Critical frost temperatures for peach flower buds

Description

Critical frost damage temperatures for peach flower buds for the phenological stages between 'bud swelling' (B, 51 in Baggliolini and BBCH scales, respectively) and 'ovary surrounded by dying sepal crown' (I, 72). For use in combination with the example datasets Tudela_DW and Bigtop_reqs.

Usage

data("Tcrits_peach")

Format

A data frame with 7 observations on the following 2 variables.

LT_10

a numeric vector, frost temperature causing 10% kill

LT_90

a numeric vector, frost temperature causing 90% kill

Details

The 10% kill and 90% kill imply that 30 minutes at the indicated temperature is expected to cause 10% and 90% kill of the flower buds during the phenological stage. The dataset contains the critical temperatures for the same stages in the example dataset Bigtop_reqs.
