7-15
1.Leaves alternate, leathery, elliptic or obovate-oblong, 7-15 cm long and 5-8 cm wide, entire, densely grayish tomentellate.
2.Speech vocal assessment 4.0 software before and after operation. Results The Jitter, Shimmer, NNE, HNR, SNR normalized after 7-15d post-opertively.
4.According to the length of stop discharging the gangue, the waste hills are divided into four site types: it is class Ⅰ within stopping discharging gangue for 7 years, class Ⅱ in 7-15, class Ⅲ in 15-25, class Ⅳ in more than 25 years.
5.The accumulated temperatures for different growth periods are as following(≥10℃): new tips 35～50d,620-750℃,florescence 7-15d,130-320℃,berry 50-65d,1100-1400℃ and mature 35-50d,640-940℃.
6.More important weeds are Oldworld arrowhead (Sagiltaria sagittifolia) and needle spikesedge (Eleoch-aris yokoscensis). The peaka of grasses, broad-leaf weeds and sedge occurence are during 7-15 days, 15-20 days, 20-30 days respectively after transplanting of rice.
7.Semi-quantitative RT-PCR analysis showed that VEGF receptor Flk-1 mRNA was also time-dependently upregulated in the deafferented hippocampus with its maximal elevation at 7-15 dpl while the Flt-1 mRNA levels remained unchanged at any time point we examined.
9.It turned out that the residues in samples Ⅰ-Ⅳ had been degraded below 0.5 ppm with very few except-ations 7-15 days later after the spray. This amount is much lower than that one lawfully permitted by European Economic Community.
10.RESULTS SMZ and TMP were separated completely in 7-15 min and a good linearity was obtained separately in the concentration range over 50.7-253.7 μg· mL-1,10.1-50.5 μg·mL-1.The recovery rate of each component was not less than 96.5% with the relative standard deviation(RSD) less than 2.72%.
