Alpine plants are considered to be particularly vulnerable to climate change and related extreme episodes, such as heat waves. Despite growing interest in the impact of heat waves on alpine plants, knowledge about their effects on regeneration is still fragmentary. Recruitment from seeds will be crucial for the successful migration and survival of these species and will play a key role in their...

BACKGROUND AND AIMS Selective pressures exerted by agriculture on populations of arable weeds foster the evolution of adaptive traits. Germination and emergence dynamics and herbicide resistance are key adaptive traits. Herbicide resistance alleles can have pleiotropic effects on a weed's life cycle. This study investigated the pleiotropic effects of three acetyl-coenzyme A carboxylase (ACCase)...

BACKGROUND: Seed aging is an important problem in developing countries which seeds stored in inappropriate condition. OBJECTIVES: Current research was carried out to study the effect of seed aging on quantitative parameters of wheat seeds (Chamran cultivar). METHODS: Experiment was carried out based on randomized complete block desi...

in order to study the cardinal temperatures of three weeds henbane (hyoscyamus niger l), aconite (aconitum napellusl l.) and hemp (cannabis sativa l.) at seven levels of temperatures (5, 10, 15, 20, 25, 30 and 35 °c), an experiment was carried out in completely randomized design with 3 replications and factorial experimental arrangement in weeds research laboratory, faculty of agriculture, ferd...

Interation of cyclic AMP with a profoundly changing pattern of specific binding proteins was shown during aerobic germination of sporangiospores from the fungus Mucor racemosus. 32P-labeled 8-azido-cycli AMP, an analogue of cyclic AMP that forms a covalent linkage with the binding proteins under u.v. light, was used as the ligand. Binding proteins carrying this photoaffinity label were separate...

This study examined if pre-germination altered the water content and water activity, contents of phytate, total phenolic, (±)-catechin, quercetin and total antioxidant capacity of almond  (Prunus dulcis)kernel. Raw almond kernels were submerged for 15 hours in water, 0.02 mol dm-3 phosphate buffer solution (pH 5.0) and 0.02 mol dm-3 phosphate buffer solution (pH 7.0) at 25 and 40ºC, respectivel...

Intense selection for specific seed qualities in winter oilseed rape breeding has had an inadvertent negative influence on seed germination performance. In a panel of 215 diverse winter oilseed rape varieties spanning over 50 years of breeding progress in winter-type rapeseed, we found that low seed erucic acid content and reduced seed glucosinolate content were significantly related with prolo...

introduction: seed germination is an important stage in the life history of plant affecting seedling development, survival, and population dynamics. germination begins with seed, water uptake and terminates with the elongation of the embryonic axis from the seed coat. germination and seedling emergence are the most important phonological development stages in pigweed and have a vital role in it...

Fungal infections have become a concern for health professionals, and the emergence of resistant strains has been reported for all known classes of antifungal drugs. Among the fungi causing disease, we highlight those that belong to the genus Aspergillus. For these reasons, the search for new antifungals is important. This study examines the effects of a coumarin derivative, 4-acetatecoumarin (...

to evaluate the effects of accelerated aging and cold stress on seed germination and seedling growth indices in five oilseed rape cultivars (hyola330, hyola401, hyola420, syn3 and pr401/15e), an experiment was carried out in a completely randomized design of three replications. results indicated that the cultivars were significantly different in germination percentage, seed vigour, germination ...
