累中气孔因子能更早的提示ＰＲＯ变化的态势。外源ＡＢＡ，６－ＢＡ及水分胁迫仅仅是促使气孔变化的初级因子。

The relationships among proline, leaf stomata, and exocrine ABA and 6-BA in 2oat varieties under water stress were studied. Results showed that exocrine ABA, 6-BA and water stress only were initial factors that change leaf stomata. It was concluded that stomata could give appearance of proline accumulation earlier than the initial factors.
