Allelopathic Potential of Achillea biebersteinii Afan. (Asteraceae)
The effects of different concentrations (0, 25, 50, 75 and 100%) of aqueous leachate of Achillea biebersteinii on germination characteristics, seedling growth, photosynthetic pigments and protein contents of pepper (Capsicum annuum L.) were investigated through conducting laboratory and greenhouse experiments. Leachate of A. biebersteinii affected negatively germination percentage, germination ...
متن کاملGenotypic variation in P efficiency of selected Iranian cereals in greenhouse experiment
A factorial completely randomized block design experiment with three replications was carried out in greenhouse to evaluate cereal genotypic variation in phosphorus (P) acquisition and utilization efficiency in a calcareous soil with low available P (4.6 mg P kg-1 soil) and high total P (1260 mg P kg-1 soil). Treatments consisted of eight bread wheat (Triticum aestivum L.), three durum wheat (T...
متن کاملPotential selection for female choice in Viola tricolor
That sexual selection can be an active force in plant evolution is still under debate. When the number of pollen grains deposited onto a stigma exceeds the number of available ovules, competition among pollen grains for fertilizations will result in selection on traits that increase siring ability (e.g. pollen tube growth rate). The pistil can be regarded as an arena for pollen competition, whe...

متن کاملLily Cultivars Have Allelopathic Potential in Controlling Orobanche aegyptiaca Persoon
As a devastating holoparasitic weed, Orobanche aegyptiaca Persoon. (Egyptian broomrape) causes serious damage to agricultural production and threatens economic development, which has raised widespread concern. The present study was conducted to determine whether lilies have the potential to be used as 'trap crops' for controlling O. aegyptiaca Persoon. In the experiments, the ability of three p...
