As a result, synthesizing the comparison of the characteristics of drought resistance, cold tolerance, barren resistance and production of these ten grasses, we have found that the resistance of Bromus inermis,Festuca arundinacea was better , and consequently Bromus inermis , Festuca arundinacea were proofed to be favorable grasses for developing pasture in northern China in the future. Whereas, Bromus biebersteinii, Festuca rubra,Dactylis glomerata,Phleum pratense,Agropyron desertorum,Agropyron smithii,Elytrigia elongate and Phalaris arundinacea were worse, and therefore measures to local conditions and prudence in the production practice were advocated.

因此，综合抗旱性、耐寒性、耐贫瘠性及田间的生产性能的比较研究，10种牧草中的无芒雀麦、苇状羊茅的抗性表现较好，是今后我国北方地区进行人工草地建设的良好牧草种类；而草地雀麦、紫羊茅、沙生冰草、蓝茎冰草、长穗偃麦草、猫尾草、鸭茅和草芦表现不好，在生产实践中应因地制宜、谨慎推广。

The analysis of correlation indicated that tobacco breeding with higher potassium content has the characteristics of higher stalk height, wider stalk circumference, longer leaf and more leaf number comparatively. The correlations between potassium content and nicotin among top, middle and bottom tobacco leaves were all negative. The correlation among potassium content and malondialdehyde,superoxide dismutase, conductance ratio; and protein, solubility sugar, chlorophyl and free water/bondage water were all attained marked level, however, the essence of correlation was different: the former was negative but the latter was positive. 4.The analysis of heterosis demonstrated there were different degree heterosis in the potassium content of tobacco leaf and other correlated characters, including agriculture, physiology and biochemistry.

相关分析表明，烟叶钾含量性状与株高、茎围和最大叶长的相关性达到了显著和极显著的水平，与叶数的相关虽未达到显著水平，但相关程度相对较高；烟叶钾含量与烟碱在上、中、下三部位叶之间均呈负相关关系，中部叶烟碱与烟叶钾含量的相关达到了极显著水平；烟叶钾含量性状与丙二醛、SOD和电导率以及与蛋白质、可溶性糖、叶绿素和自由水/束缚水之间的相关性均未达显著水平，但相关性质不同，烟叶钾含量性状与前三者之间表现负相关关系，而与后四者之间呈正相关关系；4。

And Changbai larch(Larix olgensis A.Henry)atdoubled CO2 concentration at seedling stage in growth-chamber and WI,HI of several dorminanttree species in MBKPF(1)Under 700μl·1-1 concentration of CO2,the stem height, stem diameter,main root length,root/shoot ratio and the relative proportions of biomass in root,stem and leaf of the seedlings ofKorean pine and Changbai larch had no significant change.

在700μL·L-1CO2条件下与正常浓度下相比较，在一个生长季后，红松、落叶松幼苗的苗高、地径、主根长、根茎比及生物量在根、茎、叶各器官中比例，差异不显著，对落叶松的侧枝数有影响；在第一、二次试验中，落叶松幼苗的平均每株生物量比在正常CO2浓度下大12.2％、14.2％，而红松幼苗的生物量分别减少3.9％、12.8％；红松、落叶松针叶叶绿素含量以及叶绿素a的相对含量在高浓度CO2下受到影响。

Some foods to avoid are listed below: long celery stalks (the "strings" in celery are difficult to digest); cut them into small pieces iceberg lettuce (high in nitrates, no nutritional value) any shelled nuts or seeds (guinea pigs can choke on the shell fragments) raw beans rhubarb There is some confusion as to whether or not potato peelings are good or bad: some books indicate that they are poisonous to guinea pigs, while others say that they are okay in small amounts.

Under the condition [0mmol/L,raise in vermiculite] of phosphorus stress, variation in root morphology and biomass among different soybean genotypes at seedling stage were studied, the result shows: At two-leaf age, higher P-efficiency genotypes(K1 and K2) don't develop their potential advantages; at four-leaf age, some characteristics of K1 and K2, such as lateral root number, lateral root length, root absorbent area and dry weight of shoot are all less reduced than those of intermediate P-efficiency genotypes(Z1 and Z2) and of lower P-efficiency genotypes(M1 and M2), and dry weight of root and R/S of higher P-efficiency genotypes are more increased than those of the others.
