Anthocyanin accumulation in apple and peach shoots during cold acclimation
نویسندگان
چکیده
Experiments were conducted to investigate the effects of low temperatures on anthocyanin accumulation in apple and peach shoots. The anthocyanin concentration in both the apple and peach shoots increased rapidly during cold acclimation reaching the peak value in early December. The anthocyanin might be accumulated in shoots as a result of leucoanthocyanidin conversion. When apple and peach shoots collected in mid-January were subjected to various subzero temperature treatments, their anthocyanin concentration tended to increase and reached the peak value near the killing temperature, whereas the leucoanthocyanidin concentration was reduced as the temperature decreased. # 2000 Elsevier Science B.V.

Effect of postharvest oxalic acid treatment on ethylene production, quality parameters, and antioxidant potential of peach fruit during cold storage.
The effects of postharvest oxalic acid (OA) treatment on ethylene production, fruit quality, bioactive compounds and antioxidant activity of peach fruit, were examined. Fruits were treated with oxalic acid immediately after harvest and stored at 1° C and 90% relative humidity for 28 days. The oxalic acid treated peach fruit exhibited significantly lower levels of ethylene production, pH, total ...
متن کاملOverexpression of a peach CBF gene in apple: a model for understanding the integration of growth, dormancy, and cold hardiness in woody plants
The timing of cold acclimation and deacclimation, dormancy, and budbreak play an integral role in the life cycle of woody plants. The molecular events that regulate these parameters have been the subject of much study, however, in most studies these events have been investigated independently of each other. Ectopic expression of a peach CBF (PpCBF1) in apple increases the level of both non-accl...
متن کاملSuppression subtractive hybridization identifies genes induced in response to UV-B irradiation in apple skin: isolation of a putative UDP-glucose 4-epimerase.
Suppression subtractive hybridization (SSH) successfully identified 11 cDNAs in apple skin with highly induced expression as a result of ultraviolet (UV)-B irradiation. Apart from three putative flavonoid biosynthetic genes, chalcone synthase (CHS; A5C), flavanone-3-hydroxylase (F3H; B5F), and flavonol synthase (FLS; D1F), five clones (A1H, A10E, B11G, D5F, and D11H) were induced by low tempera...
متن کاملRed colouration in apple fruit is due to the activity of the MYB transcription factor, MdMYB10
Anthocyanin concentration is an important determinant of the colour of many fruits. In apple (Malus x domestica), centuries of breeding have produced numerous varieties in which levels of anthocyanin pigment vary widely and change in response to environmental and developmental stimuli. The apple fruit cortex is usually colourless, although germplasm does exist where the cortex is highly pigment...
متن کاملEffects of orchard host plants (apple and peach) on development of oriental fruit moth (Lepidoptera: Tortricidae).
Studies were designed to examine the effects of host plants (apple, Malus domestica Borkh., and peach, Prunus persica L.) on the development of oriental fruit moth, Grapholita molesta (Busck) (Lepidoptera: Tortricidae). Oriental fruit moth larvae developed faster on peach than on apple, both on fruit as well as on growing terminal shoots. On fruit, these differences were shown to cause signific...
