(9分)许多实验研究生长素(IAA)对植物生长的影响模式,如用玉米胚芽鞘作为实验材料:
实验1:将切除的胚芽鞘尖端放置于琼脂块上(图1),移去尖端后,将琼脂切成体积相等的若干个方块,将方块放在除去尖端的胚芽鞘上,实验进行一定时间后,每个胚芽鞘弯曲的角度以图2的方法测量,并计算平均值。每次放在等面积、等体积琼脂块上的胚芽鞘尖端数量不同,这样重复上述过程。

 实验2:用含有不同浓度IAA的琼脂块代替胚芽鞘尖端进一步实验。上述两个实验的结果如图3和图4所示。

(1)绘图表示,如何将琼脂块放置于胚芽鞘上,才能得到图3的结果?
(2)解释实验2的结果:IAA从0μmol/L~1.3μmol/L过程中    ;1.3μmol/L~1.8μmol/L过程中         
(3)①比较实验1和实验2的结果有什么不同?             
   ②为什么会出现这种不同?                     。
(4)从本实验可知促进胚芽鞘生长的最适生长素浓度约为_______                    
图4中曲线上b点对应生长素浓度时胚芽鞘弯曲角度为17度,把琼脂块去掉后,胚芽鞘最终会如何生长?________
