Abstract

Siam orange (Citrus nobilis L.) is widely propagated by grafting because it produces seedlings identical to the parent plant and shortens the vegetative phase. The success and vigor of grafted seedlings can be improved by applying plant growth regulators (PGRs) of natural or synthetic origin, yet different PGR types may produce different responses. This study aimed to determine the effect of different PGR types on the growth and graft union of grafted Siam orange seedlings and to identify the most effective type. The research was conducted at CV. Diplomat Kantor Barat, Batu City, Indonesia, from March to July 2024, using a non-factorial Randomized Block Design with nine treatments and three replications: Z0 (control), Z1 (young coconut water), Z2 (old coconut water), Z3 (shallot extract), Z4 (mung bean sprout extract), Z5 (NAA), Z6 (BAP), Z7 (IBA), and Z8 (GA₃), each at 200 ppm. The observed variables were survival percentage, shoot height, number of leaves, leaf area, shoot diameter, and graft union. Data were analyzed using ANOVA followed by the Honestly Significant Difference test at 5%. The results showed that GA₃ (Z8) produced the highest shoot height, number of leaves, leaf area, and shoot diameter, owing to its higher gibberellin content. Synthetic PGRs generally outperformed natural PGRs and the control, while NAA (Z5) and IBA (Z7) produced the best graft union, indicated by a minimal gap between scion and rootstock due to their high auxin content.

Abstract

Shoot pruning (topping) is a key technique in melon (Cucumis melo L. var. makuwa Makino) cultivation to optimize source-sink balance by suppressing apical dominance, yet its effectiveness is highly dependent on pruning time and node position. This study evaluated the interaction and independent effects of pruning time and node position on the growth and yield of Chamoe melon grown in a smart greenhouse. A Completely Randomized Factorial Design was applied at the Korean Smart Greenhouse, BBPP Ketindan, Malang (September–December 2025), with two pruning times (33 and 40 DAT) and three node positions (17th, 20th, and 23rd above the fruit), comprising six treatment combinations and four replications. Parameters included leaf area, fruit sweetness, fruit diameter, fresh fruit weight, moisture content, and organoleptic quality (aroma, texture, taste), analyzed by ANOVA and HSD test at 5%. Significant interactions were found for leaf area and fresh fruit weight: pruning at 33 DAT on the 20th node produced the highest leaf area (176.47 cm²), while pruning at 40 DAT on the 20th node yielded the highest fresh fruit weight (632.81 g fruit⁻¹). Fruit sweetness showed no significant interaction, but was independently affected by both factors: pruning at 40 DAT produced the highest sweetness (10.90 °Brix), and pruning at the 20th node produced the highest sweetness (11.47 °Brix). Pruning time significantly affected taste preference, with 40 DAT yielding higher scores, whereas fruit diameter, moisture content, aroma, and texture showed no significant differences among treatments.
