Effects of water stress on fruit fresh and dry weights were investigated in peach trees, Prunus persica (L.) Batsch., with varying crop loads: light, moderate and heavy. In well-watered controls, tree water status was independent of crop load. In trees receiving reduced irrigation, the degree of water stress increased with increasing crop load. Water stress induced fruit fresh weight reductions...

The amount of unfrozen water in dormant peach (Prunus persica [L.] Batsch, cv Redhaven) flower buds, isolated primordia, and bud axes was determined during freezing using pulse nuclear magnetic resonance methods. Differential thermal analysis studies were conducted on whole buds and isolated primordia in the presence of ice nucleation. The results showed that some of the water in isolated primo...

Helminthes infections are the most common health problems in India, in developing countries they pose a large treat to public. These infections can affect most population in endemic areas with major economic and social consequences. The miswak is a natural toothbrush made from the twigs of the Salvadora persica (Salvadoraceae). Miswak prevents tooth decay, eliminating toothaches and halt furthe...

BACKGROUND Elastomeric chains are commonly used in orthodontics. Force decay in these materials poses clinical problems. The aim of this study was to evaluate the effects of three different mouthwashes on the force decay of orthodontic chains. MATERIALS AND METHODS In this experimental study, elastomeric chains with two different configurations were divided into eight groups (two control and ...

Many studies have supported the enemies hypothesis, which suggests that natural enemies are more efficient at controlling arthropod pests in polyculture than in monoculture agro-ecosystems. However, we do not yet have evidence as to whether this hypothesis holds true in peach orchards over several geographic locations. In the two different geographic areas in eastern China (Xinchang a town in t...

BACKGROUND AND AIMS The distribution of canopy growth among different shoot types such as epicormic, long and short shoots is not well understood in the peach tree. In this experiment, the effects of crop load and early epicormic sprout removal on current and subsequent-year distribution of vegetative growth among epicormic, long and short shoots was investigated in Prunus persica. METHODS Fi...

years later Perroncito sketched the microbe. Detailed observations were not made 011 t1, disease until 1879-80, when Toussaint demonstrated that a microbe was the cause of the infectivity of the blood, and Pasteur observed that birds, when fed upon the smallest drop of a recent culture of the micro-organism, became infected via the nlimentary canal, and that the infected excreta were a cause of...

ferula persica, is the well-known species of the genus ferula in iran and has two varieties: persica and latisecta. they have both been extensively used in traditional medicine for a wide range of ailments. a great number of chemical compounds including sesquiterpene coumarins and polysulfides have been isolated from this plant. fresh plant materials, crude extracts and isolated components of f...
