Investigating tree and fruit growth through functional-structural modelling: implications of carbon autonomy at different scales.

abstract：BACKGROUND AND AIMS:Jatropha curcas (jatropha) is an oil crop cultivated in (sub)tropical regions around the world, and holds great promise as a renewable energy source. However, efforts to fully commercialize jatropha are currently hampered by the lack of genetic diversity in the extant breeding germplasm, and by the ...
