For human food security, the preservation of 7.4 million ex-situ germplasm is a global priority. However, ex-situ-conserved seeds are subject to aging, which reduces their viability and ultimately results in the loss of valuable genetic material over long periods. Recent progress in seed biology and genomics has revealed new opportunities to improve the long-term storage of ex-situ seed germpla...

the germination power of orchids (orchidaceae family) seems to betoo weak due lack of albumen. the study carried out with various treatments including pollination time and ga3 for breaking dormancy and increasing seed germination of orchids. the effect of pollination time (8 periods from january to august) and gibberellic acid (0, 500, 1000 and 1500 mg l-1) were studied on germination of phalae...

present study examines whether there is any beneficial effect of magnetized water application on seedling emergence of maize seeds. water from various sources like tap water, saline water (1,500 ppm), canal water, and sewerage water was treated magnetically by passing it through 235 mt magnetic fields at 3 lpm flow rate. seeds were soaked in water for 24 hours and planted in sand culture. numbe...

wych elm (ulmus glabra hudson) is one of the forest species in hyrcanian forests of iran and considered as threatened species due to its narrow ecological range, over-exploitation, as well as dutch elm disease. in order to evaluate the possibility of cryopreservation of ulmus glabra seeds for long-term preservation, seeds were collected from natural habitats and three pre-treatment methods incl...
