摘　　要： 余甘根系分布深而广.两年生树主根可长达树高的2倍以上;水平根长为枝展的3倍以上,吸收根群发达,且具内生菌根.余甘叶片小,为0.58±0.03cm^2;叶脉密度大,为19±1.04条脉/cm^2叶面积;栅栏组织厚度/海绵组织厚度高达1.06.这些旱性形态解剖特征构成了余甘耐旱性的基础. Phyllanthus emblica L.has a huge root system.The lenghth of its radicle was twice of the height of the shoot; and the lenghth of level root was three times of the branch.There is VA mycorrhiza in the young root.Its leaf was quite small, being 0.58±0.03cm; the lasf veins was very density, being about 19 per cm leaf area; the palisade tissue was rather thick, the thickness of it/that of aponge tissue was 1.06.These morphological and anatomic characters may be the basis of P.emblica L.resisting to drought.
