摘要

摘要/ Abstract摘要:光合色素尤其是叶绿素的含量对种子的品质、活力和贮藏性有重要影响。光合色素的测定以及与种子质量参数(如发芽和胚根出芽)的相关性，使色素含量作为种子质量的新指标成为可能。采用分光光度法测定了胡萝卜、芹菜、莳萝、欧芹和防风草等商品成熟种子提取物中光合色素的含量。叶绿素a、叶绿素b、β-胡萝卜素和叶黄素含量在蜂科不同种间和种内不同品种间存在差异。分光光度法是一种简便、快速、廉价的测定成熟种子中光合色素含量的方法。分别在72、96、120、144和168 h进行光合色素含量与标准萌发、萌发速度指数(GSI)和胚根出苗(RE)等种子质量参数的比较，根据光合色素含量与种子质量参数(GSI和RE)的相关性，筛选出叶绿素b和叶黄素含量，可作为种子质量的新标志。

Correlation of photosynthetic pigments content with indicators of seed quality in the seeds of carrot, celery, dill, parsley, and parsnip

Abstract: The content of photosynthetic pigments, especially chlorophylls, has a significant effect on the quality, viability, and storability of seeds. Determination of photosynthetic pigments together with the correlation with seed quality parameters, such as germination and radicle emergence, lead to the possibility of using the pigments content as a new indicator of seed quality. The photosynthetic pigments content was determined spectrophotometrically from extracts of commercial mature seeds of carrot, celery, dill, parsley, and parsnip. The content of chlorophyll a, chlorophyll b, β-carotene, and lutein varied among species of family Apiaceae and among varieties within species. Spectrophotometry was verified as easy, quick, and inexpensive method that can be used for the determination of photosynthetic pigments in mature seeds. The individual pigments content was compared to seed quality parameters such as standard germination, germination speed index (GSI), and radicle emergence (RE), which was carried out at 72, 96, 120, 144, and 168 h. Based on the correlation of photosynthetic pigments content with seed quality parameters (GSI and RE), chlorophyll b and lutein content were selected, and can be used as the new markers of seed quality.

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.
