due to the use of secale montanum for different rangelands reclamation across the country, management of these ecosystems need to be aware of its ability to environmental stresses. this research investigated the effect of pollutant element of cu and pb on seed germination and growth of this species in laboratory. therefore, the effect of five treatments (control, 50, 100, 150, 200ppm) of pb (no...

the effect of electromagnetic field was examined on zinnia (zinnia elegans) seeds to enhance seed germination and early growth. the seeds were exposed to four magnetic strengths of 15, 100, 400 and 800 mt in four durations of 30, 60, 120 and 240 min. the experiments were carried out in two forms of laboratory germination and soil emergence. results showed that magnetic field application enhance...

Seeds with high vigor have strong resistance to various adverse environmental conditions. However, little is known about how seed affects the of seeds biotic stress. In this study, newly harvested that had and low vigor, achieved via an artificially accelerated aging treatment, were used in germination test after inoculation Fusariumgraminearum for 24 h. The results showed high-vigor seed-relat...

Drought is one of the major stress factors affecting growth and development plants, responsible for considerable crop yield losses worldwide. An experiment was conducted to compare three rice (Oryza sativa L.) varieties (BRRI dhan49, BRRI dhan71 dhan75) drought tolerance based on some parameters physiological status in germination stage. imposed by five levels polyethylene glycol (PEG) (0%, 10%...

Water-deficit stress poses tremendous constraints to sustainable agriculture, particularly under abrupt climate change. Hence, it is crucial find eco-friendly approaches ameliorate drought tolerance, especially for sensitive crops such as maize. This study aimed at assessing the impact of seed halo-priming on seedling vigor, grain yield, and water use efficiency maize various irrigation regimes...

The study on effects of seed provenance plant establishment index, seedling vigor index and speed germination Jatropha curcas L. was carried out during 2019 raining season, at Teaching Research Farm, Shehu Shagari College Education Sokoto, Nigeria. seeds were collected from different live hedges in the State, four local government areas each senatorial district. treatments consisted 16 accessio...

This study was conducted at the Gorgan University of Agricultural Sciences and Natural Resources farm, Iran, Golestan province with about 600 mm annual rainfall in order to evaluate the effect of different sowing dates on Azivash (Corchorusolitorius) seed quality, using a randomized complete block design with three replications on 2013. Treatments were four sowing dates such as May 5, ...

Drought stress diminishes seedling germination and vigor by reducing water uptake, inhibiting plant growth development. Most of the pulse growing areas are under rainfed ecosystems, which significantly reduces crop yield. Melatonin, a growth-regulating compound, is widely used to mitigate negative effects abiotic stresses in pulses. With this background, laboratory experiment was conducted stan...
