无论怎样，这需要版材在平放时相当的平整，但由于成像过程采用直接接触曝光方式，整个过程可以接受各种类型版材表面不同平整度的变化，而这些表面的平整度变化是由生产传统版材时对铝基表面处理而造成的。

This conclusion is based on three groups of experiments with detached root tips of wheat seedlings: By following the time course changes of NO synthase , superoxide synthase and ABA accumulation under dehydration stress, we found that ABA accumulation was preceeded by the changes of NOS and superoxide synthase. ABA accumulation induced by dehydtrion stress and osmotic stress can be blocked by NO scanvegers and NOS inhibitors, while only dehydration stress-induced ABA accumulation can be blocked by ROS scanvegers. Exogenous applied NO or ROS induced ABA accumulation in root tips of wheat seedlings, and synergistic effects were found between NO and NO. The in planta expereiments also proved that ROS and NO are involved in water stress-induced ABA accumulation.Ⅱ.

证据主要来自以离体根尖为材料的实验：(1)通过检测干旱胁迫下小麦根尖NOS活性、O〓合成酶活性和ABA积累的时间变化进程，发现ABA积累滞后于ROS和NO的变化；(2)抑制剂实验表明，NO清除剂和NOS抑制剂可以抑制自然干旱胁迫及渗透胁迫诱导的小麦根尖ABA积累，ROS清除剂抑制自然干旱胁迫诱导的ABA积累而不抑制渗透胁迫诱导的小麦根尖ABA积累；(3)在非胁迫条件下施加外源的ROS或NO可以诱导小麦根尖积累ABA，ROS和NO之间具有协同作用。
