“…Maximum number of fruits per tree and yield recorded by paclobutrazol and uniconazole treated trees, might be due to the consequences of changes induced by growth retardant on overall physiology of mango trees viz., improved nutrient uptake, rapid and enhanced photosynthate re-allocation and altered hormonal balance. Similar findings were obtained by Upreti et al, (2013) and Anez (2009) in mango. Application of uniconazole (two sprays) with higher concentration of 1-1.5 g/l was observed to increase the fruit yield in mango cv.…”

“…In recent years, use of pesticides and fungicides, such as Paclobutrazol (Pbz), has shown a potential for improving crop drought tolerance24. In general, Pbz is used extensively to control insect and fungal attacks on crops via targeting the ecdysis of insects and fungal sterols25. The anti-gibberellin (GA) actions of Pbz have been well documented in plants; for example, plants treated with Pbz exhibit stunted growth due to reduced GA endogenous levels25.…”

Dwindling water resources combined with meeting the demands for food security require maximizing water use efficiency (WUE) both in rainfed and irrigated agriculture. In this regard, deficit irrigation (DI), defined as the administration of water below full crop-water requirements (evapotranspiration), is a valuable practice to contain irrigation water use. In this study, the mechanism of paclobutrazol (Pbz)-mediated improvement in tolerance to water deficit in tomato was thoroughly investigated. Tomato plants were subjected to normal irrigated and deficit irrigated conditions plus Pbz application (0.8 and 1.6 ppm). A comprehensive morpho-physiological, metabolomics and molecular analysis was undertaken. Findings revealed that Pbz application reduced plant height, improved stem diameter and leaf number, altered root architecture, enhanced photosynthetic rates and WUE of tomato plants under deficit irrigation. Pbz differentially induced expression of genes and accumulation of metabolites of the tricarboxylic acid (TCA) cycle, γ-aminobutyric acid (GABA-shunt pathway), glutathione ascorbate (GSH-ASC)-cycle, cell wall and sugar metabolism, abscisic acid (ABA), spermidine (Spd) content and expression of an aquaporin (AP) protein under deficit irrigation. Our results suggest that Pbz application could significantly improve tolerance in tomato plants under limited water availability through selective changes in morpho-physiology and induction of stress-related molecular processes.

Abstract. The flowering stage is one important stage in the mango fruit production. This stage is influenced by several environmental and internal factors. In subtropical regions, temperature is one important environmental factor in flowering process. The temperature at 18 °C during the day and 10 °C at night are needed to accelerate the flowering process. However, the temperature is not problem in tropic regions due to the temperature between two seasons (dry and wet season) is similar. The important factor that playing in flowering in tropic regions is drought stresses. At flowering stage of mango, the florigenic promoter (FP) is important promoter, while the vegetative promoter (VP) at the vegetative stage. Besides, the phytohormone also has a role in the flowering of mango. Phytohormones that play a role in flowering are auxin, cytokines, ethylene, and gibberellins. Furthermore, the increasing value of the C/N ratio could assist flowering initiation in mango plant.
