Chlorophyll (CHL) is present in many plant organs, and its metabolism is strongly regulated throughout plant development. Understanding the fate of CHL in senescent leaves or during fruit ripening is a complex process. The stay-green (SGR) protein has been shown to affect CHL degradation. In this study, we used the conserved sequences of STAY-GREEN domain protein (NP_567673) in Arabidopsis thal...

abstract in order to study the effect of planting density and branch pruning on growth, yield and quality of greenhouse muskmelon, a study has been conducted using a factorial experiment in a completely randomized design with three replications and three factors, including cultivar (galia-52 and mirella), branch pruning (1 and 2 branch per plant), and plant density (2, 2.4, 2.8 and 3.6 plants p...

in order to evaluate the effect of humic acid and zn on the grape yield and mineral concentration, a factorial experiment was conducted based on a randomized complete block design with three replications. the study was done on 20 years old grapevines in the farsan region from chaharmahal and bakhtiari province in 2013-2014. each of the factors, humic acid and zinc sulfate, were applied in three...

At least 14 ascorbate oxidase (AO) isoenzymes with isoelectric points in the range of pH 3 /10 have been identified and their expression profile studied in various Cucurbitaceae tissues and during development and ripening of melon fruit (Cucumis melo L. var. reticulatus). At least four acidic AO isoenzymes were mainly located in the apoplastic fraction, whereas 10 basic AO isoenzymes were found...

this study was conducted to evaluate the effects of exogenous polyamines, isopropyl ester, 2, 4-d and naphthalene acetamide application on yield and quality of date palm of ‘kabkab’ cultivar. the inflorescences sprayed with 2, 4-d isopropylester (0, 10, and 20 mg l-1), naphthalene acetamide (0, 80, and 120 mg l-1), putrescence and spermidine (0, 0.1, and 1.0 mm), three or six weeks after pollin...

To investigate effects of putrescine (Put) and humic acid (HA) on fruit yield and physiological attributes of okra (Abelmoschus esculentus L. 'Kano') under water deficit stress, a field experiment was conducted in split plot based on a randomized complete block design with three replications. Plants were exposed to three different irrigation regimes (33%, 66% and 100% ETc) and were treated with...
