One hundred-thirty soil isolates of A. flavus were collected from commercial pistachio orchards in two main production regions including Rafsanjan (Kerman Province, south-eastern of Iran) and Damghan (Semnan Province, central north of Iran) and assayed for vegetative compatibility groups (VCGs). The sixteen and twenty VCGs were identified for 41 and 37 nit-mutant producing isolates of A. flavus...

Background: The Egyption fruit bat, Rousettus aegyptiacus, is considered a harmful pest that attacks agricultural crops, especially ripe fruits, causing economic losses. It widespread in African sahara desert, Egypt, Pakistan and Northern India. This causes damage to many vegetables fruits. measuring of percentage will aid the protection these crops from bats attacking. Methods: losses caused b...

demographic analyses of dubas bug, ommatissus lybicus de bergevin, (hemiptera: tropiduchidae), reared on five date palm varieties (zahdi, mazafati, piarom, khasi, and shahani) were constructed under laboratory conditions at 27±1ºc, 70±5% rh, and a 14:10 hours (l: d) photoperiod. data were analyzed based on the age-stage, two-sex life table theory to take the variable developmental rate among in...

The objective of the study was to analyze chemical structure of date palm (Phoenix dactylifera L.) by employing ultimate, proximate and thermo-gravimetric techniques. Samples from different anatomical parts of date palm, namely trunk, frond base, frond midrib, leaflets, coir, fruit stem, date stone, and fruit empty bunches were considered for the experiments. Based on the findings in this work ...

BACKGROUND The Arc of Fire across southern Amazonia seasonally attracts worldwide attention as forests are cut and burned for agricultural expansion. These forests contain numerous wild relatives of native South American crops, such as peach palm. METHODOLOGY/PRINCIPAL FINDINGS Our prospecting expeditions examined critical areas for wild peach palm in the Arc of Fire in Mato Grosso, Pará, Mar...

Microsatellite markers containing simple sequence repeats (SSRs) are a valuable tool for genetic analysis. Our objective was to identify microsatellite markers that could be used to differentiate between male and female date palm (Phoenix dactylifera). The date palm is a dioecious plant whose sex cannot be determined until it reaches a reproductive age between 5 and 10 years. An early selection...

Date palm (Phoenix dactylifera L.) is a monocot, dioecious and high longevity tropical plant greatly considered due to its high economic importance in Middle East. This investigation was carried out to detect genetic relations among 34 cultivars of Iranian date palm, both males and females, using ISSR markers. Accordingly, total DNA was extracted using CTAB method and was subjected to PCR ampli...

an efficient method for producing doubled haploid plants of date palm ( phoenix dactylifera l.) was established using in vitro colchicine treatment of anthers. to this study male inflorescences were harvested in the appropriate developmental stage. separated anthers after one day cold (4°c) pretreatment, in uninucleate stage of microspore were transferred to the modified y 3 medium containing d...

background: there is a rapidly growing trend in the consumption of herbal remedies in the developing countries. the phoenix dactylifera date palm pollen (dpp) is used in the traditional medicine for male infertility. the aim of this study was to determine the effects of orally administered dpp on the reproductive system of adult male rats.   methods: fifty sprague-dawley rats were maintained ac...
