Germination was reduced by water stress (-4 bars) or CO2-free air, but ethylene reversed the reduction even when administered after several days incubation. This suggested that environmental and hormonal factors affected redroot pigweed seeds at two distinct stages in the sequence of germination ...
Anthropogenic nutrient enrichment and shifts in herbivory can lead to dramatic changes in the composition and diversity of aboveground plant communities. In turn, this can alter seed banks in the soil, which are cryptic reservoirs of plant diversity. Here, we use data from seven Nutrient Network g...

established to be at least 10,000 years old germinated within 48 hours when returned to favourable conditions. The problem of differential seed viability has been approached experimentally by various workers, one of whom buried 20 species of common Michigan weed seeds, mixed withsand, in inverted ...
Field appraisal of seed priming to improve the growth, yield, and quality of direct seeded rice. Poor crop stand and high weed infestation are the major constraints of direct seeded rice. Seed priming has the potential to improve the seedling emergence... REHMAN,Hafeez,Ur,... - 《Turkish Jo...
Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds into contact with stator bars at angularly spaced positions around the axis of the rotor. U...
Milkweed is now being grown commercially mainly for the production of floss used as hypoallergenic fillers in pillows and comforters. More recently, the use of milkweed seed oil in soaps and personal care products is being explored. The oil used in this effort was obtained by screw pressing ...

Since 1970s, some researches have been conducted to probe the suitable rice varieties, crop management and weed control in double direct-seeded rice system in central China4,5. However, poor crop establishment of direct-seeded early rice due to chilling stress is the main obstacle to wide sprea...
Some root-parasitic plants belonging to the Orobanche, Phelipanche or Striga genus represent one of the most destructive and intractable weed problems to agricultural production in both developed and developing countries. Compared with most of the other weeds, parasitic weeds are difficult to control ...
