Effects of cold plasma treatment on soybean (Glycine max L. Merr cv. Zhongdou 40) seed germination and seedling growth were studied. Seeds were pre-treated with 0, 60, 80, 100 and 120 W of cold plasma for 15 s. Results showed that plasma treatments had positive effects on seed germination and seedling growth, and treatment of 80 W had the highest stimulatory effect. Germination and vigor indice...

Temperature and relative humidity in combination cause rapid decline in seed quality during storage. To maintain the seed quality in storage a number of physical and chemical treatments are used. Magnetic field treatment is one such physical treatment practiced to improve the seed quality. An experiment was conducted to investigate the efficacy of this treatment to improve the storability of se...

Seeds of east Australian Grevillea species germinate in response to fire-related cues such as heat and smoke. The seed coat is responsible for dormancy in G. linearifolia: a possible dormancy mechanism is the existence of barriers to diffusion of large molecular weight compounds in the seed coat. Such internal barriers are known to be involved in the dormancy of fire-responsive seeds overseas e...

1 Faculty member,Agricultural and Natural Resources Research Center of Yazd, Yazd, Iran ABSTRACT. Seed germination and seedling growth are critical stages in the life cycle of a plant, especially under adverse abiotic stresses. Seed germination negatively affected by stress conditions. Seed priming techniques have been used to increase germination characteristics and improve germination uniform...

Elatine L. contains ca. 25 small, herbaceous, annual species distributed in ephemeral waters in both hemispheres. All species are amphibious and characterized by a high degree of morphological variability. The importance of seed morphology in Elatine taxonomy has been emphasized by many authors. The degree of seed curvature and seed coat reticulation have been traditionally considered very impo...

Seed priming is widely recognized as a significant phenomenon for synchronizing germination and enhancing the vigor of seeds. Seeking importance priming, influence magnetic treatments in overall performance plants cannot be undermined well. In present study, seeds Pisum sativum L. Plantago ovata Forssk. were primed with essential Plant Growth Regulators (PGRs) such as; Gibberellic acid (GA3), P...

Purpose. The objective of this study was to evaluate the morphological parameters Lycium spp. seeds from collections in M. Hryshko National Botanical Garden (NBS) NAS Ukraine. Methods. Cultivars and varieties three species (Lycium barbarum, L. chinense, truncatum) were studied period 2016 till 2019. following morphometric measurments conducted: weight, length, width index shape. Basic statistic...

From a plant's perspective, the difference between a seed predator and a seed disperser should be straightforward: attract animals that will disperse seeds and defend seeds from potential predators. Unlike pulp-eating frugivores, seed predators regularly encounter diverse plant protective mechanisms. The purpose of this paper is to examine feeding constraints, morphological adaptations, and the...

BACKGROUND AND AIMS Germination is very important for plant establishment in arid regions. The strategies taken by halophytes during the seed germination stage to adapt to saline environments in an arid zone were investigated in Suaeda physophora (euhalophyte), Haloxylon ammodendron (xero-halophyte) and Haloxylon persicum (xerophyte). METHODS Seeds of S. physophora, H. ammodendron and H. pers...
