Some differences between species were found , which can be used lor the identification to subdivision of the genus and supraspecific taxon , furthermore , their structural diversity provided taxonomic evidence and valuable information for phylogeny of the genus 五味子屬植物在種子形態(tài)特征上存在一定的差異,可為屬以下、種以上的分類提供依據(jù)。
( 2 ) the morphological characteristics of leaf epidermis of 16 species were studied . the results show that the morphological characteristics of leaf epidermis have not obvious differences among sections except sect . amana , but there are some differences between species , and indicate that the morphological characteristics of leaf epidermis have some value for the interspecific classification ( 2 )對國產(chǎn)4組16種郁金香植物葉上下表皮的形態(tài)學(xué)觀察,發(fā)現(xiàn)葉表皮形態(tài)在種間均存在一定程度的差異,但在組間,除了有苞組的4個種與其它種類有明顯差異外,其余3組間沒有明顯的差異,表明郁金香屬植物的葉表皮特征在種級水平上具有一定的分類學(xué)意義,可以作為種的劃分及種間親緣關(guān)系探討的參考指標之一。
The results showed that the nearer the relationship of the species , the more similar the zymograms . the zymograms difference between species in different genes is more obvious than ones in the same one . in addition , there is a certain difference between the zymograms of different strains of the same species from different ascocarps and places 結(jié)果表明,親緣關(guān)系愈近的菌株其酶譜的相似性愈大,屬間差異明顯大于種間差異,同菌種的酶譜可因寄主、產(chǎn)地不同等而存一定差異。
We analyzed the alternative in functional phenotypic plasticity responding to variational entironments , consequently , we interpreted the difference between endangerment and wide - distribution of these closely related species , and the results showed : 1 all of the daily changes of photosynthetic rate responding to different water status show " double apices " except m . d , the daily changes of photosynthetic rate in m . d shows " simple apices " responding to arid soil water content , while " double apices " responding to the other soil water content . emerging time of daily maxim of pn is difference between species and between treatments . daily course of transpiration and stomatal conductance of these for species all show " double apices " , but the emerging time of daily maxim of transpiration rate and stomatal conductance rate are all different between species 結(jié)果表明: 1 、除小魚仙草外,四物種的光合速率日變化在不同水分梯度下均表現(xiàn)出“雙峰型” ,小魚仙草的光合速率日變化在于旱時表現(xiàn)出“單峰型” ,其余水分梯度下表現(xiàn)出“雙峰型” ,種間和梯度間日最大光合速率出現(xiàn)時間有一定的差異;四物種蒸騰速率和氣孔傳導(dǎo)力日進程也表現(xiàn)出“雙峰型” ,但種間日最大氣孔傳導(dǎo)力和蒸騰速率出現(xiàn)的時間也存在一定的差異。
