From immature young fruits of Ziziphus mauritiana and Aegle marmelos gibberellin-like factors were isolated. The factors a1, a2, a3, and a4 of Ziziphus were similar to gibberellins A1, A3, A9, and A4. The factors x1, x2, x3 isolated from Aegle marmelos behaved similarly to gibberellins A1, A3, and A9on paper, thin layer, and silicic acid, celite column chromatographic techniques. In both fruits peak gibberellin activity occurred during the early period of fruit growth and decreased during rapid fruit growth. The possible significance of the finding is discussed in view of fruit development. © 1985, Gustav Fischer Verlag, Stuttgart. All rights reserved.

Endogenous Gibberellins in Developing Fruits of Ziziph us mauritiana Lam. and Aegle marmelos Correa.

Journal of Plant Physiology

Following ion‐exchange, Sephadex LH‐20 and paper chromatography of the methanolic extracts of young, developing fruits of Aegle marmelos Correa, cytokinin‐like activity in the soybean callus assay was detected in six fractions. Of the four butanol‐soluble compounds, two were tentatively identified as zeatin and zeatin riboside, and the others as zeatin glucoside and zeatin riboside glucoside. The major cytokinino of the butanol‐insoluble fraction is probably zeatin nucleotide. The levels of compounds with cytokinin‐like activity were high during the early phase, and low in the subsequent period of fruit growth. The activity resembling that of cytokinin glucoside increased with maturation of the fruit. The content of free cytokinins in the fruits was more than that released from the tRNA.

A cytokinin complex from the developing fruits of Aegle marmelos

Developing fruits of jujube, Ziziphus mauritiana Lam., contain 2 cytokinin-like compounds, the activities of which were tested by the soybean callus test. One of them appeared to be zeatin, and this was confirmed by its behaviour in paper and column chromatography, coupled with various physicochemical tests. © 1981.
