亚热带蜜源植物形态学指标预测泌蜜量初探

A preliminary study on the prediction of nectar secretion by morphological indexes of nectar plants in subtropics

影响蜜源植物泌蜜量因素很多,但人们对蜜源植物本身的形态学指标如何影响不同蜂种泌蜜量的规律所知甚少。本研究利用79种亚热带蜜源植物形态学和泌蜜量数据,探讨了多种因素对不同蜂种泌蜜量的影响。研究结果表明:生长型、耐阴性、花性别和雌雄株等因素均对泌蜜量产生了显著的影响,并且蜜源植物形态学指标与泌蜜量之间建立了回归方程。因此,可以通过植物形态学指标预测蜜源植物泌蜜量,为进一步筛选高产量的蜜源植物指明了方向。

There are many factors affecting the honey secretion of nectar plants,but little is known about how the morphological indexes of nectar plants affect the honey secretion of different bee species.In this study,the morphological indexes and honey production data of 79 species in subtropical nectar plants were collected and the effects of many factors on honey production of different bee species were analyzed.The results showed that growth type,shade tolerance,flower sex and male/female plants have significant effects on honey production.Meanwhile,regression equations were established between the morphological index and honey production of nectar plants.Therefore,it is possible to predict the honey production of nectar plants based on plant morphological indicators,which is helpful to find out the potential high-yield nectar plants.
