Abstract
Abstract This study explores the propagation of Frangula sphaerosperma, a species relevant for ecological restoration, by characterizing its seed and biometric traits (length, width, and shape indices) and evaluating germination at 20, 25, 30 and 35 °C. Germination percentage, germination speed index, average germination time, and seedling normality (defined by the presence of essential structures, such as well-formed roots and expanded leaves) were assessed. Seed traits were obtained using image-based measurements with ImageJ®. Seeds showed low moisture content (10.8%) and were classified as small and circular, with a thousand-seed weight of 20.04 g, corresponding to 49,888 seeds kg-1. Germination was similar between 20 and 30 °C (27.3- 33.8%); however, 25 °C optimized seedling quality, providing the highest percentage of normal seedlings (12%) and the shortest average germination time (11 days). Temperatures above 30 °C reduced germination and seedling formation, indicating sensitivity to heat stress and supporting nursery production at 25 °C.
A study of seven Stylosanthes seabrana genotypes was conducted during the 2022-23 kharif and rabi season at ICAR-Indian Grassland and Fodder Research Institute, Dharwad. Additionally, the effect of dormancy-breaking treatments on seed quality was assessed at the Seed Testing Lab of NSP/BSP Unit, University of Agricultu...

Generative propagation of Mucuna bracteata is hindered by its thick seed coat, which causes seed dormancy. This study aimed at evaluating viability and vigor of M. bracteata due to pre-treatments. A completely randomized design was used to test four pre-treatments: no treatment (Kon), soaking in warm water (50°C) for 2...

Cactus Echinocereus cinerascens is a cactus of ecological and cultural importance in the Mexican Plateau; however, fundamental knowledge regarding its seed germination remains scarce. This study evaluated germination response under different temperatures (10, 18, 25, and 30 °C) and water potentials (well-hydrated, -0.5...

ABSTRACT: This study aimed to determine seed germination characteristics of citron (Citrus medica) and improve its germination. Citron was used as materials to observe its characters. Effects of seed coat removal, seed size and fruit maturity on citron seed germination were investigated. The findings indicated that the...
