不同品种红花营养器官解剖结构及孢粉特征研究
Study on vegetative organs anatomical structure and pollen feature of different Safflower varieties
摘要
Abstract
The pollen features and vegetative organs anatomical structure of the five safflower varieties were examined using light microscopy(LM)and scanning electron microscopy(SEM). The results indicated that the pollen characteristics of five safflower varieties were basically the same,but the jut of exine was divided into two types for spike and mastoid. There were the regular and reticular sexine ornametation on pollen surface. The differences involving cuticle thickness of leaf,vein thickness,leaf thickness,VPD index,the ratio of palisade tissue and spongy tissue,the number of vascular bundles and number of wood-rays between five varieties were significant. The machinery organization of stems very developed,vascular ring arrangement. These results implied that anatomical structure of safflower have drought and saline stress adaptability.关键词
