摘要: 用气相色谱法测定苹果抗旱种新疆野苹果[Malus sieversii (Ledb) Roem. ]和较不抗旱种平邑甜茶[M. hupehensis (Pamp) Rehd.]根系、叶片和木质部汁液茉莉酸(jasmonic acid , JA) 对快速和缓慢水分胁迫的反应。结果表明, 两个种对水分胁迫反应灵敏。水分胁迫下两个种叶片气孔阻力与根系、木质部汁液中JA 含量呈显著对数相关关系, 而与叶片中JA 含量相关不显著。

Abstract: Two apple species with different drought resistance were exposed to a polyethylene glycol-induced water deficit . The concentration of jasmonic acid (JA) in roots , leaves and xylem sap were measured by gas chromatograph. Sensitive increases of JA in roots , leaves or xylem sap were showed in two species. A significant logarithm correlation existed between leaf stomatal resistance and concentration of JA in xylem sap or roots. This suggest that JA in xylem sap may be the signal responsible for communication between roots and shoots in apple trees under water stress.

Key words: Malus, Water stress, Malus sieversii, Malus hupehensis, Jasmonic acid
