Seasonal dynamics of seed dormancy and germination in the weed .

Background: Understanding the reproductive biology of weeds is crucial for managing them effectively. (Poaceae) is a widely distributed weed species that poses significant challenges to agricultural productivity. Nevertheless, it remains unclear how the soil seed bank of responds to environmental shifts, and whether a dormancy cycle is present in this species.

Geographic distribution and impacts of climate change on the suitable habitats of Rhamnus utilis Decne in China.

Background: Rhamnus utilis Decne (Rhamnaceae) is an ecologically and economically important tree species. The growing market demands and recent anthropogenic impacts to R. utilis forests has negatively impacted its populations severely.

The components of rice and watermelon root exudates and their effects on pathogenic fungus and watermelon defense.

Watermelon (Citrullus lanatus) is susceptible to wilt disease caused by the fungus Fusarium oxysporum f. sp niveum (FON). Intercropping management of watermelon/aerobic rice (Oryza sativa) alleviates watermelon wilt disease, because some unidentified component(s) in rice root exudates suppress FON sporulation and spore germination.
