What factors affect starch production in plant species?

Question

I need to compare the rate of starch production of two plant species.

What I'd like to know is what features of the leaves would increase/decrease the starch production when leaf disks are floated on glucose solution.

Thank you!

Answer 1

If you have leaf disks from different species in the same container of solution and in the same light, temp, etc., then you are just comparing the physical features of the leaves.

Leaf disks may photosynthesize faster if they are:
-- deeper green, indicating more concentrated chloroplasts
-- thicker, indicating more mesophyll cells
-- from plants that were already in bright light and well-watered because they would already have the process of photosynthesis underway. When we do photosynthesis rate experiments with leaves or with aquatic plants I usually put the plants under a grow light for at least 24 hours and seem to get better results.

Answer 3

so many factors which affects the production of starch , it may be 1) environmental and 2) plant factors.
1. light, wind, air, temperature ,water,and availability of food materials etc.
2.leaf surface, locality of plant present, speed of circulation of conduction etc.,
