摘要:  本文主要综述了6-MBOA 对植食性小哺乳类繁殖的作用及其信息传递的研究进展。植物组织的6-MBOA 是触发植食性小哺乳类繁殖投入时间, 调节个体繁殖性能的特定化学信号。野外和实验室的研究揭示, 植食性小哺乳类的繁殖能对植物衍生的6-MBOA 作出正的反应。在亲代母体和子代间存在6-MBOA 信息传递, 摄入6-MBOA 的母体, 能在妊娠期和哺乳期将其信
息传递给子代, 子代的繁殖对母体传递的6-MBOA 信息亦能作出相应的生理反应, 其繁殖投入的时间和反应强度均依赖于母体所接受的6-MBOA , 且可超越短光照周期对子代繁殖的抑制。
在变动剧烈的不可预测环境中, 兼性机会主义繁殖者, 以获得的6-MBOA 信息调整其繁殖投入。

Abstract: The progress in the studies of 6-MBOA effects on reproduct ion for small mammalian herbivores was reviewed in this paper. 6-MBOA in food plant can trigger reproductive effort and regulate reproductive performance of small mammalian herbivores. Studies in laboratory and field suggested that reproductive development of mammalian herbivores has positive responses to food derived 6-MBOA information, and this information can promote reproductive development of individuals. There exists 6-MBOA informational transfer between mother and offspring, and mature female ingested 6-MBOA could transfer the information to their offsprings during the periods of gestation and lactation. Reproductive development of offspring can make appropriate physiological responses to maternal transferred information of 6-MBOA , and these response degrees depend upon maternal received 6-MBOA. Offspring received 6-MBOA information from mother could override the reproductive suppression caused by short photoperiod. Facing the environments with fluctuation in weather conditions and unpredictability of food resources, the opportunistic reproductive individuals regulated their reproductive effort based on acquired 6-MBOA information from their mothers and food plants.
