Calotropis proceran (Asclepidaceae) is an evergreen plant and widely distributed in Hormozgan province. This plant has the allelopathic properties including germination inhibition, plumule and radicle growth reduction. In this study the effect of different concentrations (0, 5, 10, 20, 40 and 60%) of dry leaf water extraction of this plant on the germination of cucumber (Cucumis sativus), tomat...

Seed priming is a technique which is potentially able to promote rapid and more uniform seed germination and plant growth as well. In this regards, the presowing effects of seed priming treatments were investigated on some physiological viz. seed germination, germination rate, radicle elongation, shoot elongation, radicle dry weight, shoot dry weight and vigor index. Seeds were subjected to two...

The genus Thymus is perennial medicinal plants belong to the Lamiaceae familythat is used for different propose in pharmaceutical industry. Environmental stresses,particularly salinity, are considered as the major factor reducing plant growth. The purpose ofthis study was to investigate the effects of salt stress on germination characteristics andseedling morphology in two medicinal species of ...

Acyl-CoA dehydrogenase activity has been measured in homogenates of post-imbibition to 14-day-old hydroponically grown pea seeds at daily intervals, using C(4), C(12) and C(16) acyl-CoA substrates. The activity peaks of the different chain-length acyl-CoA dehydrogenases did not transpose at all points and the ratios of the chain-length activities were not constant. It therefore has to be conclu...

In order to evaluate effect of salinity on germination and early seedling growth of lentils a laboratory experiment was conducted at Biotech Research Center of the University of Zabol, in 2011. The experimental design was a completely randomized with five NaCl solution, together with seven replicates. The seeds were germinated in Petri dishes, on with 10 mL of either double-distilled water (con...

BOA (2-benzoxazolinone) is a potent phytotoxin present in several graminaceous crops such as rye, maize and wheat. Due to its wide range of phytotoxicity, it is considered as a potential pesticide. A study was conducted to explore the impact of BOA on the radicle and plumule elongation of mung bean (Phaseolus aureus) and associated changes in the macromolecular content - proteins and carbohydra...
