Discernible Effect

KODA [9-hydroxy-10-oxo-12(Z), 15(Z)-octadecadienoic acid] has previously been isolated from Lemna paucicostata, and is a compound known to promote flowering in plants. In this study, the effect of KODA on flower production and spring shoot occurrence in mature satsuma mandarin (Citrus unshiu Marc.) trees was examined in the field. The application of KODA in the summer or autumn had no discernible effect on flower production in the following year. However, when applied in summer, it promoted spring shoot occurrence in the following year, regardless of the number of flowers produced. In addition, C-KODA, a KODA analog, was more effective at producing this effect than KODA. The results suggest that the application of KODA or C-KODA may regulate spring shoot occurrence to improve the imbalance between the number of flower-bearing and vegetative shoots that leads to alternate bearing in satsuma mandarin trees.

Carbohydrate Contents

The carbohydrate contents of the leaves of satsuma mandarin (Citrus unshiu Marc.) trees were altered before or during the low temperature flower induction period to determine the relationship between gross levels of carbohydrates and flower formation. Early removal of the fruit and girdling of the branches on either fruiting or defruited trees caused an accumulation of carbohydrates in the leaves and increased flower formation. Shading the trees resulted in a transient reduction in leaf carbohydrate levels and in a decrease in flower formation. Although a relationship between carbohydrate levels and flowering was consistently found, our results show that the gross levels of carbohydrates do not appear to limit flower formation in citrus.

Abstract This chapter deals with understanding the fruit sink by studying the floral development and structures; pollination, fertilization, fruit set and types; limitations of fruit growth; thinning effects on fruit growth, size and yield; spring temperature effects on fruit size; nut development and growth; and the condition of alternate bearing.
