Abstract

SummarySeasonal changes in the concentrations of indole-3-acetic acid (IAA) and abscisic acid (ABA) in the endosperm and integument of the ovule of Ginkgo biloba L. were analysed by GC-MS using [d5]-IAA and [d6]-ABA as internal standards. The concentration of IAA in the endosperm increased rapidly during the period of rapid growth, and was closely correlated with the growth rate of the ovule. The concentration of IAA in the integument was much lower than that in the endosperm, but also changed similarly. The concentration of ABA in the endosperm showed a peak after the cessation of rapid growth, and decreased during the fertilization period. The concentration of ABA in the integument also increased after the cessation of rapid growth, though slowly.

银杏胚珠发育过程中吲哚-3-乙酸和脱落酸浓度的变化

摘要以[d5]-IAA和[d6]-ABA为内标，采用气相色谱-质谱法分析了银杏胚乳和胚珠被中吲哚-3-乙酸(IAA)和脱落酸(ABA)浓度的季节变化。胚乳中IAA浓度在快速生长期迅速升高，且与胚珠的生长速率密切相关。被皮中IAA浓度远低于胚乳，但变化趋势相似。胚乳中ABA含量在快速生长结束后达到峰值，在受精期逐渐下降。在快速生长结束后，被皮中ABA的浓度也有所增加，但速度较慢。

期刊介绍： The Journal of Horticultural Science and Biotechnology is an international, peer-reviewed journal, which publishes original research contributions into the production, improvement and utilisation of horticultural crops. It aims to provide scientific knowledge of interest to those engaged in scientific research and the practice of horticulture. The scope of the journal includes studies on fruit and other perennial crops, vegetables and ornamentals grown in temperate or tropical regions and their use in commercial, amenity or urban horticulture. Papers, including reviews, that give new insights into plant and crop growth, yield, quality and response to the environment, are welcome, including those arising from technological innovation and developments in crop genome sequencing and other biotechnological advances.
