高粱如果没有连续12小时的日照条件，就不会产生籽粒。美国科学家在得克萨斯州的研究中心着手探讨日照问题，目前已培育出不需12小时连续日照即可产籽的高粱新品种，费雷德·米勒是参与该高粱项目的科学家之一。他说，40年前得克萨斯的农民在1公顷土地上可望收获高粱籽550公斤 Sorghum does not produce seeds if it does not have 12 hours of sunshine. US scientists at the Texas research center set out to explore the issue of sunshine, and now has developed a new sorghum seed that does not require 12 hours of continuous inoculum, and Ferrell Miller is one of the scientists involved in the sorghum project. He said 40 years ago, Texas farmers expected to harvest 550 kilograms of sorghum seeds on 1 hectare of land
