摘要
用扫描电子显微镜及光学显微镜对我国湖南、广西、江西、四川等省先后报道的宽皮桔类野生种及古老的地方品种的花粉粒进行了观察。根据花粉粒的形态特征,如花粉粒大小、花粉壁的网眼大小、网脊宽窄等,进行了分析研究。结果可分为4种类型。Ⅰ类型以莽山野枯为代表,包括广西皱皮柑;2类型以台湾立花桔为代表;3类型以四川粗皮狗屎柑为代表,包括土枯;4类型以道县野桔为代表,包括江西野桔、广西元桔等。由此可见,宽皮桔类有可能是起源于多源型,而不是起源于单源型。同时看出,莽山野桔具有比道县野桔更原始的野生性状,是宽皮桔类的原始野生种。
The pollen morphological characteristics of some old laudracc and wild mandarins found in Hunan, Jiangxi and Guangxi were studied with SEM and LM.According to the form,size and sculpture of the pollens, the 12 taxis examined were divided into 4 types, typel C. mangshanensis and Guangxi wild orange; type 2 C. tachibana ; type 3 Sichuan wild orange and C. chuana;and type 4 ,C. daoxianensis, Jiangxi wild mandarin, C. poonensis, It was confirmed that loose-shinned oranges might have orginated from multi-prototypes, and that C .mangshanensis is likely to be the mast primary species of loose-skinned oranges.
