国家二级保护植物翅果油树传粉生物学的初步研究

对翅果油树进行了传粉生物学的野外观察和实验表明：（1）翅果油树的花具有自花传粉的结构特征，同时具有蜜腺，又具备异花传粉的特征。传粉者主要是一种家养的蜜蜂。（2）翅果油树花形态结构与传粉者的形态和传粉行为非常协调和适应，昆虫的传粉部位主要是头前部和胸部。（3）蜜腺的产蜜量大，开花后1～2天蜜腺分泌量最大。对传粉昆虫竞争中具明显优势。昆虫的访花频率明显高于同花期的其他植物。（4）翅果油树没有融合生殖现象。

The Primary Study on Pollination Biology of a Protective Plant,Elaeagnus Mollis Diels

Field and experimental observations on pollination in Elaeagnus Mollis Diels showed that:(1)Elaeagnus Mollis Diels can go self-and cross-pollination.The effective pollinators were native captive bees in the species.(2)The floral morphological characteristics of Elaeagnus Mollis Diels are harmonied with the pollinator's morphological structure and pollination behavior.The pollinators use their heads and thoraxes to transfer pollens.(3)Elaeagnus Mollis Diels has floral nectary structure and secreting nectar yield reaches the peak 1~2d after its blooming.Because of ample nectar yield it has obvious advantage in attracting the pollinators,and the visiting frequency of floral visitors on Elaeagnus mollis Diels was remarkably higher than other plants at same flowering time.(4)There is no apomixes in Elaeagnus Mollis Diels.
