Method for factor analysis of ontogenesis of registration leaves of a tree

摘要

1. A method for factor analysis of the ontogenesis of reference leaves of a tree, including laying a substrate with a white surface from below on a measured sheet, and on top of the sheet put a transparent palette for cartographic measurements, the longitudinal axis of the plant sheet being combined with one of the palette grid lines, then the sheet through a transparent palette they take photographs with the grid, after which the photograph is placed in the computer’s memory, and the sheet parameters are measured on the cells of the palette grid in an enlarged image of the sheet, characterized in that the pairs are measured meters of registration leaves after their numbering without cutting, they are carried out during the growing season from the beginning of simultaneous budding of buds to the fall of each registration sheet, for the possibility of statistical modeling by identifying stable biotechnical patterns, photographing each accounting sheet separately is carried out at least seven times during the growing season, and each photographing of all registration leaves are carried out at approximately the same time of the day; maximally, out of all measurements during the growing season the nominal values of the parameters of the reference leaves, then the vegetation period and the maximum values of the parameters of the reference leaves in the form of the maximum length, maximum width, maximum perimeter and maximum area are taken as mutually dependent factors; they make up a table of initial data for statistical modeling with columns indicating factors in them and lines indicating the number of the registration sheet, and then according to the compiled table of source data, conduct factor analysis in four stages: 1) identifying the pattern
