The sporangiophores of Phycomyces do not exhibit phototropic responses when growth is arrested reversibly by cooling to 1 degrees C. Unilateral UV stimuli (254 nm) applied during cold periods are stored for at least 2 hr and produce tropic responses away from the light after warm-up. During the cold period dark adaptation proceeds at a rate which decreases with the temperature.
当通过冷却至1摄氏度使毛霉的孢子囊柄生长可逆地停止时，它们不会表现出向光性反应。在低温期间施加的单侧紫外线刺激（254纳米）会被储存至少2小时，并在升温后产生背光性反应。在低温期间，暗适应以随温度降低的速率进行。
