Summary
1. The yellowing of the leaf cultured on sugar solutions was found to be better than that in controls.
2. This was found to be due to the higher carbohydrate content of the sugar-fed leaves, as compared to controls.
3. After briefly reviewing the literature on yellowing, a hypothesis on the role of carbohydrates has been suggested.
4. The water content of the leaves was found to play a part too and this was explained as due to the mobility of carbohydrates.
5. The better grading analysis of sugar-fed leaves as compared to controls in a semi-large scale experiment was in line with the yellowing behaviour of the sugar-fed leaves.
