calculate_psri: Calculate Plant Stress Response Index (PSRI)

Description

This function calculates the Plant Stress Response Index from time-series germination data with optional radicle vigor integration.

Usage

calculate_psri(
  germination_counts,
  time_points = c(3, 5, 7),
  total_seeds,
  species,
  radicle_summary = NULL,
  diseased_counts = NULL
)

Value

A list containing PSRI components and metrics

Arguments

germination_counts

Numeric vector of cumulative germination counts at each time point (length 3 for days 3, 5, 7)

time_points

Numeric vector of time points in days (default: c(3, 5, 7))

total_seeds

Integer, total number of seeds in the replicate

species

Character string, species name for identification

radicle_summary

Optional list containing radicle data

diseased_counts

Optional numeric vector of diseased seed counts
