Culture medium and light are important factors that affect the process of in vitro propagation plants. Particularly for orchids, diverse culture media have been evaluated micropropagation many species hybrids. More recently, light-emitting diodes (LEDs) become widely used agriculture, including commercial operations, resulting increased production reduced costs compared to traditional fluoresce...

Methodological recommendations for lighting modes growing rootstocks and varieties of domestic plum at the stages micro propagation, in vitro rooting ex adaptation determine usage lamps with different light spectra, allowing to obtain more higher results clonal including: height regenerated plants number leaves, propagation ratio; development root system; growth physiological state stage adapta...

fars province is one of the natural habitats of pyrus species in iran. harvesting of fruits, deforestation, expansion of agriculture and overgrazing in recent years has threatened the wild pear open forests and imposed detrimental effects on their natural regeneration, therefore, investigation on propagation of wild pear species for afforestation is needed. this research was carried out to deve...

Shoot-tip cultures of Pyrus elaeagrifolia Pallas, an important gene source for drought and chlorosis resistance in pear rootstock breeding, were established from a wild mature tree originated from seed. Murashige and Skoog basal medium supplemented with different concentrations of benzyladenine (BA) singly or in combination with auxin was used in the study. In the initial culture, the highest p...

Direct rooting and rooting via a wound tissue in Pinus sylvestris L. and Pinus contorta Dougl. ex Loud. hypocotyl cuttings in vitro were studied. Direct rooting usually occurred within three weeks after cutting. Three to four weeks after cutting, roots developed either directly on the hypocotyl or via a wound tissue. Later than one month after cutting, rooting took place predominantly via a wou...

Effects of various culture media and growth regulators on micropropagation of cherry rootstock, M × M60 were investigated in the present study. Stem cuttings of the current season growth were taken from mature stockplants and cultured on the establishment medium after disinfection. After four weeks, elongated shoots were cut and subcultured on the proliferation media including MS, DKW, QL and M...
