Abstract

Abstract: Global efforts to restore ecosystems have increased the demand for seeds of native species, both from tree-shrub and herbaceous strata. However, little is known about seed ecology or germination of many herbaceous species from the Brazilian Caatinga. Neoglaziovia variegata (caroá) is a bromeliad endemic to this biome and has great ornamental and fiber production potential. This study aimed to morphologically characterize N. variegata fruits and seeds and to evaluate its germination-related parameters. To do so, the morphometry of bunches, fruits, and seeds was investigated, and seeds were assessed for physiological quality at two maturation points and light response. The morphometric measurements showed normal distributions and a wide dispersion from the central values. Therefore, there is genetic variability among individuals of the same population. The seeds showed high germinability, and fruits had an average size of 8.5 x 9.4 cm, whose color (green or purple) did not influence their physiological quality. The seeds of N. variegata are positive photoblastic, and their germination reaches maximum values after two weeks in the presence of light.

新紫果种子形态计量学特征及功能性状研究。

摘要:全球生态系统恢复的努力增加了对本地物种种子的需求，包括乔灌木和草本地层。然而，人们对巴西卡廷加许多草本植物的种子生态学和发芽情况知之甚少。Neoglaziovia variegata (carotta)是该生物群系特有的凤梨科植物，具有很大的观赏和纤维生产潜力。本研究旨在对杂交莲果实和种子进行形态学表征，并对其发芽相关参数进行评价。为此，研究人员对束、果实和种子的形态测定进行了研究，并对种子在两个成熟点的生理品质和光响应进行了评估。形态计量学测量显示正态分布，与中心值有较大的离散度。因此，同一种群的个体之间存在遗传变异。种子萌发能力强，果实平均大小为8.5 x 9.4 cm，果实颜色(绿色或紫色)不影响其生理品质。杂交种的种子具有正光芽性，在光照条件下2周萌发达到最大值。

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.
