Allelopathic effects of aqueous extract of rhizomes of  Cynodon dactylon L. were studied on seed germination and seedling growth of three legume crops (Phaseolus vulgaris L., Pisum sativum L., and Vicia faba L.), three Labiatae species (Thymus vulgaris L., Melissa officinalis L., and Mentha spicata L.), and two species of Poaceae (Avena fatua L., Sorghum halepense L.). Seed germination of all L...

interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. to protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. as main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. ecologically, functional parameters such as stab...

The pollen calendar of Agra was recorded with special reference to allergenic significance. Pollen grains of 35 species belonging to 23 angiosperm families have been identified out of a total catch of 24,220/m3 of air annually. High occurrence of pollen grains in air belonged to Asteraceae (5222/m3) and Parthenium hysterophorus contributed the maximum (17.91%) of the total airspora. Higher coun...
