摘要
以双孢蘑菇为试验材料,探究在20℃贮藏条件下双孢蘑菇子实体不同组织部位中脱落酸(ABA)、赤霉素(GA)、生长素(IAA)和玉米素核苷(ZR)含量的变化。结果表明,GA与IAA含量在双孢蘑菇采后贮藏中的变化规律相似,可能协同调控子实体的采后膨大、破膜开伞以及后期孢子的产生过程。ABA和GA在菌柄组织采后的衰老过程中作用突出。ABA可能启动并参与双孢蘑菇采后衰老的过程。与ABA、GA、IAA相比较,ZR分布的组织差异性更显著,可能与采后菌褶的增厚和孢子的形成密切相联。以上结果表明,这4种激素在双孢蘑菇采后贮藏中呈现组织差异性规律,并与双孢蘑菇继续发育和衰老过程有关。本研究结果为寻找有效控制双孢蘑菇采后品质下降提供一定的理论基础。
Changes on the content of abscisic acid(ABA),gibberellins(GA),indole-3-acetic acid(IAA)and zeatin nucleoside(ZR)in different tissues of Agaricus bisporus(Lange Sing)mushroom during 20℃storage were investigated in this study.Results showed that the change pattern of GA and IAA content is similar during postharvest A.bisporus mushroom storage.GA and IAA may synergistically control the processes of cap expansion,protecting veil break and the spore production.Both of ABA and GA play prominent roles in the postharvest senescence process of stipe tissue.ABA may promote and participate in the whole senescence process of harvested A.bisporus fruit bodies.Compared with ABA,GA and IAA,ZR is distributed obviously in different tissues and may closely relate to the gill thickening and spore production.The above mentioned results indicated that the production of the four hormones were difference in different tissues of the A.bisporus mushroom during postharvest storage,which is probably associated with the postharvest continued development and senescence processes.The discovery in this study will provide a theory base for seeking new methods to effectively maintain postharvest quality of A.bisporus mushroom.
