    • A composition and method to mitigate plant autophagy and/or apoptosis of newly developing cells in plants grown under environmentally stressful growing conditions, such as high temperature. Exogenous application of a cytokinin, preferably kinetin, to either the roots or the foliage (i.e., flowers and leaves) of plants has been discovered to overcome, or at least substantially mitigate, autophagy when applied during or just prior to flowering. Experimental results indicate that high temperature-induced autophagy, and subsequent new cell apoptosis, is the result of a deficiency of cytokinin in the plant tissues. The application of low concentrations of potassium together with the cytokinin appears to provide a synergistic effect by amplifying the effect of the cytokinin to lessen autophagy and increase crop productivity.
    • 用于减轻在环境胁迫生长条件如高温下生长的植物中新发育的细胞的植物自噬和/或细胞凋亡的组合物和方法。 已发现细胞分裂素(优选激动素)向植物的根或叶(即花和叶)外源性施用以克服或至少基本上减轻当在开花期间或之前施用时的自噬。 实验结果表明,高温诱导的自噬和随后的新细胞凋亡是植物组织中细胞分裂素缺乏的结果。 低浓度的钾与细胞分裂素一起的应用似乎通过扩大细胞分裂素的作用来减轻自噬和提高作物生产力来提供协同效应。
