in vitro rooting of pyrus glabra boiss. microshoots
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...
متن کاملGenetic Diversity of pear (Pyrus spp) Germplasm Assessed by Simple Sequence Repeat (SSR) and Morphological Traits
This study was conducted to identify and recognize relations and diversity among accessions of the Iranianpears (Pyrus spp). A total of 34 pear accessions, derived presumably from at least six species, were subjected to simple sequence repeat (SSR) analysis. The Japanese and the Chinese pear samples were; “Housui” and “Yali” cultivars, example of Pyrus pyrifolia and P. bretschneideri, respectiv...
متن کاملIn vitro shoot proliferation and in vitro and ex vitro root formation of Pyrus elaeagrifolia Pallas
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...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Methods of Conservation of the Plant Germplasm. in Vitro Techniques
In the last decade there has been an alarming increase in the number of disappearing species from the spontaneous flora due to the pressures put upon the environment (land clearing, drainage, pollution of the soil etc.) affecting their vitality, determining their number to fall under their biological possibilities of regeneration. In the present there are 60.000 vascular species on the verge of...
