The effect of rootstocks on sugars, acids, carotenoids, chlorophylls, and ethylene of Satsuma mandarin (Citrus unshiu)
This study aimed to evaluate the effect of rootstocks on fruit sugars, organic acids, and carotenoids. The contents of sugars and organic acids in fruits were determined by HPLC. Total acidity (TA), total soluble solids (TSS), and pH value of the juice were also evaluated. Total carotenoids and chlorophylls contents were measured using a spectrophotometer. The content of ethylene in fruits was ...
متن کاملEthylene Production by Albedo Tissue of Satsuma Mandarin (Citrus unshiu Marc.) Fruit.
Isolated albedo tissue of Satsuma mandarin (Citrus unshiu Marcovitch, cv. Owari) fruit produced a large quantity of ethylene during incubation at 26 C in the dark. When sliced, albedo tissue began producing ethylene at an increasing rate until a maximum was reached after incubation for about 30 hours. Aged albedo discs which were capable of producing ethylene, actively converted l-[U-(14)C]meth...
متن کاملThe Effect of Rootstocks on the Peel Phenolic Compounds of Satsuma mandarin (Citrus unshiu)
The aim of this study was to determine total flavonoids and individually flavanone glycosides as well as antioxidant capacity in peel of Satsuma mandarin(Citrus unshiu) on different rootstocks. On other hand, the purpose of this study was to identify the rootstock that could produce the highest amount of flavonoids.Total flavonoids content was measured using aluminum chloride colorimetric meth...
متن کاملPhysical Changes in Satsuma Mandarin Leaf after Infection of Elsinoë fawcettii Causing Citrus Scab Disease.
Citrus scab disease is one of the destructive diseases that reduce the value of fruit for the fresh market. We analyzed the process of symptom development after infection with scab pathogen Elsinoë fawcettii in the susceptible satsuma mandarin leaves to observe the structural modification against pathogen. The cuticle and epidermal cells along with 3-5 layers of mesophyll tissue were degraded 1...
متن کاملTranscriptome and Metabolome Analyses Provide Insights into the Occurrence of Peel Roughing Disorder on Satsuma Mandarin (Citrus unshiu Marc.) Fruit
Roughing disorder (RD) is a significant quality barrier in citrus fruit, prevalent on easy-peeling mandarins. As RD is not yet well-understood, this study aimed to examine the changes and synergic molecular processes involved in peel RD. Peel with RD was induced by severely defruiting Satsuma mandarin trees. Morphology observations, RNA-sequencing, and targeted and untargeted metabolic analyses...
