Two cultivars of radish had high Tolerance Index at the developmental stages of seedling, and their lead contents are both highest among the seven species ( cultivars) of plant which mainly accumulated in roots. 萝卜(春萝1号、春红1号)在幼苗生长阶段具有较高的耐性指数,在7种植物中具有最高的含铅量,其主要蓄积部位是根。
In the meanwhile, the percentage of radish root in the fresh root weight declined, the percentage of rootlet in the fresh root weight increased, and the plant fresh weight reduced. 同时,地下部根系形态学也发生变化,萝卜根比重减少,细根比重增加,植株鲜重降低,根冠比(鲜重)增大。
The mutant 8004 Δ R was attenuated in virulence on host plant Chinese radish but retained its ability to cause the hypersensitive response in non host plant pepper ECW-10R. 该突变体8004ΔR对寄主植物的致病力比野生型菌株显著降低,而在非寄主植物辣椒ECW-10R上仍能引起过敏反应。
The technical system of cytoplasm identification of radish germplasm and the system of molecular marker-assisted developing elite maintainer has not been established, the occurrence and the mechanism of plant male sterility still remain mysteries that have not been unveiled thoroughly. 然而萝卜胞质鉴定的技术体系和分子标记辅助选择候选保持系的技术体系尚未建立,雄性不育产生的机理至今尚未完全阐明。
