Studies of growth & metabolism of a barley mutant lacking chlorophyll b

Abstract

Comparison of the mutant barley lacking chlorophyll b with a normal barley shows that the respiratory and photosynthetic rates of detached leaves and whole plants were not significantly different when compared on the basis of chlorophyll a content, fresh weight, or dry weight. Normal and mutant plants exhibit the same growth rates until the endosperm of the seed is depleted. Differences in growth and certain sugars were observed after depletion of the endosperm.
