Shade limited root mass and carbohydrate reserves of the federally endangered Beach Clustervine Jacquemontia reclinata grown in containers

Abstract:

Anecdotal evidence suggested that germination and seedling growth of the federally endangered beach clustervine (Jacquemontia reclinata [Convolvulaceae]) were best in the shade, but mature plants usually occur in coastal strand areas that are open or have low vegetation. We conducted an experiment using potted seedlings grown without shade, or under low, moderate, or heavy shade enclosures.ÿShade did not affect shoot growth, or leaf or stem dry mass.ÿPlants subjected to all levels of shade, however, had 40% to 70% less root dry mass and about 50% lower root-to-shoot ratios than non-shaded plants.ÿMoreover, the roots of non-shaded plants had 2 to 4 times more soluble sugars and starch than plants grown in shade.ÿThese findings suggest that when water and nutrition are not limiting, J. reclinataseedlings are best grown without shade.
