Abstract
DIFFERENT vegetative characters are taken into consideration for describing the individual groups and varieties of rice (Oryza sativa L.), but little importance has so far been attached to the behaviour of the plants with regard to the ratio of the length of leaf sheath to that of leaf blade. With the view of studying the sequences of the ratios in all the successive mature leaves and their relationship with certain important developmental stages, the present investigation was undertaken with three rice varieties, namely, F.R.13A (aman), Satika (aus) and C.B.I (boro).
