Fruit growth and photosynthesis are differentially affected by local variation in source/sink relations

open access: yes, 2018
Tree crop load affects carbon acquisition as well as processes like floral induction or fruit growth. Nevertheless little is known about the impact of local variations of source / sink relationships on these processes variability ...

Cycas micronesica Stem Carbohydrates Decline Following Leaf and Male Cone Growth Events

open access: yesPlants, 2020
The growth of synchronized leaf flushes or male cones on Cycas trees is an ephemeral event, and non-structural carbohydrates (NSCs) are likely deployed from stem and root storage tissues to support their construction. The relationships among various stem
