| 摘 要： | 采用石蜡切片法,对红麻和大麻状罗布麻的营养器官进行解剖学观察.结果显示:(1)红麻和大麻状罗布麻叶片均为异面叶,叶片表皮均被不同厚度的角质层,气孔具孔下室,栅栏组织2层;红麻的栅栏组织比大麻状罗布麻的排列紧密,而海绵组织比大麻状罗布麻的排列疏松;大麻状罗布麻叶片主脉厚度平均值为489.61 μm,而红麻仅为369.29...

| Abstract: | The anatomical structure of nutritive organs of two Apocynum species(A.cannabinum L.and A.venetum L.)were studied by using the method of paraffin section. The results were as follows:(1)The leaf of two Apocynum species was bifacial. The leaf-epidermal cell of two species had cuticle layer with different thickness. Substomatic chamber developed well. Both had two layers of palisade tissues. Compared with A.cannabinum,the palisade tissues of A.venetum arranged more tight,but spongy tissues more loose. Vein ti... |
