Abstract
Having no exact knowledge of most appropriate harvesting time in kiwifruit grown in different regions of Guilan province, as well as the low storage longevity of the fruits are the most important factors causing considerable reduction in both marketability and export affairs. In this study, the influence of fruit quality in term of harvesting time on the postharvest quality and food values of kiwifruit (Actinidia delicious cv. Hayward) was investigated. Based on the farmer’s experiences for each region, the harvesting time is chosen and fruits are harvested. Fruits are sorted and healthy ones are promptly stored at 0.5° C and relative humidity of 85-90% for two months. Results showed that the harvested fruits in most regions had no minimum maturity index at harvest time and usually are much more precociously harvested. Only those fruits with high total soluble solid (TSS) at harvest time could reach to an acceptable amount (more than 12.5 percent) of TSS after two months storage and also had less loss weight (P
