Mechanization and simplification are inevitable trends in agriculture production to decrease input demands and simultaneously improve resource use efficiency. Dry direct-seeded rice is a resource-saving cropping system and has been considered as a replacement for traditional transplanted rice. However, the poor establishment of dry direct-seeded early rice, primarily induced by chilling stress,...

Many biologists studying environmentally induced parental effects have indirectly suggested that the parental environment alters seed mass by altering the amount of endosperm or embryo tissue in the seed. We tested this hypothesis by measuring the effects of parental temperature on total seed mass, seed coat mass, and embryo/endosperm mass in offspring of Plantago lanceolata. Parental temperatu...

Small heat shock proteins (sHSPs) function as ATP-independent molecular chaperones, and although the production and function of sHSPs have often been described under heat stress, the expression and function of sHSPs in fundamental developmental processes, such as pollen and seed development, have also been confirmed. Seed germination involves the breaking of dormancy and the resumption of embry...

to study seed dormancy and the after-ripening period in barley genotypes (57 dutch genotypes and two iranian cultivars (gorgan and valfair)), an experiment of randomized complete block design (two replications) was conducted at the research farm of collage of agriculture and natural resources, university of tehran in 2004-2005. in the growing stage of zgs92, panicle was collected. the percentag...

there are several methods to increase crops yield, including use of high quality seeds. seed priming is a simple and low-cost method to increase seed quality, if be done right, will lead to increasing plant performance and yield. seed priming treatment applied before planting to enhance germination parameters, seedling establishment and etc. primed seeds get some physiological and biochemical c...

Cadmium (Cd) is considered one of the most toxic heavy metals to living organisms, being very persistent in soil and non-biodegradable, thus posing a long-term hazard plants humans. In recent years, application different molecules at seed level, known as chemical priming, has been studied method improve stress tolerance plants. present study, we tested effect hydro-priming proline priming lettu...

BACKGROUND AND AIMS Ecotypic differentiation has been explored in numerous plant species, but has been largely ignored in the Orchidaceae. Applying a specific germination protocol for widespread seed sources may be unreliable due to inherent physiological or genetic differences in localized populations. It is crucial to determine whether ecotypic differentiation exists for restoration and conse...

Seed priming has been suggested to improve germination performance under temperature or water stress. The objective of this study was to develop an optimal osmopriming protocol for spinach (Spinacia oleracea L. cv. Bloomsdale) seeds and examine its effect on the germination performance at suboptimal and supraoptimal temperatures, and under water stress. Standard germination tests at optimal ger...

Priming of legume seeds before sowing was performed by Roman farmers in order to increase the germination rate and synchronize germination, as reported naturalist Gaius Plinius Secundus. Several centuries later, this technique is still used for a wide range species. However, measure be successfully production, it necessary find solution successful storage primed seeds. The potential soybean det...
