Qualitative Characteristics

Fruit yields of traditional navels like Washington Navels are lower as compared to other sweet oranges due to low fruit set and quality problems like creasing. Effect of plant growth regulator and Potassium (GA3 and KNO3) alone and in combination were tested in Sargodha, Punjab conditions at full bloom stage of Washington navel oranges. Impact of these treatments was tested on fruit yield, quality and to reduce the physiological disorder; incidence of creasing. Fruit set and yields were increased over non-treated trees, while combine treatment of GA3 and KNO3 (GA3 25% and KNO3 2%) had best results in fruit yields and quality i.e. fruit weight, size, TSS, acidity and other qualitative characteristics of the fruit. Creasing was effectively minimized by spraying plant in combination of GA3 and KNO3, thus reducing the quantitative and qualitative post-harvest fruit losses.

Heat Tolerant

An investigation was undertaken with a view to observing the performance of two heat-tolerant varieties of tomato under polytunnel with and without plant growth regulator application during the summer rainy season. The present study was laid out in a Randomized Completely Block Design (RCBD) with three replications. Two heat-tolerant tomato varieties Bangladesh Agriculture Research Institute (BARI) Tomato-4, and BARI Hybrid Tomato-4 with and without plant growth regulator applications were included in this experiment. The larger fruit set percentage (42.52%) was observed from BARI Hybrid Tomato-4 which was also larger in case of pollen viability (42.75%), the figure of fruits every cluster (3.01), figure of fruits every plant (12.70), and yield every plant (460 g). Better yield was showed in spraying of 4-CPA at 40 ppm concentration in respect of percent fruit set (45.38%), figure of fruits every plant (16.45), and yield (39.39 t/ha) under high-temperature condition. In integrate treatment, BARI Hybrid Tomato-4 with 40 ppm 4-CPA performed a significant role in the figure of fruits every cluster (3.41), figure of fruits every plant (22.48), figure of fruits every plot (144.00), yield every plant (621.68 g), yield every plot (15.23 kg) and above all fruit yield (50.57 t/ha). This indicates that there is a bright scope of tomato production during summer through with and without plant yield regulator application, though the application of plant growth regulator had a positive impact on tomato yield.

Harvest Delay

The effects ReTain Plant Growth Regulator (830 g in 1000 L water/ha) applied to a commercial block of 'Arctic Snow' nectarines 7 days before the first harvest was assessed in relation to harvest delay, fruit size, fruit quality (flesh firmness and brix), as well as the quality of the fruit following export to Taiwan. The untreated block (0.87 ha) and the ReTain-treated block (1.0 ha) were harvested according to the orchard's standard maturation criteria of background colour, size and percent blush colour. Based on picking schedules, the maturation of the ReTain block was delayed by 2.75 days (P<0.05). The fruit continued to grow during this delay and resulted in a 12.3% increase in yield and an increase of 393 packed cartons/ha. There were more (P<0.001) cartons of ReTain-treated fruit packed in grade sizes 69–78 mm diameter and less of smaller size classes (51–66 mm) compared with untreated fruit. The increase in both the number of cartons of class 1 fruit and fruit size on the ReTain block resulted in a Return on Investment (ROI) of 14.7 : 1 with an additional net return of AU$17 655/ha over the untreated block. There was a correlation between fruit size and flesh firmness with larger fruit being firmer than smaller fruit (P<0.001), however, packed ReTain-treated fruit was 3.2 N firmer on average (P<0.001) than packed untreated fruit for all size grades and from all harvests and packs. Brix levels increased (P<0.001) with fruit size but there was no difference (P = 0.568) between ReTain-treated fruit and untreated fruit. Two containers of fruit (early and late picks) were exported to Taiwan. The containers held a temperature of 0.5–2.0°C for the 14–15 day transit time from Australia to Taiwan. ReTain-treated fruit in both containers was 1.7 N firmer (P = 0.022) than untreated fruit upon arrival in Taiwan. After ambient storage (23°C) of fruit from container 1 for 45 h, fruit firmness declined (P<0.001) from an average of 65.7 to 43.2 N and there was no difference (P = 0.826) between treated or untreated fruit. It is concluded that ReTain application to 'Arctic Snow' nectarines can increase financial returns to growers through increased fruit size and quality benefits as well as maintain a higher flesh firmness following export.
