在美国南部沿海大平原地区,珍珠粟是一种具有生产潜力的优质粒用作物,在有限的土壤水分条件下,珍珠粟的保苗似乎是优于高梁。比较珍珠粟和高梁种子对水分和温度不足时的反应,将有助于评价它们的相对适应性以及解释在田间条件下所观察到的反应。Smith 和 Hoveland(1986)用珍珠粟和高梁的单个栽培品种发现,当渗透压从0升到1.0毫巴时,两者的发芽率分别减少6%和 In the southern coastal plains of the United States, pearl millet is a high-quality grain crop with potential for production and seedling protection of pearl millet appears to be superior to sorghum under limited soil moisture conditions. A comparison of responses to pearl millet and sorghum seeds to moisture and temperature will help to assess their relative fitness and explain the observed responses under field conditions. Smith and Hoveland (1986) used pearl millet and sorghum single cultivars to find that when the osmotic pressure increased from 0 to 1.0 mbar, the germination rates of both were reduced by 6% and
