摘要

在一系列培养实验中,根据十二个温度(12.5 - 40 ºC)测定了两个水稻品种(即 Bario Sederhana 和 Biris)的发芽率。根据 "断棒 "线性模型估算了发芽的中心温度和热时间。两个品系的 Tb 均为 10 ºC,Topt 在 32 - 33 ºC 之间,Tmax 为 43 ºC。在次理想温度下,Bario Sederhana 的发芽热时间为 62 ºCd,Biris 为 53 ºCd。在超理想温度范围内(Topt 至 Tmax),两个品种的种子萌发都需要 27-29 ºCd。Bario Sederhana 在 30 ºC 时的最终萌发率最高为 93%,而 Biris 在 27.5 ºC 时的萌发率为 100%。

Cardinal Temperatures and Thermal Time for Germination of Sarawak Traditional Rice
Germination of two rice landraces, namely Bario Sederhana and Biris, was determined from twelve temperatures (12.5 – 40 ºC) in a series of incubation experiments. The cardinal temperatures and thermal time for germination were estimated from a ‘broken-stick’ linear model. Both landraces had a Tb of 10 ºC, Topt between 32 – 33 ºC, and Tmax of 43 ºC. At the sub-optimal temperatures, the thermal time for germination was 62 ºCd for Bario Sederhana and 53 ºCd for Biris. Within the supra-optimal range (Topt to Tmax), both landraces required 27-29 ºCd for seed germination. The maximum final germination for Bario Sederhana was 93% at 30 ºC while Biris had 100% seeds population germinated at 27.5 ºC.
