The effects of Drought and salinity stress on the growth and chemical compositions pennyroyal(Mentha pulegium L.) plant were investigated. This experiment was carried out in a factorial-randomized design with four replications in controlled conditions and plantlets were subject to four soil moisture regimes (40, 60, 80 and 100 of field capacity (FC)) and five salt treatments with 0, 25...
Weedy rice is a species of Oryza, and wild relative cultivated rice. The weed possesses unique hardiness that allows them to thrive in dynamic stressful environments. These characteristics suggest weedy stored source novel genes for competitive traits. One such trait allelopathy, where releases secondary metabolites suppress the growth development neighboring species. Weed competition limiting ...
Several studies have focused on fine roots characteristics because they provide a major pathway for nutrient cycling and energy flow in forest ecosystems. However, few studies have evaluated changes in fine root characteristics according to their diameter. Pinus massoniana forests are the main vegetative component in the Three Gorges Reservoir area and play an important role in providing forest...
Damage from a dormant-season windstorm in a 3-year-old Populus research trial differed among four clones and three spacings and between monoclonal and polyclonal plots. Clonal differences in susceptibility to toppling (or leaning) were associated with both above-and below-ground characteristics. Susceptible clones had less taper in the lower stem and more weight in branches on the upper stem. T...
