Drought is one of the most important natural phenomenon which affects on plant growth. Alfalfa (Medicago sativa L.) is an essential fodder product which has extensive and depth roots system, this advantage enables the plant to tolerate long term drought without any damage to its regrowth process. In order to measure germination percentage and rate, root and shoot growth of 6 alfalfa cultivars (...

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...

Early germination of white oaks is widely viewed as an evolutionary strategy to escape rodent predation; yet, the mechanism by which this is accomplished is poorly understood. We report that chestnut oak Quercus montana (CO) and white oak Q. alba (WO) (from North America), and oriental cork oak Q. variabilis (OO) and Mongolian oak Q. mongolica (MO) (from Asia) can escape predation and successfu...

The effect of leachates of different phenological stages of Cassia occidentalis L. on Parthenium hysterophorus L. was studied. Seed germination, radicle length, plumule length and fresh and dry weight of Parthenium were recorded. Pigments and protein contents were also measured to evaluate relation between biochemical and biophysical parameters of Parthenium under stress. The leaf leachate of C...

Grass pea (Lathyrus sativus L.) is relatively tolerant to several abiotic stresses such as salinity. Twenty-five grass genotypes provided by the Dryland Agricultural Research Institute, Maragheh, Iran, were exposed four salinity levels (0, 40, 80, 120 mM). Based on primary screen, 8 and 17 sensitive selected. Principal components analysis for showed that first explained approximately 71-80% of ...
