Paclobutrazol (PBZ; IUPAC name: (2RS, 3RS)-1-(4-chlorophenyl)-4, 4-dimethyl-2-(1H-1, 2, 4-triazol-1-yl) pentan-3-ol) is a triazol derivative and an antagonist of gibberellins. It has been shown to inhibit shoot growth in various perennial fruit trees. Paclobutrazol application reduced the number of shoots, transforming trees into a more desirable, spur-type growth habit as the vegetative sink was reduced. This compound induces an early and intense flowering, diminishing vegetative growth and reducing the extension of buds, allowing for ripening and the initiation of apical buds inflorescence. Besides, it also increases fruit set, the years following application as a carryover effect. An increase in return bloom is a common response to paclobutrazol treatment and has been reported for various fruit crops. Paclobutrazol is widely used to advance harvest maturity in various fruit crops and it improves fruit quality in terms of accelerated colour development, delayed and synchronized fruit maturation and control of preharvest fruit drop. It is known to improve fruit physical and fruit chemical characteristics. Fruit calcium is increased for 2–3 years due to carry over effect. It helps in the maintenance of better fruit quality during storage and influences nutrient uptake in various fruit crops including stone fruits. It has been characterized as an environmentally stable compound in soil and water environments with a long half-life under both aerobic and anaerobic conditions.

“…If the stress is relieved during the phase of sugar accumulation, the fruit can accumulate higher sugar levels (i.e., TSS). Canopy architecture can also be altered to improve light distribution, to improve the uniformity of the TSS content within the fruit from a given tree (George et al, 1994;Crisosto et al, 1997). Growth retardants and ethylene inhibitors can also be used (McGlasson et al, 2004).…”

“…Byers (2003) also reported that ethephon promoted flower and fruit thinning, but with the disadvantages, relative to handthinning, of leaf loss and loss of the ability to thin to a specific size-class of fruit. George et al (1994) showed that, in combination with a high N rate, applying the growth retardant, paclobutrazol, increased the TSS content of (low-chill) peach fruit by approx. 1%.…”

“…by leaving these to ripen and completing its shelf life on trees. Similarly, water requirement and its irrigation scheduling (Boland et al 1993), distribution of light in the canopy of trees (Day, 1997;George et al 1994) and all other processes change the level of sugar and TSS of plum fruit.…”

Poor soil fertility due to continuous depletion of micronutrients is a major problem for the production of Prunus domestica L. Low level of soil organic matter and calcareous parent material decrease the bioavailability of these micronutrients to plum plants. Thus, less micronutrients uptake resulted in deterioration of plum fruit quality and decreased yield. On the other hand, balance and correct combination of micronutrients used as a foliar has potential to overcome this problem. Foliar application method provides plants a chance for rapid and easy uptake of micronutrients. Therefore, the present research was carried out to select the best combination of micronu-trients using foliar method. Aim of the study was to select a balanced combination of micronutrients for better production and improved quality of plum (Prunus domestica L., variety Fazal manai) fruit. Seven treatments in three replications were applied. Our results showed that the quality of fruit was significantly improved through the application of T6 micronutrients consortia. A significant increase in total soluble solids (16%), fruit yield per tree (92%) and fruit size (12%) validated the effectiveness of treatment T6 (Zn + Cu + Fe + Mn + B = 0.5% + 0.2% + 0.5% + 0.5% + 0.1%) over control. Application of treatment T6 also enhanced quality attributes, that is, juice acid-ity (22%), juice sugar (22%) and juice contents (16%), as compared to control. It is concluded that use of treatment T6 as a foliar application is a better approach for significant improvement in quality and yield attributes of plum in micronutrients deficient conditions.
