前言有关对油桐(Aleurites fordjj HemsL)花芽分化的观察研究,据文献记载、仅限于小米桐一个品种类型,而且前人对小米桐花芽分化的观察研究只限于四川,福建二省区,而油桐分布广,载培历史悠久、且受环境条件和异花授粉的影响,其种内变异大,形成的变异类型多。因此,前人的研究,无论以品种类示还是从地理位置上来说,都存在着一定的局限 Preface The observation and study on the flower bud differentiation of Aleurites fordjj HemsL is limited to one type of Millettia only according to the literature, and the observation on the flower bud differentiation of Millettia is only limited to the provinces of Sichuan and Fujian, but the oil Tong widely distributed, carrying culture has a long history, and under the influence of environmental conditions and cross-pollination, within the species variation, the formation of many types of variation. Therefore, the previous studies, both in terms of variety or geographical location, there are some limitations
