Abstract:

An experiment was conducted to ascertain the effect hydrogen cyanamide (HCN) @ 2 per cent a.i and abscisic acid (ABA) on time of ripening and fruit quality of Flame Seedless grapes. The treatment (T6 – HCN @ 2% + ABA @ 100 ppm) had advanced the time of ripening by 9-days as compared to untreated (control). Likewise, the maximum bunch weight (384.67 g) was recorded in a treatment in which 2 per cent HCN + 100 ppm of ABA was applied at veraison stage. Grapevines treated with 2 per cent HCN + 100 ppm ABA + 400 ppm ethephon had lowest uneven colour of berries/bunch (16.78 %). The maximum TSS was also recorded in T3 (HCN 2 % + 100 ppm ABA), while lowest acidity was recorded in treatment T6 (HCN 2 % + 100 ppm ABA + 400 ppm ethephon). The maximum (41.87 mg/100 g) anthocyanin content was recorded in treatment T3 i.e. HCN (2 %) + 100 ppm ABA. The present study suggested that pre-harvest treatment of 2 per cent HCN (at end of December) + 100 ppm ABA (at veraison stage) was helpful in advancement of ripening and improvement in fruit quality in Flame Seedless grapes.
