six-seed
2.Thirty-six seed samples represented 34 population of 27 taxa of Schisandra are measured in three dimentions.
5.Methods:Six strychnos alkaloids isolated from the seed of Strychnos nux-vomica L . were studied for their antitumor activity in vitro by determining the inhibitory percentage against growth of human nasopharyngeal carcinoma cell line KB,human leukemia cell line HL-60,human gastric carcinoma cell line BGC and human hepatic carcinoma cell line BEL-7402.Results:It showed that strychnine inhibited growth of human carcinoma cell line KB,HL-60 and BGC;
9.The genetic correlations of six agronomic characters in some indica-japonica crosses were analyzed using mixed-linear model method.The results indicated that there existed correlations to a certain degree among the measured traits.The phenotypic correlations of plant height with filled grain or seed setting were significant.Panicle length with total grains or filled grain,total grains with filled grain or seed setting,and filled grain with seed setting were the same.For panicle length with plant height or seed setting,total grains with filled,and for filled grain with seed setting,genetic correlations were also significant.Further analysis,the result showed that genetic correlations between the measured traits were mainly due to domimant effects.In addition,additive correlations were significant for grain weight with panicle length or total grains or filled grain,and for total grains with filled grain.
10.comprising seed plants that produce an embryo with paired cotyledons and net-veined leaves; divided into six (not always well distinguished) subclasses (or superorders): Magnoliidae and Hamamelidae (considered primitive); Caryophyllidae (an early and distinctive offshoot); and three more or less advanced groups: Dilleniidae; Rosidae; Asteridae.
