Musk deer (Moschus moschiferus): Reinvestigation of main lipid components from preputial gland secretion.

abstract：:Sasa (Sasa cernua Makino) is a very serious weed pest. Its allelopathy was studied using lettuce, wheat, timothy, and green amaranth as testing species. Cultured in the rhizosphere soil ofSasa cernua, the seedlings were inhibited by 42-80% compared with the controls cultured in normal soil and vermiculite. The phenoli...
