Abstract
SUMMARYIn Western Australia high root : shoot ratios found in apple trees would appear to represent an adaptation to the Mediterranean-type climate, which is characterized by high light intensity. Shading young Granny Smith trees significantly reduced root growth, the root : shoot ratio and leaf weight per unit area. Relatively light shading which reduced light intensity by 30% caused a slight increase in the weight of the shoots produced, which suggests that under these climatic conditions apple trees may tend to make less shoot growth than in a more temperate climate with a similar length of growing season. A reduction in starch accumulation was engendered by shading, especially in the below- ground parts of the tree.Alar at 2000 ppm reduced shoot but not root growth, and this effect tended to be accentuated by shading. Unirrigated and unfertilized trees also showed reduced shoot growth, but this effect was less pronounced in shaded than in exposed trees.
