Seed dormancy, by controlling the timing of germination, can strongly affect plant survival. The kind of seed dormancy, therefore, can influence both population and species-level processes such as colonization, adaptation, speciation, and extinction. We used a dataset comprising over 14,000 taxa in 318 families across the seed plants to test hypotheses on the evolution of different kinds of see...

ABSTRACT Considering the cashew tree’s relevance and limitations imposed by salinity stress in semi-arid regions, use of alternatives capable mitigating harmful effects due to is great importance production sector. The grafted plants, especially with rootstock made tolerant materials, influences accumulation toxic ions leaves seedlings. Thus, objective this work was evaluate morphophysiological...

In order to study the effects of terminal heat stress and nitrogen on morphophysiological characteristics, ANUE (Agronomical Nitrogen Use Efficiency) and yield of canola, an experiment was conducted at research farm of Ramin Agricultural Sciences and Natural Resources university. The experiment was arranged in split plots based on randomized complete block design with four replications. Main pl...

abstract in order to study the effect of different water potential on anethum graveolens two experiments were conducted for germination and vegetative stages. this study was carried out as a factorial experiment based on completely randomized design with three replications. in the first experiment, response of dill seeds germination to levels of drought stress including to drought potentials ze...

recently, application of sa has increased to improve plants resistance to stresses such as drought. hence, to investigate sa effects on morphophysiological characteristics of fennel(foeniculum vulgare mill.) under drought stress, a split plot experiment based on latin square design with three replications was carried out at research farm of shahid bahonar university of kerman in 2012. three lev...
