otostegia persica (burm.) boiss. is the medicinal plant of lamiaceae family that has long been used traditionally in treatment of severe diarrhea, common cold, flatulence, headache, sore, fever, skin allergies, and blood fat and sugar. this research was conducted in 2013 for one year to identify some ecological characteristics and potential allelopathicof o. persica in hormozgan province. the c...

Abstract The obstacles that farmers face by using the True Shallot Seed (TSS) due to germination ability. In a laboratory level, application of bio-stimulants was tested enhance TSS germination. Two types namely Bio A and B with 16 treatment were TSS. Hypocotyl length, speed seed germination, percentage, seedling growth rate, number dead seeds abnormal seeds, fungi-infected bacteria-infected al...

Micropropagation is an alternative for the genetic conservation and propagation of endemic species from “Campo Rupestre Ferruginoso”, such as orchid Cattleya crispata. The aim present study to assess influence activated charcoal on in vitro germination, multiplication elongation phases C. Seeds extracted mature capsules were used inoculation culture medium that was adopted effect supplementatio...

Abstract: Seed conditioning improves germination uniformity, speed, and dormancy release. This work aimed the study physiological of Urochloa humidicola cv. Llanero, using two lots dormant seeds conditioned by imbibition with water, commercial bioregulator (auxin, gibberellin - 0.144 mM cytokinin), (0.144 1.44 mM) or 5% ethanol. Germination, dormancy, SOD activity, MDA H2O2 content were evaluat...

orchids are one of the most popular plants in the world and among them phalaenopsis genus have the most sales in a global market. because of its hard propagation, micropropagation technique has been employed recently. in this study, we tried to find out useful protocol for commercial production through in vitro culture. at first, for seed capsules production, flowers were pollinated with hand i...
