【摘要】 本文对树木插条生根的形态特征和解剖特性进行了研究。提出了划分插条生根类型的标准,并对44科91属143种树木插条生根进行了分类。通过对白榆、刺槐、毛白杨、I—69/55杨、银杏、木槿等树种插条生根解剖特性的研究,认为愈伤根是从幼嫩愈伤组织中分化发育形成的,愈伤根的发育过程是:愈伤组织→根原基发端细胞→根原基发端→根原基→愈伤根。愈伤组织与生根有直接关系。更多还原

【Abstract】 The morphological and anatomical characteristics of rooting in stem cuttings of woody plants were studied both in greenhouse and field conditions during 1981-1985.The norms of dividing types of rooting in stem cuttings were shown. About 143 species belonging to 44 families 91 genera of woody plants were classified. The study was concerned with the anatomy of Ulmus pumila L., Robinia pseudoacacia L., Populus tomentosa Carr., Populus deltoides cv. I-69/55., Ginkgo biloba Linn.and Hibiscus syriacus Linn.It was clear that roots of calli were formed in the young callus. The process of development of roots of callus in stem cuttings could be divided into five stages : l.the callus, 2.the root initials, 3.the initiation of root primordia,4. the root primordia and 5. the new roots of callus. The callus was directly related to rooting.更多还原
