“…However, few studies investigated ethylene production in leaves, buds, flowers, or other vegetative material from tree crops. Examples are GC detection of ethylene in leaves of citrus (Tudela and Primo- Millo, 1992 ), in shoot portions of apple ( Sanyal and Bangerth, 1998 ), and in floral buds and leaves of mango ( Bindu et al, 2017 ), peach ( Liu et al, 2021 ) and litchi ( Cronje et al, 2022 ) trees. However, most of these studies only provided limited information on the sampling and analysis techniques used to successfully reproduce the techniques for application in other crops with similar plant organs.…”

Ethylene is an important plant hormone that is involved in the regulation of numerous processes in plant development. It also acts as a signaling molecule in response to biotic and abiotic stress conditions. Most studies have investigated ethylene evolution of harvested fruit or small herbaceous plants under controlled conditions, but only a few explored ethylene release in other plant tissues, such as leaves and buds, particularly those of subtropical crops. However, in light of increasing environmental challenges in agriculture (such as temperature extremes, droughts, floods, and high solar radiation), studies on these challenges and on potential chemical treatments for mitigating their effects on plant physiology have become more and more important. Thus, adequate techniques for the sampling and analysis of tree crops are needed to ensure accurate ethylene quantification. As part of a study on ethephon as a mitigating agent to improve litchi flowering under warm winter conditions, a protocol was developed for ethylene quantification in leaf and bud tissue of litchi following ethephon application, taking into account that these plant organs release lower ethylene concentrations than fruit. At sampling, leaves and buds were placed in glass vials of appropriate sizes for the respective plant tissue volumes and allowed to equilibrate for 10 min to release possible wound ethylene before incubating the samples for 3 h at ambient temperature. Thereafter, ethylene samples were aspirated from the vials and analyzed using a gas chromatograph with flame ionization detection, the TG-BOND Q+ column for separation of ethylene, and helium as the carrier gas. Quantification was achieved based on a standard curve derived from an external standard gas calibration with certified ethylene gas. This protocol will also be appropriate for other tree crops with similar plant materials as study foci. It will enable researchers to accurately determine ethylene production in various studies investigating the role of ethylene in general plant physiology or stress-induced plant responses following a range of treatment conditions.

The flowering induction in mango (Mangifera indica L.) orchards is an agricultural practice carried out on tropical regions to obtain fruits out-of-season looking to reach better sale prices. The objective of this research was to evaluate the effect of potassium (PN), ammonium nitrate (AN) and paclobutrazol (PBZ) on flowering induction and fruit production in mango cv. Tommy Atkins. The experiment included fourteen treatments with 2, 4, and 6 % PN, and 2, 3 and 4 % AN applied in combination with PBZ (1 g of a.i. m-1 of canopy diameter), paclobutrazol alone (1 g of a.i. m-1 of canopy diameter), and a control (water), which were arranged in a completely randomized design with three replicates. Results show that floral induction and fruit production were improved: PBZ followed by foliar application PN 2 %, 4 % or 6 % induced flowering 16 days after treatments. Likewise, the major number of emerged panicles were obtained with PBZ + PN 6 %. An increase on fruit weight and size reduction was observed at harvest. PBZ followed by foliar application of nitrates induced flowering and enhanced the number developed panicles in mango cv. Tommy Atkins.RESUMENLa inducción floral en mango (Mangifera indica L.) es una práctica agrícola común en regiones tropicales, tendiente a obtener frutos fuera de temporada para lograr mejores precios de la cosecha. Este trabajo tuvo como objetivo evaluar el efecto de tratamientos de nitrato de potasio (PN), nitrato de amonio (AN) y paclobutrazol (PBZ) sobre la inducción floral y producción de fruto en mango cv. Tommy Atkins. Los tratamientos con PN al 2, 4, y 6 % y AN al 2, 3 y 4 % fueron aplicados solos o combinados con PBZ (1 g de i.a. m-1 de diámetro de copa), PBZ solo y un testigo (agua) bajo un diseño completamente al azar, con tres repeticiones. Se midieron variables de inducción floral y producción de fruto. Los resultados muestran que aplicación foliar de PBZ seguida de PN (2 %), (4 %) o (6 %) indujeron floración 16 días después del tratamiento. El mayor número de panículas emergidas se obtuvieron con PBZ + PN 6 %. Se observó una reducción de peso y tamaño de fruto a la cosecha. El PBZ seguido de aplicaciones foliares con NP y AN induce floración y aumenta el número de panículas desarrolladas en mango cv. Tommy Atkins.

“…In another study, Upreti et al, (2014) reported increase in carbohydrates as the result of upregulation in certain carbohydrate metabolizing enzymes by paclobutrazol responsible to floral bud initiation in mango. Further, polyaminesethylene balance has been reported by Bindu et al, (2017) crucial for floral bud growth in mango, with high polyamines and reduced ethylene under paclobutrazol contributory to increased flowering.…”
