PHYSIOLOGY OF RESISTANCE OF POTATO VARIETIES TO SOFT ROT DISEASE——Ⅰ.RELATIONSHIP BETWEEN THE CONTENT OF FREE AMINO ACIDS IN TUBERS AND THEIR RESISTANCE
Great changes in amino acids(FAA) in potato tubers were observed during coldstorage over 4 months.The patterns of changes varied with varieties and could not be re-lated to variety resistance.FAA contents in tubers of 17 varieties were also not associ-ated with the level of resistance.The fluctuation of FAA content in Kexin 4(more suscep-tible)pretreated at lower temperature or partial anaerobic was positively related to thatof susceptibility,while in Kexin 9 (more resistant) the FAA fluctuation was positiv...
