以高丛康维尔蓝莓组培苗为材料,用不同质量浓度的秋水仙素通过浸渍法和培养法进行染色体加倍研究,从形态学、生理生化学、解剖学及细胞学进行比较,以确定能够诱导出多倍体的最佳处理方法和处理质量浓度.结果发现,在形态指标上,0.5,2.0,4.0 mg/mL 秋水仙素浸渍处理1 d 及0.4 mg/mL 秋水仙素培养10 d 后,蓝莓的叶长、叶宽、茎直径、叶厚、茎直径的平均值均显著大于 CK;在解剖结构上,0.5 mg/mL 浸渍1 d 和0.4 mg/mL 培养10 d 后,其气孔变大,密度变低,为椭圆形,保卫细胞的淀粉粒减少,0.5,2.0 mg/mL秋水仙素浸渍1 d 和0.4 mg/mL 培养10 d 后均使细胞核明显变大;在生理指标上,0.5 mg/mL 浸渍处理1 d后显著提高了蓝莓 SOD 酶活性,2.0,4.0 mg/mL 秋水仙素浸渍处理1 d 能够显著提高可溶性蛋白质含量,其中后者还显著提高了其叶绿素 A 含量.可见,0.5 mg/mL 浸渍1 d 和0.4 mg/mL 培养10 d 后,蓝莓植株发生多倍性变异的可能性最大,但还需后续的大田鉴定,才能最终确定多倍体植株.
以高叢康維爾藍莓組培苗為材料,用不同質量濃度的鞦水仙素通過浸漬法和培養法進行染色體加倍研究,從形態學、生理生化學、解剖學及細胞學進行比較,以確定能夠誘導齣多倍體的最佳處理方法和處理質量濃度.結果髮現,在形態指標上,0.5,2.0,4.0 mg/mL 鞦水仙素浸漬處理1 d 及0.4 mg/mL 鞦水仙素培養10 d 後,藍莓的葉長、葉寬、莖直徑、葉厚、莖直徑的平均值均顯著大于 CK;在解剖結構上,0.5 mg/mL 浸漬1 d 和0.4 mg/mL 培養10 d 後,其氣孔變大,密度變低,為橢圓形,保衛細胞的澱粉粒減少,0.5,2.0 mg/mL鞦水仙素浸漬1 d 和0.4 mg/mL 培養10 d 後均使細胞覈明顯變大;在生理指標上,0.5 mg/mL 浸漬處理1 d後顯著提高瞭藍莓 SOD 酶活性,2.0,4.0 mg/mL 鞦水仙素浸漬處理1 d 能夠顯著提高可溶性蛋白質含量,其中後者還顯著提高瞭其葉綠素 A 含量.可見,0.5 mg/mL 浸漬1 d 和0.4 mg/mL 培養10 d 後,藍莓植株髮生多倍性變異的可能性最大,但還需後續的大田鑒定,纔能最終確定多倍體植株.

Taking High-bush Convair blueberry plantlets as materials,through impregnation and culture with colchicine of different concentrations,chromosome doubling was studied.From the morphology,physiology and biochemistry,anatomy and cytology were compared in order to determine the best treatment method and treatment quality concentration to induce polyploidy.The results showed that,in morphology and anatomy,the mean of blueberry the leaf length,leaf width,stem diameter and leaf thickness were significantly greater than CK after 0.5,2.0 and 4.0 mg/mL colchicine soaking for 1 d and 0.4 mg/mL colchicine culture for 10 d;in anatomical structure,0.5 mg/mL impregnated for 1 d and 0.4 mg/mL culture for 10 d,the stomatal density of blueberry becomes larger,low, oval,starch grains in guard cells reduced,and the nucleus becomes larger after 0.5,2.0 mg/mL soaking for 1 d and 0.4 mg/mL colchicine impregnated culture for 10 d were significantly larger nuclear;in the physiological indexes,0.5 mg/mL impregnated for 1 d significantly increased SOD activity of blueberry,colchicine soaking for 1 d and 4.0 mg/mL could significantly improve soluble protein content,the latter also significantly increased chlorophyll a content.Thus,after 10 d culture 0.5 mg/mL impregnated for 1 d and 0.4 mg/mL,the possibility of the occurrence of the blueberry plant polyploidy variant of the maximum,but need field identification of follow-up to ultimately determine the polyploid plants.
