Cajanus cajan is an important pulse crop of India and Parthenium hysterophorus is an invasive weed of agroecosystem. The main aim of this study was to evaluate the effect of leaf extract of Parthenium hysterophorus of different concentrations on the rate of seed germination and seedling growth of Cajanus cajan, and to know the allelopathic effect is the main cause of success of P.hysterophorus ...
Understanding the key aspects of plant regeneration from seeds is crucial in assessing species assembly to their habitats. However, the regenerative traits of seed dormancy and germination are underrepresented in this context. In the alpine zone, the large species and microhabitat diversity provide an ideal context to assess habitat-related regenerative strategies. To this end, seeds of 53 spec...
During seed maturation and germination, major changes in physiological status, gene expression, and metabolic events take place. Using chlorophyll sorting, osmopriming, and different drying regimes, Brassica oleracea seed lots of different maturity, stress tolerance, and germination behavior were created. Through careful physiological analysis of these seed lots combined with gene expression an...
Abstract Dorema ammoniacum is a medicinal plant, with plenty of chemical constituents, which has been used extensively in curing diseases. To study the salt tolerance of Dorema ammoniacum, its seedlings were put under different salinity treatments under hydroponic conditions. Dorema ammoniacum seeds were transferred to cold (4-5 °C) pretreatment for germination for 27 days. The germinated seed...
To assess the effects of livestock grazing on soil compaction (density changes), the trampling action of livestock was simulated. The research field was located to the south west of Nazarabad in Savojbolagh district, south west of Tehran Province. Samples were annually collected based on a completely randomized design. From the triple regions (reference, key and critical) 36 cylindrical cores w...
Extended abstract Introduction: Using of plant growth regulators is one of the methods can improve plant growth against environmental stresses such as salinity. Salicylic acid plays an important role in physiological processes regulation, including germination. Today, using of growth promoting bacteria has been increased and it causes to raise the seed vigor, uniformity, germination percentage...
