The researchers studied how the quality of pomegranates changes as they grow, and how this is related to the leaves of the plant. They looked at two different types of pomegranates and found that as the fruit develops, the sugar content increases, while the acidity decreases. One type of pomegranate had more vitamin C and anthocyanins than the other. They also found that the sugar in the fruit is linked to the production of anthocyanins, which give fruits their color. The leaves of the plant also change during fruit development, with some compounds decreasing and others increasing. Overall, the quality of the fruit and the characteristics of the leaves were different between the two types of pomegranates.
