Abstract

Abstract: Trichosanthes cucumerina L. (Cucurbitaceae) is a traditional fruit vegetable grown by family farmers in the Amazon. This study aimed to evaluate seed maturation as a function of age and fruit morphological characteristics, and the effect of different temperatures on seed germination of accessions of the species. A completely randomized design was adopted in the maturation study, with five treatments (fruit age: 20, 30, 40, 50, and 60 days after anthesis - DAA) and four replications. Seed quality was evaluated through dry mass, water content, germination, and vigor variables, while the fruits were evaluated for physical characteristics and the number of seeds. A completely randomized design in a 3 (temperatures: 20, 25, and 30 °C) x 7 (accessions: PIN I, PIN II, TSA, MAO, UTB, ITA, and IMI) factorial scheme, with four replications was adopted in the study of germination temperatures. Seed quality was evaluated using germination and vigor tests. Seeds reach physiological maturity around 50 DAA. The fruits are partially or completely orange or reddish-orange in color at that time. The temperature of 30 °C favored the seed germination process, resulting in a higher percentage and germination rate.

瓜蒌种子的成熟和萌发

摘要:黄瓜Trichosanthes cucumerina L.(葫芦科)是亚马逊地区家庭农民种植的传统水果蔬菜。本研究旨在评价种子成熟度随年龄和果实形态特征的变化，以及不同温度对种子萌发的影响。成熟研究采用完全随机设计，5个处理(果龄:开花后20、30、40、50和60 d - DAA)， 4个重复。通过干质量、含水量、发芽率和活力等指标评价种子质量，通过物理特性和种子数量评价果实质量。采用发芽试验和活力试验评价种子品质。种子在50 DAA左右达到生理成熟。当时的果实部分或完全呈橙色或红橙色。30℃的温度有利于种子萌发，萌发率和发芽率较高。

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.
