2.4.3. Seed vigour
The vigour indices were evaluated simultaneously with standard
germination test, according to the protocol proposed by
Abdul-Baki and Anderson (1973). After the germination test (fourteen
days), 10 normal seedlings from each replication of both
treatments were selected at random and their average seedling
length (plumule tip to root tip) was recorded. The Vigour Index
was calculated using the formula as mentioned below:
Vigour Index = Germination (%) X Average seedling length of 10
seedlings (cm)
