Seeds consist of encapsulated plant embryos in a highly resistant and desiccated state. Seeds enhance plant fitness by allowing plants to withhold their growth until the appearance of appropriate environmental conditions. Thereupon, seeds germinate, allowing the resumption of the plant’s life cycle. However, protection and propagation is not expected per se to confer fitness without germination...

Seed germination is the most important transitional event between early stages in the life cycle of spermatophytes and understanding it is crucial to understand plant adaptation and evolution. However, so far seed germination of phylogenetically closely related species has been poorly investigated. To test the hypothises that phylogenetically related plant species have similar seed ecophysiolog...

This investigation was carried out to improve the germination percentage and alkaloid 1 production in M seeds (irradiated seeds with 50, 80, 110 and 150 Gy) of Atropa belladonna L. by using and different concentrations of gibberellic acid (20,40,60,80,100 and 120 ppm). There was an increase in seed germination percentage by increasing gamma-ray doses until 150 Gy which gave 3 decrease in seed g...

The present investigation was carried out to study the induced mutagenesis of EMS (Ethyl methane sulphonate) on the seed germination, seedling survival and LD50 value of Catharanthus roseus. The seeds of Vinca rosea were treated with different concentration of EMS viz., 5, 10, 15, 20, 25, 30, 35, 40, 45 and 50 mM. The untreated seeds were taken as control. The EMS treated and control seeds were...

low seed germination and seedling emergence is one of the main problems in saline areas. seed priming technique has been known as a challenge to improve germination and seedling emergence under different environmental stress. the objective of this research was to evaluate the effect of seed priming with gibberellin, nacl and water on seed germination and seed reserve utilization and germination...

Seed germination is a key developmental transition that initiates the plant life cycle. The timing of germination is determined by the coordinated action of two phytohormones, gibberellin and abscisic acid (ABA). In particular, ABA plays a key role in integrating environmental information and inhibiting the germination process. The utilization of embryonic lipid reserves contributes to seed ger...

Silvereyes, Zosterops lateralis Latham, commonly feed on kiwifruit rejected for export and either stored in open bins at packhouses or in piles ready to be fed to livestock, and may play a role in the spread of wild kiwifruit in native and exotic forest in the Bay of Plenty, New Zealand. We determined the germination rate and percentage germination of Actinidia chinensis Planch. seed sown (1) a...

in order to study the effects of on-farm seed priming and sowing date on germination percentage, germination speed, and some growth indices of three soybean cultivars, a field experiment was carried out in three replications using a split plot factorial in a randomized complete block design. main plots were representative of two sowing date (5th and 21th of may), while subplots included combina...
