low growing plant
解釋
矮生植物-
For nutritional substance exists in organic state with weak process of mineralization, the available elements are low, especially a lack of available nitrogen and phosphorus, the soil condition can not meet the needs of plant growing
。有機質含量高，其總氮總磷和鉀的儲量較豐富。由於礦化作用弱，營養物質缺乏，特別是有效氮和有效磷的缺乏難以滿足植物的生長。 -
Both types of vegetation are characterized by dense plant community structure, short growing period and a low productivity
高山種類為主。植物低矮，群落結構簡單，僅為一至二層。 -
Nh4c depletion in the pore water concentration and low n / p ratios ( 3. 7 by weight ) within the macrophyte biomass at the end of the growing period suggest that available n limits plant growth
孔隙水濃度中nh4c的消耗和大型動植物生長末期的低氮/磷比率（重量上佔百分之3 . 7 ）表明，有效的氮元素限制了植物的生長。 -
Abstract : the low expression level of foreign genes in transgenic plants is a puzzling question for researchers in plant genetic engineering. the biosafety concern is now causing a growing public wariness of transgenic plants around the world. this article reviews the new strategies currently used in construction of plant expression vector for plant genetic engineering. these strategies are important for obtaining better expression of foreign genes and developing safer transgenic plants
摘要外源基因在轉基因植物中表達效率低一直是令相關研究者困擾的一個問題.轉基因植物的生物安全性最近在全球范圍內開始引起世人的擔憂.本文簡要介紹了近年來在植物表達載體構建方面所採用的一些新策略，這些策略有助於增強外源基因的表達水平、提高生物工程體的安全性。 -
Secondly, we compared and analyzed the growing state, plant height, flower shape and seed setting ability, etc, of m2 tube seedlings and m3 greenhouse plants treated with low - energy n *. we found that the growth rates of m2 tube seedlings and m3 greenhouse plants were lower than that of control and the growth rate decreased with the treated doses from 60x1015, 40x1015 to 80 x 1015. vfe also found that many phenotypic variations appeared in m2 tube seedlings, including yellowing, lethality, semi lethality, morphological variation ( such as leaf and flower shape variations, plant height variation, etc )
最後，對80次劑量處現的擬南芥的mz代試管稍和60次劑員處理的m3代溫室茵採用rapd技術對dna的差異進行了分析，檢測發現經低能n 」注入處理的材料，其pcr條帶缺失或增加，而對照組未發現明顯的變化，而且條帶的變異率隨劑量的升高而上升，從引物的角度看， 80次劑量處理的比代試管苗的多態性表現為67
