effect of salinity on seed germination and seedling growth of native populations of tall fescue in iran
introduction: worldwide, more than one-third of irrigated land is salinized, and in many regions, fresh water shortage has resulted in restrictions on the use of potable water for landscape irrigation. on the other hand, rapidly expanding population growth is occurring in many arid regions, where soil and water salinity are problems and there are increased demands on limited fresh water resourc...
متن کاملEffect of Cadmium Levels on Seed Germination and Seedling Growth of Spinach (Spinacia oleracea) Under Salinity Stress
Cadmium is highly toxic heavy metal. Soil factors such as pH, caution exchange capacity, CaCO3 content and salinity have a significant influence on Cd uptake by plants. Moreover, soil salinity has a great impact on crop yield in Iran. Therefore, the effect of four salt levels (0, 45, 90, 180 mM) of NaCl solutions and four concentrations (0, 15, 30, 60 ppm) of Cadmium sulfate solutions on seed g...
متن کاملStudies on seed germination and growth in weed species of rice field under salinity stress.
An investigation was made to see the salt tolerance of 10 weed species of rice. Properly dried and treated seeds of weed species were placed on 9 cm diameter petridishes lined with Whatman No. 1 filter paper under 6 salinity regimes, viz. 0 (control), 4, 8, 16, 24 and 32 dS m(-1). The petri dishes were then kept in germinator at 25 +/- 1.0 degrees C and 12 hr light. The number of germinated see...
متن کاملThe Arabidopsis Phytocystatin AtCYS5 Enhances Seed Germination and Seedling Growth under Heat Stress Conditions
Phytocystatins (PhyCYSs) are plant-specific proteinaceous inhibitors that are implicated in protein turnover and stress responses. Here, we characterized a PhyCYS from Arabidopsis thaliana, which was designated AtCYS5. RT-qPCR analysis showed that the expression of AtCYS5 in germinating seeds was induced by heat stress (HS) and exogenous abscisic acid (ABA) treatment. Analysis of the expression...
متن کاملEffect of Silver Nanoparticles on Seed Germination and Seedling Growth in Thymus vulgaris L. and Thymus daenensis Celak under Salinity Stress
Germination represents a fundamental stage of plant life highly responsive to change of environmental conditions. Low germination percent and seedling establishment are basic problems in saline regions. One of the sensitive stages of plants to salinity is the germination stage. This study was conducted using a factorial experiment with three factors such as species with two levels (Thymus vulga...
