Successful fruit set depends on several reproductive processes including pollen germination and tube growth processes. An experiment was conducted to determine the effects of temperature on pollen germination characteristics and to identify species/genotypic differences in Capsicum using the cumulative temperature response index (CTRI) concept. Pollen was collected from plants of seven genotype...

in order to study the effects of different levels of drought stress and plant growth promoting rhizobacteria on the germination indices of seeds harvested from wheat (tritium aestivum l.) cv. sayonz in the field treated with different levels of nitrogen, in controlled conditions, a factorial layout based on completely randomized design with three replications, was conducted. treatments included...

Hydrogen gas (H2), an important gaseous regulator, is involved in various plant growth and development processes. However, there have been few studies on the role of H2 seed germination. In this study, underlying mechanisms enhancing germination were investigated cucumber (Cucumis sativus L.). The results revealed that rate, germ length, index, vitality index exhibited a dose-dependent relation...

Sorghum (Sorghum bicolor L.) originated in the semi-arid tropics and generally is sensitive to low-temperature stress. Chilling stresses include low temperature (below 20 °C) and freezing injury (below 0 °C). In this study seed germination and seedling growth of three sorghum genotypes (KFS1, KFS2 and Speedfeed) were examined under four temperature regimes (35/15, 20/10, 13/10 and 11/8) conditi...

there is substantial diversity in achillea biebersteinii plants in iran. it has considerable different biological activities including antibacterial, antifungal, antioxidant, insecticidal, herbicidal and wound healing. research improvement for medicinal plants depends on the available genetic diversity. the assessment of genetic variability could increase the information for breeding programs. ...

In this study, the biocontrol efficacies of 14 endophytic bacterial strains were tested against Blumeria graminis f. sp. tritici (Bgt) in pot experiments under greenhouse conditions. Bacillus subtilis strain E1R-j significantly reduced disease index and exhibited the best control (90.97%). When different formulations of E1R-j were sprayed 24 h before Bgt inoculation, fermentation liquid without...

Hydrothermal carbonization (HTC) of microalgae biomass for the production of triacylglycerides is a potentially valuable enabling technology for a waste water treatment-based integrated biorefinery. Here, HTC was used to treat Phaeodactylum tricornutum lipid-rich biomass producing a solid hydrochar from the surface of which adsorbed lipids were removed by hexane extraction following filtration ...

Cytotoxic properties of plant extracts and drugs being developed for cancer treatment are usually evaluated by a variety of in vivo and in vitro tests carried out in animal or plant based models. In the present study we have evaluated the possibility of using the germinating mung beans (Vigna radiata), for rapid and inexpensive screening of drugs exhibiting cytotoxic properties. Mung beans were...
