This study was carried out in order to determine the effects of boron and cold stress on pollen germination of almond hybrids in vitro culture, two different media including the absence and presence of boron (0 mg/l, and 100 mg/l) in 10% sucrose and 1% agar medium at 24°C in dark conditions. The results showed that different treatments had a significant effect on the germination percentage. The...

deterioration of seed is one of the most important limiting or even hindering factors in its germination. an evaluation and understanding of the factors responsible for/ and enhancing seed deterioration is of paramount importance. the main aim of this study was to determine the effects of seed deterioration on its germination and as well on the activities of antioxidant enzymes in canola culitv...

Germination and seedling growth of major cereals treated with Moringa oleifera leaf extracts was investigate at University of Zambia. Aqueous extract of Moringa oleifera at the ratio of 1:10 (w/v) were sprayed on seed of maize (Zea mays. L.), rice (Oryzae sativa.L.), sorghum (Sorghum bicolor. L.) and wheat (Triticum Aestivum. L.) in a growth room at 25C for 14 days. The data were subjected to a...

Rumex confertus is a biennial species native to Eastern Europe and Asia, where it thrives on meadow-steppes and glades in forest-steppe. This species has increased its range rapidly within central Europe, yet its biology is not well understood, which has led to poorly timed management. Effects of temperature, light, sodium chloride (NaCl), hydrogen ion concentration (pH), potassium nitrate (KNO...

Plant-frugivore mutualism serves an important function in multiple ecological processes. Although previous studies have highlighted the effect of frugivore gut passage on fresh seed germinability, no study has investigated the effect on seed storage after frugivore gut passage. We used the endangered plant, Euryodendron excelsum, to determine the combined effects of frugivore gut passage and st...

Germination of nine important medicinal plant species from the high altitudes of southern Africa was investigated in relation to different environmental parameters. The seeds were subjected to different constant and alternating temperatures, temperature shifts, light and dark conditions, and cold stratification periods. Temperature regimes of 17–23°C appear most suitable for optimal germination...

salvia genus has 58 annual and perennial herbaceous species in iran that 17 species are endemic and salvia sahendica boiss & buhse is one of them. in order to investigate the effects of drought stress caused by peg 6000 and salinity stress induced by nacl on germination factors of salvia sahendica, two experiments were carried out based on a completely randomized design with 3 replications. in ...
