Analyses on seed yield components of Setaria sphacetata cv.Narok
Setaria sphacelata cv.Narok is a key species for improved pasture development and seed production not only in different climatic zones in Yunnan but in warm temperate and subtropics in southern China because of its high productive performance since it was introduced from Australia in 1983. In Yunnan, heading and flowering of Narok occurred almost simultaneously, which makes seed more easily harvested.However, seed yield and germination rate of Narok were relatively lower, with only 45‐60 kg/hm2 of seed yield and 10％ of seed germination rate, restricting seriously the large‐scale commercial production of the species.Therefore, in the experiment, it was aimed to find out what would be the limiting factors by analyzing components related to seed yield and seed weight per thousand seed and seed yield of a single plant to provide practical technical solutions for improving the seed yield of the species.
