The main invasion method of grub is invading directly form leaf gap of the leaf sheath and bore a hole in leaf sheath. 幼虫侵入水稻方式以从剑叶叶鞘缝侵入和从剑叶叶鞘处咬孔侵入为主。
Studies on Stomatal Characters and Leaf Temperature Gap of Different Maize Genotypes 玉米不同基因型气孔特征和叶温差的研究
Bud under the third leaf mesophyll differentiation has become more complete, palisade tissue and spongy tissue Obviously, the palisade tissue cells close, 2~ 3 layers of spongy tissue cells loose the larger gap. 芽下第三叶的叶肉分化已经趋于完全,栅栏组织和海绵组织明显,栅栏组织的细胞排列紧密,有2~3层,海绵组织的细胞排列松散,细胞间隙较大。
The adventitious roots of the burl formed closed to leaf gap and also beared on leaf trace. 节部不定根靠近叶隙,也与叶迹有关,根原基形成早。
Tea leaves of different maturity palisade mesophyll cells were the long column. The spongy tissue of young Leaves arrangement regularity, cell gap was small, mature leaf mesophyll cells in spongy tissue arranged in a more relaxed, and large cell gap. 不同成熟度茶树叶片的栅栏组织叶肉细胞均为长柱状,嫩叶的海绵组织叶肉细胞排列较紧密,细胞间隙小成熟叶的海绵组织叶肉细胞排列较松弛,且细胞间隙较大。
