Other claims from this paper (13)
- Intervention effect Surfactants enhanced suppression of Suntan shoot growth by a single paclobutrazol spray, especially Ortho X-77.
- Intervention effect Adding Sunspray 67E improved shoot growth control by three sequential paclobutrazol sprays in Cox.
- Intervention effect The concentration effect on shoot growth suppression was much greater with Sunspray 67E.
- Intervention effect Paclobutrazol sprays generally did not change the number of extension shoots, except for Suntan with Ortho X-77.
- Intervention effect Paclobutrazol sprays increased the proportion of shorter shoots at season end, enhanced by surfactants or higher concentration.
- Intervention effect A single paclobutrazol spray had no significant effect on total Suntan yield.
- Intervention effect Three paclobutrazol sprays increased Cox fruit abscission.
- Intervention effect Three paclobutrazol sprays reduced total Cox yield.
- Intervention effect Paclobutrazol treatments improved Cox fruit size.
- Intervention effect Paclobutrazol treatments increased weights of harvested Extra Class and Class 1 Cox fruits.
- Intervention effect Ortho X-77 caused severe russeting of Suntan fruit.
- Intervention effect Higher paclobutrazol concentrations slightly russeted Cox fruit.
- Intervention effect Adding Sunspray 67E to sprays slightly russeted Cox fruit.
