As a result,the venations of Mylabris Fabricius were tentatively classified into three types as follows:Southern type,represented by Oriental species,wing dark brown with a lot of folds,veins stout and highly sclerotic;Plateau type,represented by Qingzang Plateau endemic species,wing ivory-white and semitransparent,only the large cell enclosed by costal margin and MP_ 1+2 obvious;and Northern type,as the transition between the former two types,represented by Palearctic species,wing brown,veins clear and moderately sclerotic.

研究结果将斑芫菁属翅脉归纳为3种类型：1南方型：东洋种，翅深褐色，各脉粗大，骨化程度高，皱褶多而明显；2高原型：青藏高原特有种，翅乳白色，半透明，仅前缘和MP1+2形成明显的大翅室，余脉淡而不显，骨化程度低；3北方型：为以上两种类型的中间过渡，古北种，翅褐色，各脉清晰，中度骨化。

There are 18 species of Paphiopedilum in China. Most of them grow in limestone regions and are epiphytic or terrestrial. There are two types of leaves mottled leaves and green leaves. They distribute in subtropics of China. Five species of subgenus Brachypelalum are the most primitive grou p of Paphiopedilum in China and four of them distributed in the limeston e re gions of Eastsouth Yunnan. Most species of Paphiopedilum distribute in this area,too.

国产兜兰野生种共有18种，主要分布于热带过渡地区，主产西南各省区；大多数种类生长于石灰岩山地，多为半附生兰，呈丛生生长，另一部分生长于酸性砂岩面的腐叶土上，多为地生兰，呈单株生长或分蘖状散生；大部分兜兰分布于较高海拔地区；国产兜兰属中最原始的短瓣亚属绝大部分种类仅分布在滇东南地区与贵州、广西连成一片的岩溶地貌的石灰岩地区，而兜兰属中较进化的兜兰亚属大部分种类在本区皆有分布。

Results indicate that the stigmatic surface morphology of Pedicularis species is related to the type of corolla structure occurring in the species. Pollination studies in 8 Pedicularis species demonstrated adaptation between stigmatic surface morphology and other aspects of floral biology.

拥有更膨大，更粗糙的柱头表面特征的植物种类通常都是具喙或长管种类，而短管无齿种类的柱头平滑且无膨大，相反，对于长管具喙种类而言，柱头在膨大的同时，更形成了发达的&沟回&结构，这种柱头结构式样的不同直观、显著的改变了不同种类的传粉效率。

Both upper and lower epidermis cells are polygonal or irregular in shape in all species studied. The patterns of anticlinal walls are straight, arched or sinuous, and the raphal cuticular striastriae are occasionally observed on periclinal walls. Stomatal apparatus and secretory cells are found on the upper epidermis of several species and on the lower epidermis of all Species. The slomata apparatus mainly belong to the paracytic type and latercylic type; rarely anomocytic type occurs along with the paracytic one.

结果表明：这些植物叶片的上、下表皮细胞呈多边形或不规则形，垂周壁式样为平直、弓形或波浪状，平周壁偶有脊状条纹；少数种类上表皮还有气孔器或分泌细胞，所有种类下表皮具气孔器和分泌细胞；气孔器类型以平列型和侧列型居多，偶尔有无规则型；气孔极区呈稍角质加厚或棒状加厚，稀T形加厚。

It indicate that 200μmol/m2s and 80μmol/m2s low light cause reactive oxygen species quick producing and SOD and CAT acticity enhance, but the latter's increasing cann't offset reactive oxygen species'quick producing, which lead to membrance peroxidize injury on peach tree. 30μmol/m2s low light's injury on peach tree mainly because reactive oxygen species'accumulation.

表明200μmol/m2s和80μmol/m2s的弱光下桃树抗氧化酶活性的诱导提高不足以抵消弱光下自由基的快速生成，从而导致对桃树细胞膜脂的伤害；30μmol/m2s的弱光下桃树活性氧的快速生成加剧膜脂过氧化程度，是造成弱光对桃树伤害的重要原因之一。
