Mutagenic Effects

Determining the environmental safety of new synthetic plant growth regulators is an urgent problem. Spirocarbon derivatives were subjected to such determination by means of a specially developed system based on phytotests "germinated seeds". This system allows the values of biometric, cytological and biochemical parameters of the phytotest to determine the toxic, cytotoxic, genotoxic (mutagenic) effects and induction of molecular stress by the synthetic chemical substance being tested. This system was used to establish the biological properties of a new drug - a complex of spirocarbon with boric acid - in relation to five phytotests monocotyledons and dicotyledons plants. Phytotesting was performed in the spectrum of concentrations (10-7-10-2 mol/dm3) of this drug. It demonstrated either the absence or presence of a weak toxic effect on phytotests, which did not exceed 30%. The study showed that the plant growth regulator spirocarbon in combination with boric acid has growthregulating properties, the manifestation of which depends on the concentration of the drug and the species characteristics of plants. Only the maximum concentration (10-2 моль/дм3) of the tested drug is slightly toxic to plants. The obtained results testify to the biological efficiency and ecological safety of the synthesized drug. This allows us to recommend it for use in agricultural practice.

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.

Early Harvest

Abstract Experiments were conducted from 1996 through 2001 in Georgia, North Carolina, and Texas to determine peanut response to the commercial plant growth regulator Early Harvest® (a commercial mixture of cytokinin, gibberellic acid, and indole butyric acid). Early Harvest (applied in the seed furrow) or Early Harvest TST (applied as a dry seed treatment) followed by four foliar applications (four-leaf peanut, initial pegging, 14 d after initial pegging, and pod fill), was compared to non-treated peanut in five, 13, and three experiments in these respective states. Early Harvest did not affect pod yield or gross economic value of peanut regardless of location, cultivar, or edaphic and environmental conditions. These data suggest that a spray program consisting of Early Harvest most likely will not improve pod yield or gross economic value of peanut.
