Interrelationships of seed reserve utilization components in desi cotton (Gossypium arboreum)

Published on

Seedling growth is considered as a product of two
components, namely, amount of seed reserve mobilized
or seed reserve depleted (SRD) and conversion
efficiency of mobilized seed reserve to seedling tissue
or seed reserve utilization efficiency (mg seedling dry
weight /mg seed reserve depleted). Studies on genetic
variation and relationships among seed reserve and
other standard seedling vigor traits such as seedling
dry weight, rate/speed of germination, germination
uniformity etc. in a few major crops [1, 2] indicated that
utilization efficiency of seed reserve is a trait
independent of the standard seedling vigour traits.
Among the seed reserve parameters, total reserve
depletion as well as reserve depleted per gm seed have
been reported to decrease under moisture and salinity
stress but seed reserve utilization efficiency was
unaffected and the trait has been observed to be under
genetic control [3, 4].
