The experiment identified weed control spectrum of toxin and sensitivity to main crops. The result showed that dayflower and goosefoot were most sensitive to toxin with injury response of level 4, followed by redroot pigweed and eragrostioid with injury response of level 3 and level 2, respectively. Among the main crops, corn and sorghum were susceptible to toxin while wheat, soybean and peanut were insensitive.
粗毒素杀草谱和对作物安全性测试结果为:鸭跖草和藜对毒素最敏感,伤害反应为4级;反枝苋和虎尾草伤害反应分别为3级和1级;玉米和高粱对粗毒素敏感,小麦、大豆和花生对粗毒素不敏感。

Result In peanut seedling stage, spraying 900 ml/hm^2 quizalofop-P-ethyl EC on the grass weeds such as Barnyard grass, Green bristlegrass and Goosegrass had 100% control effect, but it had a poor control effect on some broad-leaved weeds. While, spraying 600 and 720 ml/hm^2 quizalofop-p-ethyllactuofen EC had remarkable effects not only on the grass weeds such as B. grass but also on the broad-leaved weeds such as Purslane, Cirsium setosum and Dayflower, with the control effect of more than 80%. Both of the 2 herbicides would not produce some slight contact drug spots on the part of peanut leaves and the drug spots on the leaves could be recovered in 1 to 2 weeks, which couldn't affect the growth and yield of the peanut in middle and late stage. So the 2 herbicides had good selectivity.
结果]在花生苗期喷施900 ml/hm^2精喹禾灵乳油对稗草、狗尾草、牛筋草等禾本科杂草具有100%的防效,但对一些阔叶杂草防效较差,而喷施600和720 ml/hm^2精喹乳氟禾乳油则除了对稗草等禾本科杂草有特效外,还对马齿苋、刺儿菜、鸭跖草等阔叶杂草具有显著的防效,均达80%以上。2种除草剂均对花生叶片局部产生一些轻度的接触性药斑,药斑在12周内可恢复,不影响花生的中后期生长及产量,具有很强的选择性。

The results showed that temperature and CO2 concentration coupling had great effects on the photosynthesis biomass production of Vitex negundo and Setaria viridis; light intensity and CO2 concentration were the key factors for P and T of Agrimonia pilosa and Commelina communis; the temperature change had little effect on A-Ci curve of Agrimonia pilosa and the photosynthesis of Vitex negundo was not sensitive to temperature change.
结果表明,温度与CO2浓度耦合对荆条和狗尾草光合物质的积累影响较大;光照和CO2浓度是影响龙牙草和鸭跖草净光合速率和蒸腾速率的关键因子;荆条光合作用对温度变化不敏感;温度变化对龙牙草A-Ci曲线影响不显著。

The phylogenetic trees supported that Eriocaulaceae be treated as Eriocaulales because this family always been a nature independent group connected with other families. Eriocaulaceae grouped with Commelinaceae, which supported the close relationship and parallel evolution between the two families. Juncaceae was not close to Eriocaulaceae and more primitive. The relationship between Juncaceae and Cyperaceae was closer than that between Juncaceae and Poaceae. Among these families, Poaceae was the most primitive family and far from Eriocaulaceae. Also in Eriocaulaceae, Eriocaulon was supported to be more primitive.
从构建的系统发育树可以得到:①谷精草科独立形成一个植物类群,支持谷精草科独立成为谷精草目;②谷精草科与鸭跖草科聚成一个大的类群,说明两科的亲缘关系较近,并且表现为平行进化;③灯心草科不近缘于谷精草科,与禾本科相比,灯芯草科与莎草科之间存在更近的亲缘关系;④在进化程度上,灯心草科比谷精草科原始;禾本科与谷精草科的亲缘关系最远,并且在这几个科中处于最原始的进化地位;⑤系统树还支持谷精草科内部的系统关系,支持谷精草属在谷精草科中的原始系统位置。
