In vitro asymbiotic germination of immature seed and formation of protocorm by Cephalanthera falcata (Orchidaceae).
BACKGROUND AND AIMS Many Orchidaceous species are threatened globally by development and over-collection from their natural habitats for horticultural purposes. Artificial propagation from seeds is difficult in most terrestrial orchids native to temperate regions. Seed production is another limiting factor in the artificial propagation for these species because of the lessened probability of po...
متن کاملImportance of woody debris in seed germination of Tipularia discolor (Orchidaceae).
Concerns about declining populations of terrestrial orchids make it important to identify the environmental factors crucial to seedling recruitment. This study shows that seedlings of Tipularia discolor (cranefly orchid) primarily occur on decomposing wood. Extensive searches of decomposing logs and stumps in mature and successional forests revealed seedlings at 24 sites, of which 15 could be i...
متن کاملEffects of culture medium and supplementation on seed germination, protocorm formation and regeneration of some Phalaenopsis hybrids
An efficient protocol is suggested for in vitro culture of five Phalaenopsis hybrids obtained by hand-cross-pollination of three commercial hybrids Calgary, Ankara, and Kendall. Four nutrient media- namely half-strength Murashige and Skoog, Knudson, Phytamax containing activated charcoal, and Mitra– once supplemented (with coconut water, peptone, or both), and once without any supplement were c...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
