AbstractThis study was undertaken to better understand the probable mechanisms of salt stress tolerance induced by seed priming of salicylic acid (SA) in barley. The barley seeds were pre-soaked by SA or water and then sown under different saline watering regimes including 0.62 (tapwater), 5, 10 and 15 dS m-1 in petri dishes and trend of water absorbing, seedling growth, germination rate and pe...

humic substances as an active part of soil organic maters can improve germination and seedling properties, plant establishment and plant growth. in order to study the effects of different concentrations of humic and fulvic acids on germination and seedling properties of two varieties of triticale (triticosecale hexaploide lart.), a factorial experiment based on a completely randomized design wi...

Scatter hoarding of seeds by animals contributes significantly to forest-level processes, including plant recruitment and forest community composition. However, the potential positive and negative effects of caching on seed survival, germination success, and seedling survival have rarely been assessed through experimental studies. Here, I tested the hypothesis that seed burial mimicking caches ...

Exogenous glucose delays seed germination in Arabidopsis thaliana not only in wild type (WT), but also in a number of mutants in hormone signalling pathways. This study demonstrates that the ABA Insensitive 3 (ABI3) gene in the ABA signalling pathway and the RGA-like 2 (RGL2) and SPINDLY (SPY) genes in the GA signalling pathways all play important roles in the glucose-induced delay of seed germ...

Definition, analysis, and certification of biochar quality are crucial to the agronomic acceptance of biochar. While most biochars have a positive impact on plant growth, some may have adverse effects due to the presence of phytotoxic compounds. Conversely, some biochars may have the ability to adsorb and neutralize natural phytotoxic compounds found in soil. We evaluated the effects of biochar...

An investigation was initiated to examine the effects of carbon soot collected from exhaust tube of 15 years old petrol and diesel operated vehicles on gram seed germination and biochemical changes of seedling. In view of the widespread cultivation of gram seed in India and long-term impact of black carbon is the warming of the atmosphere as per the recommendation of IPCC (2007). Black soot wer...

Currently biological invasions are considered one of the world's most serious conservation problems. Ligustrum lucidum is the most abundant exotic tree in secondary forest patches of montane forests of NW Argentina. We studied the determinants of success of the early stages of its life cycle in distinct habitat types, with the hope of identifying vulnerabilities that could be exploited to contr...
