摘要

摘要:本试验旨在研究山核桃果实发黑对山核桃果实和种子形态特征、含油量、脂肪酸含量、种子发芽率及生理特性的影响。在5℃干湿贮藏0 d、20 d、40 d、60 d和80 d条件下进行萌发试验。黑色果实的果实质量、百粒重、果实含水量、种子含油量和不饱和脂肪酸中的油酸含量显著低于红色果实(P <0.05)。湿贮藏条件下黑色果实种子的发芽率高于红色果实，且随着贮藏时间的延长，黑色果实的丙二醛含量降低。结果表明，黑果不应随意丢弃，可根据使用目的选择果实的颜色。摘黑色果实用于物种繁殖，摘红色果实主要用于榨油。

Influence of fruit color on the oil quality and seed germination of Idesia polycarpa Maxim.

Abstract: The aim of this study was to investigate the effects of Idesia polycarpa fruit blackening on fruit and seed morphological characteristics, oil content, fatty acid content, seed germination rate and physiological properties. Germination tests were conducted under dry and wet storage at 5 °C for 0 d, 20 d, 40 d, 60 d and 80 d. The fruit mass, the 100-grain weight, the moisture content, the oil content of seeds and oleic acid in unsaturated fatty acids of black fruit are significantly lower than red fruit (P < 0.05). The germination rate of black fruit seeds was higher than red under wet storage and the malondialdehyde content of black fruits decreased with increasing storage time. Our results demonstrated that black fruits of I. polycarpa should not be discarded indiscriminately and that the color of the fruits can be chosen according to the purpose of use. Black fruits are picked for species propagation, while red fruits are mainly harvested for oil extraction.

期刊介绍： From 2017 the Journal of Seed Science (JSS) will circulate online version only. Original scientific studies and communications, not yet published or submitted to another journal for publication and written in Portuguese or English, will be accepted for publication. For manuscripts submitted in English, the authors should provide an adequated version. The SCIENTIFIC COMMUNICATION is a category of scientific manuscript which describes a technique, an equipment, new species or observations and surveys of limited results. It has the same scientific rigor as the “Scientific Articles” and the same value as a publication. The classification of a manuscript as a SCIENTIFIC COMMUNICATION is based on its content and scientific merit but it can be a preliminary study, simple and not definitive on a certain subject, with publication justified by its uniqueness and contribution to the area. The Editorial Board of the JSS may invite leading authors of recognized reputation to compose specific Review Articles covering topics of their specialization that will convey to the scientific community the state-of-the-art knowledge related to the specific theme.
