Abstract This study aimed to evaluate the effect of fruit maturation stages and pre-germination treatments with plant regulators on physiological quality seeds cv. BRS Mel do Cerrado. Two experiments were carried out, germination emergence, installed in a completely randomized design 3 x 2 factorial arrangement, three (1-partially ripe fruits; 2-fully fruits 3-senescent fruits) two (1. [GA4+7 +...

considering forage grass species, germination is one of the important stagesconcerning the growing stage that is often influenced by environmental stresses,particularly salinity and drought stresses. thus, this study aims to assess the effects ofsalinity and drought stresses on germination characteristics and seedling growth of desertwheatgrass, agropyron desertorum (fisch. ex link) schult. in ...

the present study was aimed to investigate the effects of titanium dioxide nanoparticles (nano-tio 2 ) on wheat ( triticumaestivum l.) plants cv. parsi. the experimental treatments included seven concentrations of nano- tio 2 (10, 100, 1000, 1200, 1500 and 1700 ppm nano-tio 2 and control (without any tio 2 ). the results showed that among the wheat germination indices, germination rate and weig...

To study the effects of chilling on dormancy breaking and the increased germination characteristics of Nepeta (germination percent and speed, seedling length, vigor index, wet and dry weight), a factorial experiment in a completely randomized design with 4 replications was implemented in a laboratory in 2014. Factor A was the chilling treatment in three levels (control, one-month and two-month ...

The objective of this paper was to evaluate the effect of nitric oxide (NO) as a protecting agent of sesame seeds submitted to different concentrations of cadmium. The treatments were: water (control), water increased by sodium nitroprusside (SNP) and other treatments regarding the concentrations of cadmium increased by SNP. The following determinations were done: germination, first count of ge...

Knowledge of plant response to salinity, especially at early growth stages, is critical optimizing crop production in salt-affected soils. In this paper we explore quantitatively the effectiveness seed pre-treatment lessen effects salinity on Borage (Borago officinalis L.) germination and subsequent seedling growth. Two independent experiments were conducted with nine levels five pre-treatments...
