Significant gibberellin-like activity has been detected in the 1000xg fraction of leaves of Brassica oleracea var. acephala (Canson kale) and Hordeum vulgare (cv. "Himalaya"). In kale and barley the qualitative pattern of activity found in the chloroplast fraction differs from that normally seen in total-leaf extracts. When expressed on a total chlorophyll or sample fresh-weight basis, approximately 16% of the gibberellin-like activity found in the leaf can be accounted for in the 1000xg or chloroplast fraction. The physiological implications of this finding are discussed.
在 Brassica oleracea var. acephala（大头菜）和 Hordeum vulgare（cv. “喜马拉雅”）叶片的 1000xg 级分中检测到显著的赤霉素样活性。在大头菜和大麦中，在叶绿体级分中发现的活性定性模式与通常在总叶提取物中观察到的模式不同。以总叶绿素或样品鲜重为基础表示时，在叶片中发现的赤霉素样活性的大约 16%可以用 1000xg 或叶绿体级分来解释。讨论了这一发现的生理意义。
