, indicating ‘endogenous dormancy’. The best germination occurred in seeds soaked in 400 ppm GA3 for 24 hours and given moist chilling at 5°C for one week. In this treatment, total germination reached 92%. Dormant seeds showed low enzyme activity, while enzyme...

Echinacea purpurea (Asteraceae) is an important medicinal plant known as a disinfectant.

Its germination percentage and germination rate is generally low due to

dormancy. Dormancy and germination requirements were investigated...

Previous studies have shown that seeds of some rangeland plant species are dormant at

maturity. Seed dormancy is a characteristic that can both help maximize the probability of seedling

establishment and spread the risk of recruitment...

Domestication of medicinal plants is an aim to both improve their availability and to protect their natural habitants due to over harvesting. However, the presence of dormancy in the species is a problem for assessing seed quality for cultivation...

germination testing in the presence of dormancy in non-crop species presents problems in assesing seed quality for sowing. Seeds of 36 important medicinal plant species produced in North Iran (Mashhad) which had been stored in warehouses since October 2005...

Demand for medicinal plants puts their natural habitats in danger due to over harvesting; hence

their domestication is needed. However, seed dormancy can be a problem in their cultivation.

Therefore, seeds of one hundred species from...

Colchicum kotschyi Boiss grows wildly in Iran. Propagation of this perennial geophyte plant takes a long time either by corm or seed. Seeds usually have a deep dormancy and take more than a year to germinate. Therefore in order to find out...

In order to evaluate different methods of seed dormancy breaking for Chinese lantern (Physalis alkekengi L.), two experiments were conducted at laboratory and greenhouse conditions. The laboratory treatments were 22 different physical and chemical...
