Abstract
Tree trunks painted on the sunlit side with white exterior latex paint were found to be 30 C cooler than nonpainted trunks during midwinter in midlatitudes. The dependency of the cambium temp amelioration on wind speed and trunk diam is indicated through an argument based on convective transfer theory. The argument suggests that for trunks larger than 10 cm diam or for wind speeds less than 30 cm/sec around the trunk or both, the amelioration due to white paint may be greater than 30 C.
Abstract
‘Nittany’ is a ‘York Imperial’-type apple possessing outstanding processing characteristics. Fruit from the original seedling tree has been essentially free of corking; mild corking has been observed in some large fruits from propagules on size-controlling rootstocks. The fruit can be held in refrigerated storage for at least 6 months without appreciable shrinkage or loss of quality. The flesh oxidizes very slowly when exposed to the air and imparts a highly desirable yellow color to processed products.
