4.Through natural selection, weeds have developed efficient mechanisms of root and snoot growth.
7.the only son of my mother, earnestly beg you to accept in token of our gratitude…
8.Three-year continuous observations of the growth and the root development of Prunus armeniaca in arid areas on the application of DBOL have shown as follows: 1) the survival rate of its naked seedlings after planting increased by 10.5%～14.5%;
9.The results showed that under NaCl stress,the dry mass,chlorophyll content and photosynthetic rate of grafted seedlings were 67.8%,8.8% and 31.1% higher than those of own-root seedlings,respectively,and the antioxidant enzyme activities were significantly higher while the O2-· producing rate and the hydrogen peroxide(H2O2)and malondiadehyde(MDA)contents were significantly lower in grafted seedlings leaves than in own-root seedlings.
10.Vermiculite was the optimum medium for Rieger Begonia micropropagation in vitro, the survive rate of the root regeneration plant was 93.8%.
