| 摘 要： | 通过细胞胚胎学研究,发现了几种新的烟草花粉胚发育方式,并把发生途径分为三大类+-亚类型:营养细胞(核)发育途径(A—V、A—V_1);生殖核发育途径(A—G、A—G_1);营养核和生殖核发育途径(A—CV、A—CV_1);均等类营养细胞(核)发育途径(B—V、B—V_1)均等类生殖核发育途径(B—G、B—G_1)及核加倍途径(C)。上述发育途径中,以营养细胞(核)途径为主,均等类营养细胞(核)途径次之。讨论了这些发育途径的最终命运。

| Abstract: | After studying cytoembryology, several new ways of tooacco pollen embryo were observed.They are as follows: vegetative cell(nucleus)(A-V, A-V1) , reproductive uncleus (A-G, A-G1), vegetative nucleus and reproductive nucleus (A-GV, A-GV1) , equal vegetative cell (nucleus) (B -V, B-V1), equal reproductive nucleus (B-G, B-G1) and polyplotype of nucleus (C) , of which the vegetative cell development way is the chief one. |
