Effects of Crop Load on Water Stress, Fruit Quality, Yield and Flower Bud Formation on Root-Restricted Wase Satsuma Mandarin Trees Grown Indoors

A range of concentrations and timings of CPPU application were evaluated in attempt to identify situations in which fruit size, flesh firmness, and soluble solids could be increased while minimizing increased incidence of fruit asymmetry and reductions in flower bud formation and fruit surface red color on 'McIntosh' apples (Malus×domestica Borkh.). The greatest response to CPPU for most attributes evaluated occurred when it was applied at fruit size between 6 mm and 16 mm. The conclusion from this series of experiments is that differential response to CPPU could not be established by altering the time of application. The response to CPPU is linear with increasing concentration. Results suggested that use of 4 to 6 mg·L-1 CPPU on apples to increase fruit size was the maximum and appropriate range to use without causing fruit asymmetry. Chemical name used: N-(2-chloro-4-pyridyl)-N′-phenyl urea (CPPU)

Flower Bud Formation

The trend toward planting high density apple orchards continues. Closer tree spacing requires a greater degree of growth control to reduce shading and to prevent the decline in fruit quality and productivity as the planting become older. Chemical, rootstock, pruning, and management techniques will be reviewed that may control growth directly by reducing vegetative growth or indirectly through effects on increasing flower bud formation and fruit set. Pruning and management techniques will be discussed that can selectively reduce vigor in the tops of trees while allowing growth of the less vigorous lower portion of a trees to continue.

Flower Bud Formation

GA4+7 and GA4 substantially reduced russeting of `Golden Delicious' in four different years. There were indications that GA4 was more effective than GA4+7 at reducing russeting. The influence of gibberellins on flowering was variable and not always related to crop load. GA4 increased flowering in one experiment, had no influence in two experiments, and inhibited flowering in two experiments. GA7 either inhibited flowering or had no effect. There were indications that GA4 may partially reverse the inhibitory effect of GA7 on flowering in some instances.
