Germination was essential in preparation for the subsequent few sorghum growth
cycles, but increasing the temperature was a major limiting factor. Temperature change effect,
provide information on appropriate sorghum cultivation techniques. Sorghum was the principal
cereal grown for food, feed, fodder, starch, fiber, dextrose syrup, biofuels, and bioenergy. This
study evaluated the effect of temperature variation on the viability and vigor of sorghum seeds.
This research applies Factorial Experiment in Completely Random Design, where the first factor
is three genotypes of sorghum Numbu, G1Marapi, and G3Marapi. The second factor was the
temperature variation of 18 °C–38 °C. Sorghum seeds were germinated for ten days and placed
in the growth chamber. The result showed that every 2 °C temperature increase gives a different
response to the germination of sorghum. The optimum temperature for sorghum seed germination
was 20 °C–32 °C, with good viability and vigor of > 80%. Root and shoot growth was optimal at
24 °C–28 °C, such as Numbu has a root length of 17.0 cm and shoot length of 18.3 cm at 24 °C,
but at 38 °C, no seed germination. However, the morphological mechanisms of sorghum response
were a basis for information to get tolerant genotype and maximize utilization of its local
germplasm to develop improved cultivars.
