| Abstract: | Sorghum [Sorghum bicolor (L.) Moench. cv GP‐10] root tips (1‐cm) were exposed to 45Ca2+ for 1 hr. Root tips were washed in 0.01M EDTA for 5, 10, 15, 30, and 60 min. Calcium (45Ca2+) remaining in the roots decreased on a T1/2 = 12–13 minutes scale, which represents Ca2+‐ATPase activity in the GP‐10 root tips (1‐cm). |
