METHOD OF FORECASTING YIELD BY COMPATIBILITY FACTORS OF GRAFT-ROOTSTOCK PAIRS OF GRAPE

摘要

FIELD: agriculture, in particular, viniculture. SUBSTANCE: method involves measuring width of phloem and xylem tissues and distance from conventional center to cambial layer on ventral and hollow sides of graft and rootstock sprouts. Quotient of rootstock factors and graft factors of compatible pair is within the range of 0.91-1.14. EFFECT: increased efficiency in predicting yield by obtaining precise data. 2 tbl
