seeds of most herbs such as medicinal plant alyssum bracteatum are known to have a dormancy period in a natural condition. therefore, the identification of factors affecting seed dormancy and germination in order to create optimum conditions for large-scale cultivation of medicinal plants is necessary. the survey was conducted at the research laboratory of biology, university of lorestan in aut...

Salinity stress is one of the main factors that limit seed germination and plant growth. Therefore, magnetic water was used because it had a positive effect on germination. This study conducted to investigate (MT1, MT2, MT3, MT4, MT5) treatment passing through magnets 1, 2, 3, 5, 8 times respectively, non-magnetic (NMT) cucumber seeds (Cucumis sativus L.) under salinity (NaCl) (S1 = 0.38 dSm-1,...

Deterioration of seeds is an important problem leading to low germination and uneven crop establishment causing poor growth productivity. Soil salinity another factor limiting cultivation. Spermidine (Spd) a compound widely reported for diminishing adverse effects salt stress in plants. In this study, the Spd priming on normal deteriorated rice were investigated under during young seedling stag...

Antifungal activities of twenty four plant extracts and secondary metabolites of five Trichoderma strains were tested against conidial germination and germ tube growth of Colletotrichum capsici. Hundred percent inhibition of conidial germination and shortest germ tube formation of Colletotrichum capsici were recorded in Azadiracta indica (leaf), Ocimum sanctum (leaf) and Curcuma longa (rhizome)...

Seed germination generally presents a peak in the next growing season after a fire. Among other factors associated with fire are the increase of soil nitrogen and changes in the pH of the soil. In this study, we addressed the question, whether or not the germination response of eight species is linked with the increase in pH and nitrogenous compounds in the germination media? We assessed the se...

The present investigation attempted to assess the impact of seed pre-treatments on the germination of Crotalaria persica (Burm. f.) Merr and Tephrosia apollinea (L) Pers. Equally important was our investigation to quantitatively compare different germination parameters used for seed germination studies. The results showed that the final germination was highest for both species under chipping (C...

this study was conducted to quantify germination response of annual savory (satureja hortensis l.) to temperature and water potential. for this purpose, seeds were exposed to different temperature (12, 15, 20, 25, 30, 35, 37 and 40°c) and water potential (zero, -0.1, -0.3, -0.5 and -0.7 mpa) treatments in seed research lab., gorgan university of agricultural sciences and natural resources in 20...
