ABSTRACT.
Flower induction and differentiation are complex phenomena not fully understood in pear trees. Ethylene is a plant hormone that seems to play an important role in flower induction. Exogenous ethephon (Eth) and naphthaleneacetic acid (NAA) applications have shown promising results to increase return bloom and yields in some pear cultivars. The objective of this study was to evaluate the effect of Eth and NAA on return bloom, yield and shoot length of 'Rocha' pear trees in southern Brazil. The study was performed during 2015/2016 and 2016/2017 growing seasons, using a five-year-old 'Rocha' pear orchard grafted on 'BA29' quince rootstock. Treatments consisted of untreated control, Eth 100 mg L‑1; NAA 5 mg L‑1; NAA 7.5 mg L‑1; NAA 10 mg L‑1; Eth 100 mg L‑1 + NAA 5 mg L‑1; Eth 200 mg L‑1 + NAA 7.5 mg L‑1; Eth 300 mg L‑1 + NAA 10 mg L‑1 applied at 40 + 60 + 80 days after full bloom (DAFB); Eth 150 mg L‑1 + NAA 7.5 mg L‑1 applied at 60 + 70 + 80 + 90 DAFB; and Eth 150 mg L‑1 + NAA 7.5 mg L‑1 sprayed at 40 + 60 + 80 + 100 DAFB. Shoot length in the year of application, return bloom, number of fruits tree‑1, yield (kg tree‑1 and Mg ha‑1) and average fruit weight the following season were assessed. Return bloom and yield were increased when trees were sprayed with Eth 100 mg L‑1 at 40 + 60 + 80 DAFB and Eth 150 mg L‑1 + NAA 7.5 mg L‑1 at 40 + 60 + 80 + 100 DAFB. NAA sprayed alone did not increase return bloom and yield. These results suggest that only ethephon was effective to increase return bloom, since NAA alone had no effect. Shoot length was reduced by all treatments compared to the untreated trees.

ABSTRACT. - Citrus sour rot caused by Geotrichum citri-aurantii is one of the most important postharvest diseases in citrus fruit, causing huge economic losses. Traditionally, it has been controlled by the postharvest application of guazatine and propiconazole fungicides, but restrictions in their use make it urgent to find an alternative for sour rot management. Natamycin, a common food preservative, and the organosulfuric compounds extracted from Allium species are safe food additives that control different foodborne pathogens. In the present study, the curative activities of commercial formulations of natamycin (Fruitgard Nat 20) and an Allium extract (PTSO: propyl thiosulfinate oxide; Proallium FRD®), were evaluated for the control of G. citri-aurantii in artificially inoculated lemon fruit. Trials in laboratory and in commercial conditions were carried out to explore the feasibility of including both compounds as part of a safe postharvest sour rot disease control strategy. Under controlled laboratory conditions, sour rot was significatively reduced by 500 mg L−1 of natamycin, 580 mL L−1 of PTSO and 290 mL L−1 of PTSO + 4% of a food coat, applied by immersion. Nevertheless, the maximum dose of PTSO (580 mL L−1) caused phytotoxicity on the fruit rind. In commercial drenching conditions, 290 mL L−1 of PTSO + 4% of a food coat reduced sour rot incidence similar to conventional treatment. In a packing line treatment, spray application of 500 mg L−1 of natamycin with a previous dip in sodium bicarbonate, resulted in nearly 70% reduction of disease incidence compared to conventional salt application. A second commercial experiment revealed that fruit drenching with 290 mL L−1 of PTSO + 4% food coat followed by an in-line cascade application of 500 mg L−1 of natamycin is completely effective for sour rot control after 20 days at 5 °C. Further exposure at room temperature for 7 d showed a 61% reduction in sour rot incidence compared to the control. Results revealed that natamycin and PTSO are promising tools for sour rot control used alone or combined as part of an integrated postharvest strategy. © 2022 Elsevier B.V.
