Novel exogenous calcium treatment strategies effectively mitigate physiological disorders in late season peach cultivars

Physiological and Taxonomical Studies on Some Peach Cultivars

This study was conducted during two successive seasons 2003 and 2004 by using twelve peach cultivars whether importedlow chill or originated as strains of local cultivar Meet Ghamr. Studied cultivars were either early-season ones (namely, Robin, Rubidoux, and Spring Time) or mid-season cultivars (namely, Florida Red, Fla 16/33, Fla 3/2, Desert Red, Bemto, and Hagazy) or late-season cultivars (n...

In-season calcium-spray formulations improve calcium balance and fruit quality traits of peach

Peach (Prunus persica) endopolygalacturonase cDNA isolation and mRNA analysis in melting and nonmelting peach cultivars.

Two distinct partial cDNAs, PRF1 and PRF3, similar in sequence to previously described polygalacturonases, were amplified from ripe peach (Prunus persica L. Batsch cv Flavorcrest) fruit cDNA by the polymerase chain reaction. PRF1-related RNA was present in fruit from early ripening at levels not detected by northern analysis. PRF3-related RNA was readily detectable in ripe fruit by northern ana...

Nematodes attacking cultivars of peach in north Carolina.

Criconemoides xenoplax and Meloidogyne incognita were the nematode species most frequently associated with peach in North Carolina. Other nematodes often found in high numbers on that crop were Pratylenehus vulnus, Helicotylenchus spp., Trichodorus christiei, Xiphinema amerieanum and Tylenchorhynchus claytoni. P. vulnus and P. penetrans reproduced well on rootstocks of 21 peach cultivars tested...

Evaluating Foliar Application of Calcium Nitrate, Calcium Chloride and Boric Acid on Physiological Disorders of ‘Kaleh - Ghoochi’ Pistachio

Pistachio suffers from some physiological disorders such as fruit abscission, endocarp lesion, blankness, non-split, early-split and deformed nuts. In this experiment, the effects of calcium nitrate (2 gr/lit), calcium chloride (2 gr/lit), boric acid (200 ppm) and their combination treatments were investigated on physiological disorders of ‘Kaleh-Ghoochi’ pistachio. Foliar application was appli...
