Progression of the vegetation period and change of year are associated with variations in general climatic parameters, such as temperature, atmospheric pressure, humidity, radiation, precipitation, wind speed and others. Only limited knowledge is available about the effects of these parameters on the characteristics of quality of fruits especially those with successive ripening such as goji berry. In our study, fruits of goji berry were characterised based on physico-chemical properties within four different harvest periods, in two consecutive years. Based on the obtained results, it was found that the pomological characteristics were superior at the beginning of the production season, while the phytochemical properties were better at the end. Fruit length, width and weight characteristics were noted to decrease from the first harvest to the last by 21%, 18% and 33%, respectively, while the total anthocyanin, phenol and antioxidant activity properties increased by 264%, 48% and 105%, respectively. There was a decrease in fruit weight, fruit length and fruit width up to 15.9%, 18.3% and 6%, respectively and were directly associated with yield due to sink competition among fruits. Providing high ripening index that ensures more acceptable fruits, with high soluble solid content (SSC) and titratable acidity (TA) seems to be a very important breeding objective to meet consumer demands thanks to superior organoleptic quality. According to correlations, the synthesis of phenolic compounds increased in parallel with SSC rise and TA, which improved pomological properties too. It is thought that the obtained results may indicate the cultural processes and evaluation methods to be used for the harvested fruits.

枸杞果实结实时期和生长期对市场质量的影响

植被时期的进展和年份的变化与一般气候参数的变化有关，例如温度，大气压力，湿度，辐射，降水，风速等。关于这些参数对水果质量特性的影响的知识很少，尤其是那些连续成熟的水果，例如枸杞。在我们的研究中，枸杞的果实在连续两年的四个不同收获期中根据理化特性进行了表征。根据所获得的结果，发现在生产季节开始时的物候特性优良，而在结束时的植物化学特性则更好。水果长度 从第一次收获到最后一次收获，其宽度和重量特征分别下降了21％，18％和33％，而总花色苷，酚和抗氧化活性分别增加了264％，48％和105％。果实重量，果实长度和果实宽度分别下降了15.9％，18.3％和6％，这与果实之间的库竞争有关，与产量直接相关。提供出色的感官品质，提供高成熟指数以确保更可接受的水果，高可溶性固形物（SSC）和可滴定酸度（TA）似乎是满足消费者需求的非常重要的育种目标。根据相关性，酚类化合物的合成与SSC的上升和TA的增加同时增加，这也改善了其物性。
