“…The highest carbohydrate content was found to be 2.62267 mg/g. This finding is partially agrees with previous reports on mango [35]. It is well known that paclobutrazol interferes with the hormone abscisic acid's production [36].…”

Girdling and paclobutrazol have been related with the effects on the photosynthetic capacity and carbohydrate content of plants. The physiological changes caused by these methods distress the growth and development of plants in general. A field experiment was carried out from August 2021 to June 2022 on 5 years of open-field Mangifera indica cv. Harumanis trees grown at Malaysian Agriculture Research and Development Institute (MARDI), Serdang, Selangor. The objective of this experiment was to understand the relationship between girdling, paclobutrazol application, combined methods and untreated trees on plant photosynthetic performances and carbohydrate content in the leaves. The treatments were performed on 1st December 2021, and the measurements of leaf gas exchanges and carbohydrate content were performed 4th weeks later on fully expanded leaves shoot, experiencing similar light exposure. In the study, the combination of girdling and paclobutrazol application resulted in a significant decrease in photosynthetic rate (Pn), stomatal conductance (gs) and transpiration rate (Tr) but significantly increase in intercellular CO2 concentration (Ci) and carbohydrate content.

“…This reduction in gas exchange during the flowering phase may be related to decreases in air temperature (Figure 1). A greater photosynthetic efficiency promotes a greater accumulation of carbohydrates, which can contribute significantly to flowering, fruiting and fruit production [23]. Singh et al (2017) [24], studying the effects of PBZ on the physiological characteristics of lychee, also reported higher A, E and gs during the vegetative phase when compared to the flowering stage.…”

O paclobutrazol tem sido amplamente utilizado para estimular o florescimento da mangueira, regulando o crescimento vegetativo, promovendo alterações na atividade fotossintética e na produção de fotoassimilados. Nesse contexto, objetivou-se com este trabalho avaliar o efeito de formas e doses de PBZ sobre as variáveis bioquímicas e fisiológicas da mangueira cultivar Tommy Atkins no semiárido brasileiro. O delineamento experimental foi em blocos casualizados em esquema fatorial 5 x 2 +1, sendo o primeiro fator, doses de paclobutrazol aplicadas via sistema de irrigação (0,5; 1,0; 1,5; 2,0 e 2,5 g i.a.m-1 linear de copa), o segundo duas fases de coleta (vegetativa e floração) e um tratamento adicional (controle), com a aplicação de uma dose na forma convencional (2,0 g.i.a.m-1 linear de copa aplicada manualmente a lanço), com quatro repetições. As variáveis analisadas foram os teores de açúcares solúveis totais, açúcares redutores, açúcares não redutores, aminoácidos totais, proteínas solúveis totais, fotossíntese líquida, condutância estomática, transpiração e temperatura foliar. A aplicação do PBZ via fertirrigação mostrou-se mais eficiente do que a aplicação convencional, possibilitando uma maior assimilação do produto pela planta e permitindo a redução da dose. A maioria das características bioquímicas, obtiveram os maiores valores com a aplicação de menores doses de paclobutrazol. O aumento das doses de paclobutrazol aplicadas via sistema de irrigação reduziram as trocas gasosas na mangueira cultivar Tommy Atkins.

“…Husen et al stated that the application of paclobutrazol 5 mL L -1 on a 5 yr old hybrid mango could accelerate during flowering, and increased the number of fruit yield [5]. Furthermore, Sarker et al stated that paclobutrazol could improve fruit yield, quality, and accelerate flowering in Amaprali varieties [2]. This result, was similar to the mangosten [11] and Tommy Atkins mango in Ethiopia [12].…”

“…Indonesian mango production was increase 2 203 793 t in 2017 to 2 624 791 t in 2018 and the rank is 6th in the world after India, China, Thailand, Pakistan and Mexico [1]. While, in 2011 mango production reached 2 129 608 t, while the exports were 1 485 t, and imports were 989 t. This gap in mango production and export volume indicated that Indonesia's mango is less competitive in the global market [2]. This condition is caused due to i) incompatibility of Indonesian mango quality specifications to world market demand, ii) there isn't available comprehensive seed testing system, which able to guarantee the product uniformity, iii) there isn't sustainable breeding program, iv) the farmers didn't apply technological innovation yet, and v) there isn't an institutional system which integrates mango agribusiness component.…”

The purpose of this study was to observe the technology of mango fruit production at off-season used growth regulators. The research was conducted with three treatments namely: i) Paclobutrazol dosage (control, 5 mL L–1 per tree, 10 mL L–1 per tree and 15 L–1 per tree). ii) Ethephon dosages (0 mL L-1 per tree, 400 mL L–1 per tree, 600 mL L–1 per tree and 800 mL L–1 per tree) that applied 1 mo after paclobutrazol addition. iii) Paclobutrazol (P) and organic fertilizer (F) application in combination as follows: (control, 5 mL + 10 kg, 10 mL + 15 kg, 15 mL + 20 kg) Randomized Completely Block Designed (RCBD) with five replications was used. The results indicated that i) Paclobutrazol application accelerated the flowering age, shortens the panicle length, and increased fruit yield of the tree. ii) Giving Ethephon accelerated the flowering period, enhanced both the panicles number and yields. The treatment of ethephones 600 mL L–1 produced the highest fruit weight, 182.60 kg, respectively iii) The Paclobutrazol and organic fertilizer application indicated significantly (p < 0.05) to the panicles number and the fruit weight yield is higher than the control.
