course is not finished, but the early season period until early June is very critical. Management expertise must be applied through to harvest to minimize fruit defects, enhance fruit


optimized. Notice that I did not say maximized. Too much water can affect shoot growth, and too little combined with excessive heat can stop shoot growth and shutdown fruit enlargement, to say nothing of the impacts of sunburn on fruit quality. The combination that I just mentioned causes stomate cells (the cells that open and close to regulate the flow of carbon dioxide and oxygen and humidity).
