泡桐为我国著名速生优质丰产的重要树种。本文仅就几种雄性不育的泡桐作一初步的细胞形态学方面的探讨,以供科研、生产单位参考。一、材料与方法不育材料为楸叶泡桐(Paulownia catalpifolia)、山明泡桐(为兰考泡桐 P.elongata 的一种类型)及宜昌兰考泡桐(暂称,在宜昌发现的兰考泡桐另一种类型)。能育材料为白花泡桐(P.fortunei)、毛泡桐(P.tomentosa)、兰考泡桐(P.elongata)。1976—1978年初,在 Paulownia is a famous high-yielding fast-growing important tree species. In this paper, only a few male sterile Paulownia for a preliminary study of cell morphology for scientific research, production units for reference. I. MATERIALS AND METHODS Sterile materials were Paulownia catalpifolia, Paulownia paulownia (a type of P.elongata) and Ipomoea cairica (tentatively, another type of Lantana camaldulensis found in Yichang) ). Fertile materials are P. fortunei, P. tomentosa, P.elongata. 1976-1978, at
