After-ripening is the mechanism by which dormant seeds become nondormant during their dry storage after harvest. The absence of free water in mature seeds does not allow detectable metabolism; thus, the processes associated with dormancy release under these conditions are largely unknown. We show here that sunflower (Helianthus annuus) seed alleviation of dormancy during after-ripening is assoc...

Introduction In a recent paper NOGuCHI (2) described histological studies made on the structure of Russian sunflower leaves grown from seeds irradiated at the stage of incipient germination, with hard, or short wave-length, x-rays. This paper describes a similar study in which the seeds used were dormant soy beans and the radiation was soft, or long wave-length, x-rays generated by a gas x-ray ...

The biological activity (contact and contact-digestive toxicity, repellent fumigant effects, effect on the insect’s development life cycle parameters) of industrial hemp (Cannabis sativa L.) ethanolic extract was assessed against Plodia interpunctella, most destructive storage pest sunflower. Additionally, study aimed to examine phytotoxic in order assess its potential as a sunflower grain prot...

Abstract Biologically active substances (BASs), including plant phytohormones-regulators of growth and development, are becoming increasingly important in agriculture activities. Their use allows to better realize the genetic potential crops, increase resistance plants stress factors biotic abiotic nature, as a result yields improve quality. In this research, it was aimed at researching effect ...

The article presents statistical and calculated indicators on the volumes of oilseeds cultivation, effect mineral fertilization soils during cultivation intensity intake heavy metals in them is investigated. An analysis Vinnytsia region showed that their total sown area as 2021 was 351.5 thousand/ ha, which 81.6% - sunflower, 17.7% winter rape 0.6% spring rapeseed. production sunflower seeds Vi...

The monitoring of grain and seeds characteristics is fundamental to maintain postharvest quality. Grain mass changes through CO2 levels can reduce the product deterioration by anticipating actions This study aimed develop a system in stored grains/seeds analyze its efficiency. analysis was performed four crop species (brachiaria, sunflower, corn, soybean) with different water content sanity con...

The objective of this study was to determine the major antioxidants and antioxidant activity in different fractions (skin, seeds and pulp) of three tomato cultivars (Excell, Tradiro and Flavourine) grown under hydroponic conditions in a commercial greenhouse in New Zealand. It was found that the skin fraction of all cultivars had significantly (p < 0.05) higher levels of total phenolics, total ...

In a semi-arid environment, the main challenge for crop production is water limitation in space and in time. Considered as appropriate tools, models are used to evaluate the effects of water deficit on crop productivity for better irrigation planning and sustainable yield. The AquaCrop model was tested using data collected during a 4-year experiment on soybean (Glycine max L. Merril) and s...
