Time-to-event analysis to evaluate dormancy status of single-bud cuttings: an example for grapevines.

ABSTRACT:

Background

The reduced growth of plants during the winter causes a lack in the perceptibility of the phenological events making challenging the study of dormancy. For deciduous crops, dormancy is generally determined by evaluating budbreak of single-node cuttings that are exposed to conditions suitable for growth. However, the absence of a statistical basis for analyzing and interpreting the budbreak behavior evaluated as the percent budbreak, the average time to budbreak and the time to reach 50% budbreak, has caused inconsistent and contradictory criteria to identify the dormancy status of different deciduous crops.

Results

In this study, a method was developed to analyze the duration between sampling and budbreak of single-node cuttings and to estimate the dormancy status
