4种魔芋资源的裂片及其表皮细胞的形态学比较研究

以白魔芋等4种魔芋资源为材料,对其裂片及表皮细胞进行形态学比较研究,结果表明:白魔芋裂片披针形,尖端长尾状,钝齿状叶缘,表皮细胞含丰富内含物;花魔芋裂片卵圆形,尖端渐尖,基部左侧偏大,叶缘浅波状,气孔器呈平行型排列;珠芽魔芋裂片椭圆形,皱波状叶缘,基部盾圆,表皮细胞为4种资源最大;甜魔芋裂片卵状三角形,尖端盾尖,气孔器呈不等型排布.

Morphological comparison and study made of the leaves and epidermal cells of four Amorphophallus species show that the leaf of A.albus is lanceolate in shape,its tips are tail-like,its margins are blunt dentate,and its epidermal cells contain abundant inclusion;the leaf A.konjac is ovate in shape,its tips are acuminate,its margins are light wave-like,the left side of its base is wider than the right side,and the stomata in their epidermal cells are arranged in parallel;the leaf of A.bulbifer is oval in shape,its margins are wave-like,its base is blunt round,and its epidermal cells are the largest of the 4 species;and the leaf of A.dunnii is ovate-triangular in shape,its tips are blunt sharp and the stomata are irregularly arranged in its epidermal cells.
