germinationmetrics (version 0.1.4)

GermPercent: Germination percentage

Description

Compute the germination percentage or final germination percentage or germinability.

Usage

GermPercent(germinated.seeds, germ.counts, total.seeds, partial = TRUE)

Arguments

germinated.seeds

Number of germinated seeds

germ.counts

Germination counts at each time interval. Can be partial or cumulative as specified in the argument partial.

total.seeds

Total number of seeds.

partial

logical. If TRUE, germ.counts is considered as partial and if FALSE, it is considered as cumulative. Default is TRUE.

Value

The germination percentage (%) value.

Details

Germination percentage is computed as follows ista_chapter_2015germinationmetrics.

GP = N_gN_t 100

Where, N_g is the number of germinated seeds and N_t is the total number of seeds.

The value of N_g can be either specified using the argument germinated.seeds or is computed from the germ.counts argument.

Examples

# NOT RUN {
x <- c(0, 0, 0, 0, 4, 17, 10, 7, 1, 0, 1, 0, 0, 0)
y <- c(0, 0, 0, 0, 4, 21, 31, 38, 39, 39, 40, 40, 40, 40)

# From partial germination counts
GermPercent(germ.counts = x, total.seeds = 50)

# From cumulative germination counts
GermPercent(germ.counts = y, total.seeds = 50, partial = FALSE)

# From number of germinated seeds
GermPercent(germinated.seeds = 40, total.seeds = 50)
