Abstract
A decrease in the concentration of K ions below 3 mM in agar medium which also contained starch, casein hydrolysate, MgSO(4), and K(2)HPO(4) changed the growth pattern of Fusarium solani illuminated in diurnal 12-h light/12-h dark cycles from zonation to a feathery growth mode. Rubidium or cesium ions could replace potassium, but lithium, sodium, and the bivalent alkaline earth ions could not.
摘要
在含有淀粉、酪蛋白水解物、MgSO(4)和 K(2)HPO(4)的琼脂培养基中，K 离子浓度降低到 3mM 以下，会改变在昼夜 12 小时光照/12 小时黑暗循环中照明的茄病镰刀菌的生长模式，从带状生长变为羽毛状生长模式。铷或铯离子可以替代钾，但锂离子、钠离子和二价碱土金属离子则不能。
