Application of chemical substances as stress pre-treatment factors may positively influence androgenetic responses in cereal and other crops. AgNO is an anti-ethylene compounds that played a significant role in combination with other chemicals for anther culture responses in cereal and other crop plants. For this study two local wheat cultivars . Kheri and Akbar were considered to evaluate the effect of AgNO and to optimize the suitable doses of plant growth regulators, amino acids and sucrose that supplemented in MS medium. Data were recorded on the basis of embryoids induction, regenerated green and albino plants. The results clearly stated that anther culture responses and its major outcomes on regeneration significantly increased with suitable dosages of chemicals. The most noteworthy increases embryo like structures and regenerated green plants accomplished by utilizing the combined effect of AgNO (50 mg/l) and as plant growth regulators IAA (1.0 mg/l) + kinetin (0.5 mg/l). Best embryo like structures (79.17%) and green plants (33.33%) were recorded in Kheri. The results clearly stated that reducing albinism and increasing embryos induction and green plants 50-75 mg/l silver nitrate along with optimum doses of IAA and kinetin showed very effective results in wheat.
将化学物质用作胁迫预处理因子可能会对谷类作物和其他作物的雄核发育反应产生积极影响。硝酸银是一种抗乙烯化合物,在与其他化学物质结合用于谷类作物和其他作物的花药培养反应中发挥了重要作用。在本研究中,选用了两个当地小麦品种——凯瑞和阿克巴,以评估硝酸银的效果,并优化添加到MS培养基中的植物生长调节剂、氨基酸和蔗糖的合适剂量。根据胚状体诱导、再生绿色植株和白化植株记录数据。结果清楚地表明,使用合适剂量的化学物质可显著提高花药培养反应及其再生的主要结果。利用硝酸银(50毫克/升)与植物生长调节剂吲哚乙酸(1.0毫克/升)+激动素(0.5毫克/升)的联合作用,获得了最显著的类胚结构增加和再生绿色植株。在凯瑞品种中记录到最佳的类胚结构(79.17%)和绿色植株(33.33%)。结果清楚地表明,在小麦中,50 - 75毫克/升的硝酸银与最佳剂量的吲哚乙酸和激动素一起使用,可有效减少白化现象,增加胚诱导和绿色植株。
