查询词典 lanceolate leaf

Glutinosa and Solarium lycopersicum,while Tomato yellow leaf curl China virus and its DNAβinduces distinctive vein thickening and enations as well as leaf curling.To investigate the genetic determinants of the phenotypic differences, we inoculated Nicotiana spp.with infectious clones of TbCSV/DNAβand TYLCCNV/DNAβpseudorecombinants and showed that symptoms co-segregated with the DNAβcomponent.

The test results of acute toxicity were examined with Pearson's degree of fitting. The results indicated that the silkworm was extremely sensitive to Chlorantraniliprole. The median lethal concentration (LC50) was 4.0905×10^(-3) mg/L and median lethal dose (LD50) was 1.1435×10^(-8) mg/larva for the 3rd instar newly exuviated larvae. No toxicity was observed when normal concentrations of Chlorantraniliprole were used to fumigate the silkworm rearing room. Both irrigation and leaf spraying with 1.25×10^(-4) mg/L Chlorantraniliprole solution showed strong systemic transmission properties in root, leaf and whole plant. The residual toxic period of this insecticide to silkworm was very long. Mulberry leaves sprayed with 1.25×10^(-4) mg/L Chlorantraniliprole solution could still cause 100% mortality of the 3 and 5 instar larvae after 60 d. Furthermore, toxic reaction was very quick. The poisoning symptoms emerged within 1~5 h after feeding on the poisonous leaves. The poisoned larvae experienced such symptoms as stopping ingestion, remaining still, vomiting slightly and body atrophy sequentially, and died ultimately.

食下毒力试验结果经Pearson拟合度检验表明，氯虫苯甲酰胺对3龄起蚕的食下致死中浓度(LC50)为4.0905×10^(-3)mg/L，致死中量(LD50)为1.1435×10^(-8)mg/头；药剂在常规浓度下对家蚕无熏蒸毒性；1.25×10^(-4)mg/L稀释药液对桑树根灌和喷叶处理，表现极强的根部、叶部和全株性内吸传导特性；药液对家蚕的残毒期很长，1.25×10^(-4)mg/L稀释药液田间喷雾桑叶，间隔60 d后采叶饲喂3龄和5龄蚕的死亡率均为100%，且中毒反应极快，添食毒叶后1~5 h出现中毒症状，经停止食桑、静伏、少量吐液、蚕体萎缩等过程后陆续死亡。

Our results showed 1 The changes in trends of leaf traits response to the rainfall gradient differed either with species or with a specific trait; 2）The same trends were found at the functional group level, However, leaf traits for grasses tends to be less sensitive, then for forbs, and the legumes is the most sensitive functional group along the rainfall gradient, indicated that the Grass function group is quite strong to the soil moisture content tolerance, and which certainly explained to the local vegetation distribution and the substitution between species.

主要结论如下：1 叶片性状在降雨量梯度上的变化趋势在物种水平上表现出多样化的特点，性状的变化趋势是否有显著的格局取决于物种或特定性状。2 叶片性状对水分梯度的响应在功能群水平上表现出各自的特点，Grass功能群对水分梯度的响应敏感性较低，Forb居中，Legume表现出较强的敏感性，表明Grass功能群对水分的耐受性比较强，这在一定程度上解释了当地克氏针茅草原上目前以禾草类为主的现状，对物种之间的替代有一定的指示性。
