INVESTIGATION METHOD OF DAY-AND-NIGHT RHYTHM OF CYTOGENETIC INDEXES OF WOODY PLANTS Russian patent published in 2009 - IPC A01G7/00 

FIELD: agriculture.

SUBSTANCE: as per the method material is fixed for cytological tests, microslide is prepared, cytogenetic indexes are measured. Graph is constructed: index - time, based whereon daily rhythm of the index is evaluated. Then single experimental value of the index under study is derived at any of the investigated hours, other values of the index at any hour of the day are calculated from the expression: where N - polynom degree, j=1…M, where M - number of view points, a_i - polynomial coefficients, calculated within the least square method, y_j - values of experimentally derived cytogenetic indexes, x_j - observation points in time, y_n - value of the predicted cytogenetic index, x_n - prognoses point in time.

EFFECT: reduced duration of the cytogenetic test.
