1) xylem fluids
木质部提取液
2) birch extracts
桦木提取液
3) tree extractives
树木提取液
1.
The deterrent effect of tree extractives against Pieris rapae;
树木提取液对菜青虫的忌避作用
4) xylem sap
木质部汁液
1.
By using the method of nutrient solution culture and simulated water stress by PEG 6000,the effects of different nitrogen forms(NO3——N,NH4+-N and NO3——N+NH4+-N)and water stress on root growth,water uptake and xylem sap of rice plants were studied.
15 MPa)下,苗期水稻根系的生长状况、水分吸收状况及木质部汁液特性。
2.
The protein contents in xylem sap of leaves and stems decreased while increased in the roots underdrought stress.
受干旱胁迫的玉米叶和茎木质部汁液中蛋白质含量降低,根中蛋白质含量升高。
5) sap flow
木质部液流
1.
According to different functions of xylem,phloem and bark,the diameter may swell and shrink at different rates,xylem diameter changes were directly linked with transpiration(sap flow in xylem);on the other hand,phleom and bark diameter changes may be not only related with sap flow but also with wate.
木质部直径的变化与木质部液流相关,而韧皮部和树皮直径的变化不仅和木质部液流相关,还与韧皮部储存水以及木质部与韧皮部间的水分交换有关。
6) Extracting solution of protein
蛋白质提取液
补充资料:发酵液透析提取
分子式:
CAS号:
性质:透析提取可在发酵期间把产品连续地直接从发酵液中提取出来,这样可大大改善具有反馈调节特性的代谢物生产。例如,由灰色链霉菌生产放线菌酮(装置如图所示,图暂缺)透析环路管经发酵器后返回萃取器。当溶剂二氯甲烷在透析环路管内流动时,发酵液内的放线菌酮随即被萃入溶剂,接着,溶剂进入萃取器内分层。据报道,该时放线菌酮的收率可较常规法增加将近一倍。
