Solution (By Examveda Team)

Maturity indices for harvesting apples are both T-stage and Mean heat units.

For the prediction of harvest maturity onset, most often utilized is the knowledge of the number of days from full flowerage (DAFB) into harvest time, which is typical for every cultivar and growing region, or, the length of time from development of the T-stage on young fruitlets to the start of their harvest maturity. In the T-stage the fruit's bottom part and stalk are in the position forming a shape similar to the letter T.
