This research was to evaluate the effects of culture filtrates pathogenic fungi on seed germination and seedling indices Chrysophyllum albidum (G.Don). The experiment carried out at Mycology Unit, Department Forestry Environment, Rivers State University, Nkpolu-Oroworkwo laid in a Completely Randomized Design (CRD) treatment replicated twenty times mean value separated using Duncan Multiple Ran...

Crop monitoring is critical for sustaining agriculture, preserving natural resources, and dealing with the effects of population growth climate change. The Sentinel missions, Sentinel-1 Sentinel-2, provide open imagery at a high spatial temporal resolution. This research aimed (1) to evaluate profiles derived from Sentinel-2 time series data in deducing dates phenological stages wheat germinati...

Plant growth promoting rhizobacteria (PGPRs) are a group of bacteria that can actively colonize plant roots and can modulate plant growth. The present study was aimed to investigate the effects of three PGPRs strains designated as Pseudomonas fluorescens (PF23) and P. putida (PP-41 and PP-159) on seed germination features including germination percentage (GP), mean time germination (MTG), germi...

Germination experiments with specific germination mutants of Bacillus subtilis, including a newly isolated mutant affected in pressure-induced germination, suggest that a pressure of 100 MPa triggers the germination cascades that are induced by the nutrient germinant alanine (Ala) and by a mixture of asparagine, glucose, fructose, and potassium ions (AGFK), by activating the receptors for alani...

drought resistance is a very important characteristic needed for plant survival especially at germination stage, in arid and semi-arid lands. phosphatase enzymes are widely found in plants. these enzymes are responsible for dephosphorylation of organic phosphate and altering it to mineral phosphate. germination experiments were conducted in two bread wheat cultivars (sardari and alvand) under s...

Germination timing influences plant fitness, and its sensitivity to temperature may cause it to change as climate shifts. These changes are likely to be complex because temperatures that occur during seed maturation and temperatures that occur post-dispersal interact to define germination timing. We used the model organism Arabidopsis thaliana to determine how flowering time (which defines seed...

Under changing climate, abiotic stresses especially salinity have posed serious threats to modern crop production systems of staple crops and chemo-priming with salicylic acid offers a promising remedy. The present study aimed at ameliorating the adverse effects salt stress through optimization (SA) for two bread wheat genotypes (DZ17-1 Empire Plus). trial was comprised different SA levels incl...

Seed germination is a crucial stage in the life history of a species because it represents the pathway from adult to offspring, and it can affect the distribution and abundance of species in communities. In this study, we examined the effects of phylogenetic, life history and environmental factors on seed germination of 134 common species from an alpine/subalpine meadow on the eastern Tibetan P...

Giant foxtail (Setaria faberi) seeds differ in requirements for germination. Variable germinability arises during seed development under the influence of genotype, environment and parent plant. Giant foxtail seed germination has been shown to be regulated by independent asynchronous or dependent synchronous action of seed structures. To gain better insight into the process, germination was divi...
