 Little is known about the breeding systems of tropical perennial ginger species. In this paper, we provide information about the breeding system of Alpinia kwangsiensis in Yunnan, Southwest China, specifically self-compatibility, mechanisms promoting outcrossing, and the visitation characteristics of pollinators. Populations of A. kwangsiensis have two(More)
We studied the floral and pollination biology of Amomum maximum. Our observations suggest that flexistyly is present in this species, and stigmatic behavior is similar as reported for Alpinia species. Two phenotypes occur in a ratio of 1:1 in natural populations. No fruit set occurred in the unpollinated bagged plants. Significant differences in seed set(More)
This experiment was conducted to determine the effect of variety and planting year on the nutritive values of corn fed to growing pigs. Four corn varieties examined in this experiment were planted in the same village located in Longhua County, Heibei Province, China, in 2012, 2013, and 2014, respectively. During each year, corn was hand-harvested in early(More)
