significantly higher than water. Marketability. Following one week of storage, exterior and interior percent marketability of fruit from plants receiving Ca versus water was not significantly different. Following two weeks storage, Texas-grown fruit exterior and interior marketability from plants receiving Ca applications was significantly better than water (Table 4). But in California-grown fruit, Ca treatments (versus water) were not statistically different for either exterior or interior percent marketability. Sugars and taste. Percent soluble solids concentration, within each growing location for all fruit was similar. Between locations the concentration of sugars was lower in Texas than California-grown fruit. With few exceptions, consumer preference for all fruit, regardless of location, ranged from like to like extremely. Statistically, significant differences were observed between certain treatments, but across all locations or storage times, no treatments were consistently different. Consumers usually gave fruit from Ca-treated plants the best rating, but it was never always significantly better than fruit from plants receiving water.
