growth stage, relative leaf elongation rate (RLER) was calculated as followed: where ln PH 2 and ln PH 2 are the natural logarithms of the PH at time one t 1 and time two t 2 , respectively. Plants were harvested from 4.5 m plots when an average of

present experiment, infusion or postpeeling treatment with 1% citric acid solution (pH = 2.30) reduced surface pH from 5.0 to 5.5 to ≈3.0 to 3.5, which would explain growth suppression of fast-growing spoilage bacteria ( Pao and Petracek, 1997 ). The

acidity, combined acidity, and the pH of brine samples were periodically measured in a titroprocessor (Metrohm 670; Herisau, Switzerland). Analyses of free and combined acidity were made by titrating up to pH 8.3 with 0.2 N OHNa, and down to pH 2.6 with 2

inheritance of flower color was attributed to the combined effect of anthocyanin pigmentation and pH, the latter being controlled by two independent codominant genes, Ph1 and Ph2 ( Griesbach, 1996 ). In morning glory, flower color varied from reddish
