Attempts were made during the 1990 growing season to induce somatic embryos from non-zygotic tissues of five economically important walnut cultivars. The following explants were employed: fertilized and unfertilized ovules; immature and mature catkins; abnormal "spike" flowers; and in vitro-grown leaves and roots. Modifications of the standard induction media were also examined. These included ...

The effect of nephronic mass reduction of kidney transplants has not been analyzed specifically in a large cohort. Transplant injuries in cadaver kidney graft may have led to an underestimation of the magnitude of this factor. The aim of this study was to analyze the consequences of kidney mass reduction on transplantation outcome. The weights of 1142 kidney grafts were collected prospectively ...

this research was conducted to study the factors affecting establishment, growth and shoot proliferation of persian walnut, genotype z60. explant establishment was studied through a factorial experiment based on a completely randomized design with two factors including culture media (dkw and wpm) and ba concentration (0 (control), 0.5 and 1.0 µm). single-node explants were prepared from the you...

aucuparia is an important slow growth forest tree with medicinal, industrial and ornamental uses which is applied for reforestation in high altitude of mountain lands. this species has been endangered at northern forests of iran; therefore micropropagation of adult trees by bud culture may help to reforestation. the best sterilizing treatment was the buds washing with hgcl2% 0.1 solution for 7 ...

Micrografting can be used to produce healthy seedlings, assess scion-rootstock compatibility and promote precocity. The first objective of this project was to study the impacts of in vitro micropropagation of four major Iranian pistachio cultivars, namely ‘Ahmad Aghaei’, ‘Akbari’, ‘Badami Sefid’ and ‘Kalle Ghochi’ in two different medium Murashige and Skoog (MS) and Driver and Kuniyuki...

Routine production of large numbers of transgenic plants is required to fully exploit advances in cassava biotechnology and support development of improved germplasm for deployment to farmers. This article describes an improved, high-efficiency transformation protocol for recalcitrant cassava cultivar TME14 preferred in Africa. Factors that favor production of friable embryogenic calli (FEC) we...
