Extended abstract Introduction:Echinacea purpurea, a member of Asteraceae family, is a herbal medicine which is effective for promoting human immune system. Enviromental stresses including water defecit, which limit maternal plant growth, can also affect their seed quality and germination. Various compounds such as salicylic acid and spermin are known to be useful in the alleviation of harmful ...

Extended abstract Introduction: Drought stress is one of the major problems in sugar beet production in Iran, and is the most important limiting factor for germination and establishment of sugar beet in the early stages of growth. Seed priming with chemical, nutrient elements or pre-chilling techniques are the most effective methods to improve germination percentage and speed, leading to unifo ...

Extended abstractIntroduction: Allelopathic effects of plant on one another are one of the most important concerns in reclamation and rehabilitation of rangelands in Iran. Allelopathy refers to the deterrent effects of a plant on growth, development or emergence of another plant. One of the rangeland reclamation methods is planting suitable and compatible species. However, without considering ...

DOR: 98.1000/2383-1251.1397.5. 1.10.2.1605.41Extended abstract Introduction: Germination speed is one of the most important germination indices, used in most studies to compare the effects of different treatments on seed germination. Researchers use the reverse time up to 50% maximum germination (1/D50) to calculate the germination rate. One of the methods used for calculating the D50 is the u ...

The cultivation of sunflower (Helianthus annuus L.) has significantly increased in recent years, mainly due to thequality of its oil, which is useful for the human consumption and industrial purposes. In order to investigate the effect of different seed storage temperatures on seed quality of two sunflower cultivars (Euorfluor and Rcord), seeds were exposed to three storage temperatures (5, 20 ...
