为比较春石斛栽培品种Dendrobium Second Love‘Tokimeki’与金钗石斛的粗多糖、精多糖(除蛋白多糖)和多糖水洗组分(过层析柱分离的水洗组分)的免疫活性差异,分别对昆明小鼠灌胃上述6种不同纯度的多糖,观察其对小鼠脏体指数、迟发性变...为比较春石斛栽培品种Dendrobium Second Love‘Tokimeki’与金钗石斛的粗多糖、精多糖(除蛋白多糖)和多糖水洗组分(过层析柱分离的水洗组分)的免疫活性差异,分别对昆明小鼠灌胃上述6种不同纯度的多糖,观察其对小鼠脏体指数、迟发性变态反应、抗体积数和小鼠腹腔巨噬细胞吞噬百分比与吞噬指数等免疫学指标的影响。结果表明:2种石斛的免疫活性随多糖纯度的提高而增强,纯度最高的多糖水洗组分免疫活性最强,且各指标均显著高于对照。D.Second Love‘Tokimeki’和金钗石斛同等纯度的多糖在胸腺指数、脾脏指数、小鼠耳肿胀率及小鼠抗体积数上均无显著差异,而D.Second Love‘Tokimeki’的3种不同纯度多糖的吞噬指数均达到了与金钗石斛多糖水洗组分无显著差异的水平。综合来看,栽培品种D.Second Love‘Tokimeki’的多糖免疫活性与金钗石斛多糖相近,具有良好的药用开发价值。展开更多
The effect of extraneous GA3,6-BA on the flowering rate,the number of flower,the flowering time,and flowering qulity of two nobile-type Dendrobium,D.Corona×(D.Malones×D.Love)(D1)and D.Red Emperor×D....The effect of extraneous GA3,6-BA on the flowering rate,the number of flower,the flowering time,and flowering qulity of two nobile-type Dendrobium,D.Corona×(D.Malones×D.Love)(D1)and D.Red Emperor×D.Love Hunter(D2),were tested.The results indicated that the concentration and kind of used hormone had different effect on the hybrids.D1 should be treated in 25 mg·L-1 GA3 and 800 mg·L-1 6-BA,which promotes the flowering and the quality of flower.But D2 should be treated in 10 mg·L-1 GA3 and 800 mg·L-1 6-BA.展开更多
