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...

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...

Abstract The effect of temperature on the ability 2-chloroethylphosphonic acid (ethephon, ETH) and 1-aminocyclopropane carboxylic (ACC) to induce ethylene production in fruitlets abscission leaves when applied at postbloom (~15 mm fruit diameter) was studied using 5-year-old ‘Sweet Lady’/Rootpac-20 peach [ Prunus persica (L.) Batsch] trees kept pots environment-controlled growth rooms. ETH 150 ...

The plants of Prunus mostly bloom in early spring, and the flowers various species possess their individual floral scent characteristics; mume, especially, can volatilize a large amount benzenoid compounds into air during flowering phase. In order to elucidate molecular basis differences volatile capacity aromatic substances among flowers, endogenous headspace components expression ABCG genes w...

Peach (Prunus persica (L.) Batsch) is a typical shallow-rooted fruit plant with high respiratory intensity and oxygen demand, which makes it highly susceptible to oxygen-deficient soil conditions resulting from waterlogging. Rootstock waterlogging resistance essential the performance of cultivated peaches under stress. In comparison Prunus var. (‘Maotao’, M) davidiana (Carr.) C. de Vos (‘Shanta...
