Abstract
This study has been conducted to investigate the effect of gibberellic acid and several plant growth regulators on growth and quality of fruits in triploid grapes. The gibberellic acid (GA₃, 50 and 100 ㎎ L?¹) and GA₃ (100 ㎎ L?¹) with other plant growth regulators such as streptomycin (SM, 200 ㎎ L?¹), mepiquat chloride (MC, 880 ㎎ L?¹), and N-(2-chloro-4-pyridyl)-N′-phenylurea (CPPU, 2.5 ㎎ L?¹) were treated to grapes. There were no noticeable differences in fruit growth and quality of grapes when only GA₃ were treated as 50 or 100 ㎎ L?¹ in all of triploid hybrid grapes. Statistically significant effects on the enlargement of cluster weight and berry size were shown in ‘KB0120’, ‘KN200110’, ‘KS20015’, ‘KTS011’, ‘YRB9803’ triploid hybrids treated with 100 ㎎ L?¹ GA₃+ 2.5 ㎎ L?¹ CPPU. In combined treatment of 100 ㎎ L?¹ GA₃ and 2.5 ㎎ L?¹ CPPU treatment, harvest time was delayed for up to 10 days. The sugar content and organic acid varied depending on the hybrid conditions. The decline of total sugar content was the highest in 100 ㎎ L?¹ GA₃+ 200 ㎎ L?¹ SM for all hybrid grapes. There were no differences between 100 ㎎ L?¹ GA₃+ 2.5 ㎎ L?¹ CPPU and GA₃ alone treatment in organic acid and total sugar contents. The results indicated that combined berry treatment of 100 ㎎ L?¹ GA₃ and 2.5 ㎎ L?¹ CPPU seem to be useful for the production of high quality fruit in triploid hybrid grapes.
