Hayward cultivar is one of the most important commercial kiwifruits (Actinidia deliciosa). It is
a woody fruit that grows in shrub or tree form in tropical and subtropical regions. It is widely grown in all countries that have favorable ecological conditions, namely Italy, France, the United States, South Africa, Chile, Italy, and Turkey. In its homeland, China, the average winter temperature is 0 °C, the annual average is 20–22 °C, and annual precipitation is 750 mm. Ideal
conditions are an average daytime temperature of 4.5 °C in winter and 13.30–13.9 °C in summer, 130–163 mm average annual precipitation, and 76–78% relative humidity. This study was carried out to establish the seasonal growth curves of kiwifruit. Together with, kiwi vines age effect was also evaluated. The trial was carried out in an orchard in Kocaeli, Turkey, 2.8
km from the sea at an altitude of 6 m (35°27.6′ N). Fruit measurements (width, thickness and
length) were taken throughout the growing season and draw growing lines. The kiwifruit growth curve was characteristically a double sigmoid that reflects two growing phases, fast and slow.
Kiwifruit development was affected by many factors such as temperature, light. Plant age was
also a factor that affects fruit quality based on how the accumulation of dry substance and sugar vary with age. Age also affected the fruit size and weight.
