Forchlorfenuron (CPPU): A Promising Plant Growth Regulator Augments Fruit Size, Fruit Weight, Quality and Yield of Kiwifruit (Actinidia deliciosa) cv. Hayward

Influence of Chemicals and Plant Bioregulators Application during the Time of Fruit Developmental Phenophase on Fruit Weight, Quality and Shelf-life of Mango (Mangifera indica. L)

“…Maximum TSS was noticed with CPPU (B4) (14.901) which was on par with the application of Ca (NO3)2 (B2)) (14.852) and KNO3 (B3) (14.633) however lowest TSS was noticed with control (B0) (11.968). "The higher TSS content with CPPU application might be attributed to a higher rate of photosynthates assimilation, as cytokinin is known to influence sink-source relations by mobilization of metabolites and nutrients to the developing fruits" [15]. The results are in accordance with that of Barkule et al [16] who observed "higher TSS content in sapota in Kallipati when treated with 6 ppm CPPU".…”

“…The application of chemicals at an early stage helps in reducing the acid content in the fruits and increases the TSS. These findings obtained in the present investigation can be compared to those obtained by Banyal and Banyal, [15] in kiwi cv. Hayward when treated with CPPU at petal fall.…”

“…These carbohydrates mainly contain sugar as major part of soluble solids and due to source to sink relationship, a higher percentage of total sugar may be found in treated fruits. These findings obtained in the present investigation can be compared to those obtained by Banyal and Banyal, [15] in "kiwi cv. Hayward when treated with CPPU at petal fall and Barkule et al [16] who observed higher TSS content in sapota in Kallipati when treated with 6 ppm CPPU 30 days before harvest".…”

“…Maximum TSS was noticed with the application of CPPU at 705 phenophase (B4T2) (17.300) compared to control and other treatments however the lowest TSS was noticed with control at 709 phenophase B0T3 (11.703). "The higher TSS content with CPPU application might be attributed to a higher rate of photosynthates assimilation, as cytokinin is known to influence sink-source relations by mobilization of metabolites and nutrients to the developing fruits" [15]. The application of CPPU during the 705 phenopnhase (T2) increases TSS synergistically compared to their individual application and control.…”

Impact of new generation plant growth regulators on fruit crops - A Review

“…At petal fall stage, the application of CPPU @ 5 ppm as dipping application obtained a significantly higher average fruit yield of 54.20 kg per vine. Similarly, maximum average fruit size (77.75 mm length and 53.74 mm diameter) and fruit weight (121.99 g) was recorded (Banyal, Banyal 2020). In another study of kiwi, fruits that were dipped for 10 seconds in an aqueous solution of 10 ppm CPPU at petal fall and again 30 days later grew 20-70 g larger than control fruits (Pramanick et al 2015).…”
