  1. This experiment to adopt the method that paraffin was cut into slices studied the structural growth process on appearance and dissect of pugionium cornutum ( l ) gaertn in germination period and young sprout ; and to adapt wild flower, fruit, seed and cultivated root, stem and leaf of pugionium cornutum ( l. ) gaertn in leaf lushing period and leaf exhausting period from eerduosi city proceeded the research on appearance and anatomies. the result enunciates : the organs of pugiorium cornutum ( l. ) gaertn in root, stem and leaf have started dividing in germination period ; the transporting tissue and storing water tissue in young sprout period has been divided ; the ransporting tissue is flourishing, but the supporting tissue is unflourishing, so the root, stem and leaf of pugionium cormutum ( l ) gaertn is suitable for edibility

    本試驗採用石蠟切片研究了沙芥發芽期、幼苗生長期各器官形態及解剖結構的變化過程；並對采自鄂爾多斯市野生沙芥花、果實、種子及人工栽培的葉片旺盛生長期、葉片生長衰退期的根、莖、葉等材料進行了形態及解剖學研究，結果表明：沙芥發芽期根、莖、葉各器官內組織已開始分化；幼苗期已分化出發達的輸導組織及貯水組織；葉片旺盛生長期各器官具有發達的輸導組織，但機械組織不發達，因此沙芥的根莖葉適于食用。

    鞭角華扁葉蜂保幼激素滴度的動態
  3. Niche breadth of four dominate populations at three age groups was studied by the methods of resource utilization ability and ratio. the result shows that : symplocos sectchuanensis is a typical gengeration species whi ch resource utilization ability is strong, and distribution is wide. meanwhile, go rdonia acuminata, castanopsis fargesis and pinus massoniana specialized at some d egree in resource utilizationm, their distribution is limited. especially, the ju venile of pinus massoniana specialized outstandingly. with the devlopment of pinu s massoniana, which is the pioneer population in mt. jinyun, the environment become s unfit to it ' s juvenile. it turns to needle and evergreen broad - leaves mixed fo r est. because the tolerance toward shading of gordonia acuminata is lower than tha t of castanopsis fargesis, gordonia acuminata will be substituted by castanopsis fargesis and other evergreen broad - leaves species are the edificators. the popul ation ' s ability of resource utilization is the inner factor of population distri bution and community succession. the distribution of light and the concentrate of nutrient ( such as n ) is the outer factors of community succession

    對縉雲山森林植被的4個優勢種群3個年齡級生態位寬度進行了研究.結果表明，川灰木利用資源的能力最強、分佈廣，為典型的泛化種.大頭茶、栲樹、馬尾松對資源的利用在一定程度上特化，分佈上有一定的局限性.馬尾松的中齡組與幼齡組特化現象十分顯著.縉雲山森林植被的先鋒種馬尾松的發展，導致環境的改變不適于其幼齡個體的生長，群落演替到針闊葉混交林階段，最後發展為以栲樹等為建群種的常綠闊葉林.種群的資源利用能力，是種群分佈與群落演替的內在原因，光因子和營養元素（如n ）是群落演替的主要外部動力
  4. Four species of ceratiodes were studied about organic morphology and embryonal development and biological characteristics. the results were showed as follows : c. arborescens and c. ewersmanniana were more dominant than c. latens and c. lanata in spire and vegetative period. in flowering phase of male flower, c. arborescens and c. latens arrive the maximum peak of flowering during 8 : 00 - 11 : 00. c. lanata arrive the maximum peak of flowering during 11 : 00 - 1 : 00, but in flowering phase of female flower, three species arrive the maximum peak of flowering in 14 : 00 ; temperature of female flower was righter than one of male flower

    本文對駝絨藜屬4種植物進行了器官形態學及解剖學、胚胎發育及生物學特性的研究，結果表明： ４種材料幼苗期和營養生長期的生長狀況均是華北駝絨藜、心葉駝絨藜比駝絨藜、北美駝絨藜占優勢；開花規律，華北駝絨藜和駝絨藜雄花均在8 : 00 - 10 : 00達開放高峰，北美駝絨藜在11 : 00 - 1 : 00達開放高峰，而三者雌花均在14 : 00左右達開放高峰。
  5. So far new variety is deficient and difficult to popularize because it is hard to know the eclolgical adaptability of plants, so we ca n ' t adjust measures to local conditions. in this paper, we systematically studied photosynthetic characteristics, light response characteristics, photosynthetic diurnal variation, growth, biomass, seasonal variation of physiological characteristics and leaf anatomy of cydobalanopsis multinervis and michelia foveolta under different shadings ( full light, one layer shading, two layers shading ) by ecophysiologi cal methods
