sexual behavior in most moths is limited to a precise duration period of either the day or the night. these behaviors as well as the calling behavior are specific. information on reproductive behavior is important in the chemical ecology studies. experiments were conducted to determine the developmental biology, adult time emergence and calling behaviors of three populations of carob moth, ecto...

quality and flesh colour characteristics of blood oranges following harvest is related to and dependent upon temperature and storage conditions. to investigate the effects of different temperatures (8, 15 and 22ºc) and different storage period (0, 25, 50 and 75 days) on total soluble solids, titrable acidity, ph, ascorbic acid, total phenolic contents, antioxidant capacity, anthocyanin level, a...

hybrid rice varieties are potentially higher yielding than the best inbred varieties and perform better under adverse conditions of drought and salinity. one of the major impediments for seed production of hybrid rice is incomplete panicle exsertion in the cytoplasmic male sterile lines. the unexserted spikelets which are left inside the flag leaf sheath remain unfertile. this research was focu...

introduction earth has ever been exposed to environmental hazards. the hazards are continually occurring in the world in the recent years. among them, atmospheric elements have created many human and financial losses in different regions. one of the hazards is dust events and in its severe case is dust storm. it happens more frequently in arid and semiarid regions in deserts and their surroundi...

with the aim to examine lead tolerance of populus nigra (clone 62/154) in symbiosis with arbuscular mycorrhizal fungi, a greenhouse experiment was carried out in a factorial randomized complete scheme with two factors 1) fungal inoculation in 4 levels (control, inoculation with glomus mosseae, inoculation with g. intraradices and inoculation with g. mosseae + g. intraradices) and 2) lead in 4 l...

drought is the most common environmental stresses that affects plant growth. to study the combined effects of arbuscular mycorrhizal fungi (glomus intratadices) and jasmonic acid on growth and ecophysiologycal characteristics of pistachio seedlings cv. qazvini under drought stress, a greenhouse experiment was conducted in a completely randomized design with three replications. experimental fact...

the purpose of this study was to examine the effectiveness of nanosilver colloid as a new antimicrobial agent against erwinia in tissue culture of sugar beet for the recovery of the contaminated doubled haploid plantlets. the nanosilver colloidal solution of 4000 ppm was diluted in different concentrations (0, 50, 75, 100 and 125 ppm) and was added to the solid ms medium. in a factorial experim...

a synoptic method based on stream analysis is applied to understand the governing mechanism of summer rainfall occurrence in the south of iran. based on this, the rainfall data of 152 stations of iran were analyzed for a 33-year period (1970-2002). investigating the spatial and temporal distribution of summer rainfall, a typical rainy region is recognized in the south east of iran. it is found ...

political islam is the only active religion discourse in the world claiming to have program for religion and the muslim world and to achieve this goal it must gain political power. from its existence the dialogue has triggered different experiences in islamic countries. the most important victory of the islamic revolution in iran in 1979 and egypt's muslim brotherhood movement was to seize...

phosphosulfonic acid (psa) was found to be an efficient catalyst for the one-pot three-component hantzsch condensation reaction of arylaldehydes, ethylacetoacetate and ammonium acetate to afford the corresponding 1,4-dihydropyridine and polyhydroquinoline derivatives in high yields. psa was also applied for the one-pot preparation of polyhydroquinolines via four-component reaction of arylaldehy...
