METHOD OF ANTICIPATORY FORECASTING OF FRUITS AND BERRIES STORABILITY DURING STORAGE Russian patent published in 2013 - IPC A01G7/00 A01F25/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture. In the method in carrying out biochemical analysis after ripening fruits and berries the fruits and berries storability is determined by determining the quantities of natural weight loss in the control fruits and berries under conditions of cold storage during the control period of time. The extreme values of their maximum and minimum are obtained, of which the minimum values correspond to the long-term storability, and the maximum - to the short-term in determining the activities of catalase and peroxidase or polyphenol oxidase, in control fruits and berries. The dependences of amounts of natural weight loss are obtained in control fruits and berries on the activities of catalase and peroxidase or polyphenol oxidase in them, and the anticipatory forecasting is carried out. The activity of catalase and peroxidase or polyphenol oxidase is determined in the wood tissues of grafts of fruit and berry crops, the dependences of amounts of natural weight loss are obtained in control fruits and berries under conditions of cold storage on the activities in the wood tissues of grafts, which are compared, respectively, with the dependences of amounts of natural weight loss in control fruits and berries on the activities of catalase and peroxidase or polyphenol oxidase in these fruits and berries. The comparison is carried out experimentally and on a single occasion. The extreme values of maximum and minimum activity of catalase or peroxidase or polyphenol oxidase in the wood tissues of grafts of fruit and berry crops are determined. The anticipatory forecasting is carried out by the extreme values of maximum and minimum of their activities. At that the fruits and berries collected from fruit and berry crops which activity of catalase in the wood tissues of grafts, respectively, has extreme values of the maximum, and which activity of peroxidase and polyphenol oxidase in the wood tissues of grafts has extreme values of the minimum, are due to long-term storage.

EFFECT: method enables to reduce the time of placement of fruits and berries for storage at the expense of an anticipatory forecasting of storability prior to their ripening, and extend the abilities of the method implementation.
