摘要:
利用光学显微镜和扫描电镜技术对5个品种红花的花粉微形态特征和营养器官解剖特征进行比较研究。结果表明:5个品种红花花粉外壁突起为刺突和乳突两种,花粉表面均具有皱波和网状雕纹;不同品种红花的叶片角质层厚度、叶脉厚、叶厚、VPD指数、栅栏组织/海绵组织厚度比、根木射线条数差异均达到显著水平;茎中机械组织发达,维管束环状排列、维管束的排列数目上表现种间特异性。这说明5个品种红花孢粉及营养器官解剖结构可能具有一定的耐盐、耐旱的基本生态适应性。
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.
