Influence of size grading on physiological parameters in Tephrosia (Tephrosia purpurea) MDU (KO)-1

Journal Title: Journal of Applied and Natural Science - Year 2017, Vol 9, Issue 1

Abstract

Seed grading is an important practice for better crop establishment and to improve efficiency of planting ratio in field and also useful in separation of quality seed in a seed lot. The influence of seed size on physiological and biochemical seed quality characters were evaluated in Tephrosia seeds using seeds retained on 5.5/64″, 6/64″ and 7/64″ sieves along with control. The estimations revealed that larger size seeds retained on 7/64" sieves recorded the maximum recovery (64 %), 100 seed weight (2.0 g), speed of germination (14.1) germination ( 86 %), root length (8.5 cm), shoot length (11.0 cm), dry matter production (15.92 mg seedlings-10), vigour index (1677) and protein (10.56 %) compared to BSS 5.5 / 64'', BSS 6 / 64'' and ungraded seeds.
