説明
The endogenous levels of abscisic acid (ABA), indole-3-acetic acid (IAA) and gibberellins (GAs) in reproductive organs of satsuma mandarin (Citrus unshiu Marc. cv. Ozaki) were determined by gas chromatograph (GC)-electron capture detector, GC-mass spectrometry-selective ion monitoring and dwarf rice bioassay. Their probable roles are discussed.<BR>1. As anthesis approached, IAA concentration in styles and stamens did not change, while ABA concentration of styles increased six-fold. Until 39 days after flowering (DAF), the fresh weigth of fruitlets increased dramatically, while that of 'sepals' which included floral disks, sepals and receptacles increased a little.<BR>2. Fruitlets attained their maximum concentration of ABA 4 DAF and then declined rapidly. Its level remained much lower than that of 'sepals' from 7 DAF. IAA concentrations of fruitlets reached a maximum 7 DAF, and thereafter decrease; that in the 'sepals' increased from anthesis to 31 DAF surpassing that of fruitlets about 15 DAF.<BR>3. GAs concentrations of fruitlets continued to increase from 7 to 31 DAF, and decreased sharply 39 DAF.<BR>4. Because there was a sequence of peaks of endogenous ABA, IAA and GAs levels in fruitlets, it seemed that these hormones may play a sequential and synergistic role in the retention and growth of fruitlets.
