The successful production of soybean seeds is dependent on the sowing date, because every outside optimal time contributes to losses yield. aim study was identify response date chosen cultivars by evaluation length vegetation period, yield level, its parameters and seed chemical composition. A field experiment conducted in years 2016–2019 at Agricultural Experimental Station Grabów (Masovian Vo...

Seed production in the endemic New Zealand mistletoe Peraxilla tetrapetala (Loranthaceae) has been shown to be consistently pollen limited, but to date there has been no test of whether the species is also seed limited. If it is not seed limited, then pollen limitation may have no effect on population size.We tested for seed limitation by sowing seeds onto host trees at high and low densities a...

Questions: Is seedling emergence limited by the set of viable seeds, by incompatibility between the phenology of seed shedding and timing of mowing, or by dry weather in germination periods? Does seedling mortality fluctuate with season and weather? Location: Negrentino, southern Alps, Switzerland. Methods: Fecundity estimates of the dominant grass Bromus erectus; highly frequent counts of spon...

Cotton is the most important textile crop as a result of its long cellulose-enriched mature fibers. These single-celled hairs initiate at anthesis from the ovule epidermis. To date, genes proven to be critical for fiber development have not been identified. Here, we examined the role of the sucrose synthase gene (Sus) in cotton fiber and seed by transforming cotton with Sus suppression construc...
