growth vigor
2.To utilize rapeseed male-sterile lines,increase the affinity of cruciferae hybridization and breed new vegetable species,the studies conducted the affinity experiments of hybridization, investigated the cytoplasm effection of hybridization,growth vigor,yield and main nourisgment elementsts of tender flower stelk.
5.To study the suitable method for cattle oviduct simple epithelium cells culture, the epithelium cells were isolated by cutting and 0.25% trypsinization, the exponential phase of growth cells vigor and growth velocity was determined by MTT method, the viable count was detected by the rejection experiment of trypanblau.
6.The calcium products, a variety of elements nitrogen, which is necessary for some nutrients seedling growth can induce root growth seedling vigor, Flower, Bao Lei, 4.2 peach, rapid calcium, nitrogen and other trace elements that can prevent root blight, fusarium wilt, leaf, Blight of Rot. weak seedling bud abortion, a potent rotten peach can enhance seedling drought and frost-proof, anti premature senility, anti-STD calciprivia plant capacity promotion developed root seedlings seedlings healthy and steady early, squaring focus Block Chu high boll early, rapid expansion of peach, peach increased weight gain. ,1999 Chang, the color white lint high, up to 25 to 35% yield.
8.For the inhibition of the ele ment on seed germination and root elongation of wheat, our results showed that l ow concentration of Se (under 0.5 mg·L-1) could promote the seed germination of wheat and its seedling growth, while high concentration of Se ( above 5 mg· L-1) reduces the germination rate of seed, the growth of seedling, its vigor and á-amylase activity markedly.
10.The regularity of dynamic change of several physiological and biochemical indexes during growth and these indexes reflecting on seediling vigor of hazel were investigated in the present study. The results showed as follows. In generally, the vary of chlorophyll a, chlorophyll b and total chlorophyll tend to low-high-low.
