三个不同品种费约果的花粉-胚珠比及花粉粒形态的扫描电镜观察
Pollen-ovule ratio and scanning electron microscope observation to pollen morphology of Feijoa sellowiana
摘要
Abstract
P/O of three varieties of Feijoa sellowiana was accounted and breeding systems class was defined;pollens of three varieties of F. selloiviana were observed with scanning electron microscope; and the morphology and taxono-my significance of the pollens were analyzed. The results showed that P/O of 'Coolidge', 'Mammoth' and 'Unique' were 6 ± 2. 37、4. 41 ± 1. 47 and 8. 52±2. 84 and the breeding systems was cleistogamy;Feijoa pollen was radial sym-metry; polar view of the pollens was approximately equilateral triangle, with a clear tricolporate (syncolpate) and go-niotreme; equatorial view of the pollens appears oval; the surface of the pollens had granulated sculpture. At the same time, the morphology of the three varieties was also slightly different, but not obvious. Compared with other four ge-nus of the same family, the pollen morphology of Feijoa was in accordance with the main features of Myrtaceae plant and had important taxonomy significance.关键词
