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 ...

A prerequisite for most plant transformation systems is an efficient and reliable method to regenerate phenotypically normal plants. The present studies were undertaken with a view to the effects of Benzyl amino purine (BAP) and Indol butyric acid (IBA) hormones and genotypes on in vitro germination of immature embryos in walnut (Juglans regia L.). The immature embryos of walnut were excised fr...

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...

this study was conducted with the main prupose of investigation the effects of culture medium and the concentration of growth regulators on proliferation rate, rooting and the acclimatization of gisela 6 rootstock at khorasan razavi agriculture and natural resource research center during 2011-2012. in this experiment, the proliferation and rooting were performed in six kinds of culture medium (...

The Dvoretzky–Kiefer–Wolfowitz (DKW) inequality says that if Fn is an empirical distribution function for variables i.i.d. with a distribution function F , and Kn is the Kolmogorov statistic √ n supx |(Fn − F )(x)|, then there is a finite constant C such that for any M > 0, Pr(Kn > M) ≤ C exp(−2M2). Massart proved that one can take C = 2 (DKWM inequality) which is sharp for F continuous. We con...

Pruacan is a rare medicinal plant endemic to the Dieng Plateau of Central Java, Indonesia which has properties as an aphrodisiac. Increasing genetic variability ofthis in order support breeding programs and increase productivity active ingredients this important. This study aimed evaluate effect chemical mutagen EMS on growth development vitro culture pruacan lethal dose determination. Embryoge...

Background and objectives: Hawthorn as an ethno-pharmaceutical plant has been consumed for 2,500 years. Flowers, leaves and fruits of hawthorn are rich in antioxidant and polyphenols and are popular in the treatment of congestive heart failure. Methods: In the present study, by using various media and plant hormones the regeneration and callogenesis capacity of...
