“…On this sowing date the seed growth period was exposed to high temperatures (Szemruch et al, 2014) which may have affected seed vigor at harvest time. Similar effects of growing field conditions on seed vigor have been observed in soybean, wheat, barley and groundnut (Egli et al, 2005;Samaraha and Alqudaha, 2011;Hasan et al, 2013;Sharma et al, 2013). In addition, a significant genotype by environment interaction was observed for EC values when G1and G2 grown on all sowing dates were evaluated by ANOVA (data not shown).…”

Electrical Conductivity (EC) is a promising vigor test since it produces fast laboratory results. In sunflower, the leakage of electrolytes from the pericarp may interfere with exudates from embryo tissues. The aims of this work were (1) To determine the utility of the EC test using dehulled (without pericap) sunflower seeds to evaluate the vigor in different genotypes, exposed to contrasting seed filling period and storage conditions, (2) To explore the relationship between EC and germination values near post harvest and across storage period and (3) To propose ranges of vigor through EC, so as to categorize sunflower seeds lots. Seeds of commercial hybrids differentiated by acid composition (high and standard oleic acid), exploring contrasting seed filling period and storage conditions, were evaluated by EC, Tetrazolium (TZ-V) and Germination (G), near post harvest time and during storage period (1, 5, 9, 13 and 19 months). An independent set of 18 genotypes, stored during 1-108 months, were also analyzed for EC and G. Electric conductivity in dehulled seeds was effective to identify vigor differences of genotypes in different seed filling period and storage conditions. A general relationship between the loss of germination and vigor was established for sunflower. The ranges of vigor based on EC proposed for sunflower seeds classification were <70 µs cmG 1 gG 1 for high, 70-110 µs cmG 1 gG 1 for intermediate and >110 µs cmG 1 gG 1 for low vigor levels. It is the first report based on EC ranges to categorize the seed vigor of sunflower seeds lots.

“…Great importance in the success of seed protection is the correct timing of fungicide treatment. Thus, seed disinfectants are commonly used in packing material deposited in the late summer or autumn, and fungicides are used for spraying perennial plants during dormancy in late fall, winter or early spring, as they can be dangerous to growing plants [32], [33]. Currently, in addition to the use of the described methods to prevent spoilage during storage, fruit treatment by fungicides is also practised [34].…”

The establishment of safe and effective methods for controlling fungal diseases is an urgent issue in agriculture and forestry. Fungicide research has provided a wide range of products with new modes of action. Extensive use of these compounds in agriculture enhances public anxiety due to the harmful potential for the environment and human health. Moreover, the phytotoxic effects of some fungicides are already recognized but still little is known about their influence on the photosynthetic apparatus and plant physiology. This review provides an understanding of the mechanisms of action of fungicides, mechanisms of fungicide resistance development, and the phenomenon of phytotoxicity.

“…Therefore, there is always a demand to enhance its production. Nonetheless, wheat crop in ricewheat or cotton-wheat cropping systems is often exposed to high temperature during grain filling stage and produce seed of poor quality and less vigor (Hasan et al, 2013). Delayed planted crop experience poor crop stand if inadequate soil moisture or adverse soil conditions prevails under fields that usually reduces germination and seedling growth and substantially reduced crop harvest (Farooq et al, 2008;Yasmeen et al, 2013a).…”

The effect of exogenously-applied Moringa (Moringa oleifera Lam.) leaf extract (MLE) on delaying the leaf senescence and modifying the source-sink relationship in wheat (Triticum aestivum L.) was studied. MLE (3.3%) was used as seed osmopriming (SP) and/or foliar spray (F), and water as hydropriming (HP). Among seedling attributes, improved shoot and root lengths, leaf and root scores were found for SP and/or F treatments. Increase or decrease in stem dry weight simultaneously with grain dry weight might contribute for soluble stem reserves towards grain weight as showed by delayed leaf senescence in SP or combined SP+F treatment. The SP and F treatments had also earlier spike emergence and anthesis stage. Plant height, tillers number, biological and grain yields per plant were also recorded highest for SP+F treatment followed by SP. Thus, MLE being rich in zeatin, a cytokinin maintained the green photosynthetic area and enhanced grain filling that might contributed towards improved grain yield when applied as SP or in combination with foliar.
