Plants have the capability to produce an extensive variety of chemical compounds that in turn exert important biological functions and modify different pathological conditions in both human and animals. In this way medicinal plants mediate their effects through Chemical compounds and these processes are identical to those already well understood for the chemical compounds in conventional drugs....
Streptomycin is used in plant agriculture for bacterial disease control, particularly against fire blight in pome fruit orchards. Concerns that this may increase environmental antibiotic resistance have led to bans or restrictions on use. Experience with antibiotic use in animal feeds raises the possible influence of formulation-delivered resistance genes. We demonstrate that agricultural strep...
Almond [Prunus dulcis (Mill.) D.A. Webb] is one of the most important cultivated fruit trees in Iran. Late frost in spring is a key limiting factor for almond productivity given that almond trees flower early in the spring in comparison with other temperate fruit trees. To decrease frost injury in “Mamaei” cultivar, this study was carried out in factorial randomized complete block design (CRBD)...
this study was carried out on olive trees cv. amygdalifolia, to investigate the effect of spraying potassium nitrate, kno3, and zinc sulfate, znso4, on the fruit weight, dimension and volume. the plants were sprayed with 0, 0.5, 1.0 and 1.5% kno3 and 0, 0.25, 0.50 and 0.75% znso4 and their combinations in august about halfway through the fruit growth period. the highest fruit weight was observe...
Spatial isolation caused by forest fragmentation and temporal isolation caused by asynchronous flowering of plants have been proposed as important factors that affect the reproduction ofplant populations. In a 4-year study, we determined the effects of forest fragmentation and spatial isolation on flowering phenology and reproductive success of the tropical tree Ceiba aesculifolia ([Kunth] Brit...
To evaluate the effects of chemical and hand fruit thinning on pistachio flower bud retention, experiments were conducted during 1382 and 1383. In the first year, ethephon treatments at the concentrations of 100 and 200 mg L-1, urea at 2.5% and 5%, naphthaleneacetic acid (NAA) 125 and 250 mg L-1 and naphthaleneacetamide (NAD) 250 and 500 mg L-1 were sprayed on two branches of nine uniform trees...

The development of flower buds and a sufficient fruit set are basic requirements for fruit growers to generate a marketable crop. However, fruit trees remain in a juvenile (nonflowering) phase for years, and after a transition period of getting reproductively competent they enter the adult phase of tree life. The reproductive phase is associated with the ability to alternate between the product...
Ecological complexity has been proposed to play a crucial role in primate brain-size evolution. However, detailed quantification of ecological complexity is still limited. Here we assess the spatio-temporal distribution of tropical fruits and young leaves, two primary chimpanzee (Pan troglodytes) foods, focusing on the predictability of their availability in individual trees. Using up to 20 yea...
