Description Usage Arguments Details Value References Examples

View source: R/GermPercent.R

Description

Compute the germination percentage or final germination percentage or germinability.

Usage

1
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.

Details

Germination percentage is computed as follows \insertCiteista_chapter_2015germinationmetrics. \loadmathjax

\mjsdeqn

GP = \fracN_gN_t \times 100

Where, \mjseqnN_g is the number of germinated seeds and \mjseqnN_t is the total number of seeds.

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

Value

The germination percentage (%) value.

# 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)
