The occurrence of 2 gibberellin-like substances was demonstrated in the developing banana fruit, Musa sapientum, Linn. Chemical and biological evidence led to the tentative identification of the 2 compounds as GA(7) and GA(x) (previously isolated from citrus fruits). Support for such identification was obtained from thin layer chromatography, gradient elution column chromatography, spectrofluorometry, the dwarf maize test, and the cucumber hypocotyl test. Significance of the GA(x) -designated compound increased since it is believed to occur in the fungus Fusarium moniliforme, Sheld. in addition to 2 different species of higher plants. It does not resemble any of the known gibberellins as far as chromatography is concerned.
在发育中的香蕉果实（Musa sapientum, Linn.）中证实存在两种类赤霉素物质。化学和生物学证据初步鉴定这两种化合物为GA(7)和GA(x)（此前从柑橘类果实中分离得到）。通过薄层色谱法、梯度洗脱柱色谱法、荧光分光光度法、矮生玉米试验和黄瓜下胚轴试验，为上述鉴定提供了支持。被命名为GA(x)的化合物的重要性增加了，因为据信它除了在两种不同的高等植物中出现外，还存在于串珠镰孢菌（Fusarium moniliforme, Sheld.）中。就色谱分析而言，它与任何已知的赤霉素都不相似。
