The two commercially important fruiting cherries in North America are Prunus cerasus L. (sour) and P. avium L. (sweet). Carbon partitioning between individual organs, reproductive and vegetative, is dependent upon photoassimilate supply from photosynthesis and storage carbohydrate, as well as the ability of the translocation system to deliver these resources to sinks (Layne and Flore, 1995). Si...

Post-translational attachment of small ubiquitin-like modifier (SUMO), defined as SUMOylation, has emerged as a new mechanism of protein regulation in plant biology. In plant, SUMOylation has been shown to play crucial roles in a variety of biotic and abiotic stress responses. Recent work using viable mutants with defective SUMOylation have indicated an important role for SUMOylation in a wide ...

Introduction Soil salinity is an important limiting factor for crop yield improvement, which affects 5-10% of arable lands approximately 75-100 million ha worldwide, depending on estimates (Szabolcs, 1994; Munns, 2002). Most crops are sensitive to salt stress at all stages of plant development, from seed germination through vegetative and reproductive growth. Salt originates from marine geologi...

this study was conducted over a three-year period (1998, 1999 and 2000) to evaluate some drought tolerance indices and their relations with sugar yield in some sugar beet genotypes under early season drought and non-drought conditions. the experimental design was a split plot with a randomized complete block. the main plots consisted of two irrigation regimes: non-stress and water stress in ear...

Sweet Cayenne pepper is a nutrient-dense, sweet-tasting greenhouse vegetable that often faces water stress in dry areas, and optimizing growth with minimum consumption crucial. In this study, we investigated the impacts of amino acids (AAs) foliar application on reducing losses sweet cv. “Lombard” under conditions. The bushes were irrigated 3-day 6-day intervals simultaneously sprayed an AA fer...

Females of woody dioecious species usually devote more resources to reproduction than males. This may lead to a decrease in female survival and growth. The costs of reproduction, however, can be lightened through a number of mechanisms, as for example avoiding the temporal coincidence of reproduction and vegetative growth. The aim of this study was to evaluate whether males and females of P. le...

Faculty of Agriculture, University of Khartoum, 13314 Shambat, Sudan *Cell phone: +249912988847 ABSTRACT Previous studies report conflicting results regarding the sensitivity of cowpeas (Vigna ungiculata (L.) Walp.) to growth stage water deficits. A field study was designed to monitor the effects of water deficit imposed at different growth stages on yield and water use of cowpeas and to identi...

in order the the effect of biofertilizer and cut irrigation on growth of borage (borago officinalis) an experiment in split plot randomized based on complete block design with three replications in 1393 at the agricultural research station of roudehen islamic azad university done. treatments were first factor drought in four levels (control, stress at vegetative stage, stress at flowering stage...
