Abstract

Taken together, these results suggest that ASM delays the senescence of apple fruit by regulating the sugar metabolism. © 2018 Society of Chemical Industry.

Postharvest acibenzolar‐S‐methyl treatment maintains storage quality and retards softening of apple fruit

“…The selected fruits were dipped in distilled water (control) and 100 mg/L ASM solution for 10 min according to previous reports (Ge, Wei, et al, ; Ge et al, ), with both control and samples treated with ASM containing 0.2 ml/L Tween 20. After air‐drying at room temperature (25 ± 2°C), all fruit were placed in trays and kept at 25 ± 2°C with a relative humidity of 40%–45%.…”

“…Acibenzolar‐S‐methyl (ASM), a salicylic acid analogue, has been universally used for controlling postharvest diseases of fruits and vegetables because of nontoxic, safe, and efficient to use. Studies have demonstrated that preharvest or postharvest ASM treatment could enhance disease resistance in apples (Ge, Wei, et al, ; Wei et al, ), pears (Ge et al, ), oranges (Moscoso‐Ramírez & Palou, ), bananas (Tang, Zhu, Li, Liu, & Irving, ), peaches (Liu, Jiang, Bi, & Luo, ), muskmelons (Ge et al, ; Ren et al, ), and mangos (Zhu, Cao, Wang, & Jiang, ), and reduce the incidence of diseases and therefore maintain quality. It has been demonstrated that ASM could regulate reactive oxygen species metabolism (Ge et al, ; Ren et al, ; Wei et al, ), phenylpropanoid pathway (Cao, Hu, Zheng, & Lu, ; Zhu et al, ), pentose phosphate pathway (Wei et al, ), while sucrose and energy metabolism (Ge et al, , , Ge, Chen, et al, ) were also induced by ASM.…”

Effects of trisodium phosphate treatment after harvest on storage quality and sucrose metabolism in jujube fruit

“…Thus, lower glucose level cannot provide sufficient substrate for respiratory metabolism. Previous studies indicated that NI activity was inhibited after NO and ASM treatment in apple fruit . The results acquired from peach fruit treatment with NO showed lower AI activity during storage at 25 °C …”

“…For determination of AI, NI, SS‐cleavage (SS‐c), SS‐synthesis (SS‐s) and SPS activities, the method described by Ge et al . was employed.…”

“…Acid invertase (AI), neutral invertase (NI), sucrose synthase (SS) and sucrose phosphate synthase (SPS) are main enzymes involved in sucrose metabolism . Studies have found that hot air and methyl jasmonate (MeJA), 6‐benzylaminopurine (6‐BA), ATP and acibenzolar‐ S ‐methyl (ASM) treatments could mediate sucrose metabolism in peach, loquat, pear and apple fruit to extend storage period or enhance disease resistance . However, the effects of TSP treatment on fruit quality and sucrose metabolism in harvested jujube fruit remain largely unknown.…”
