植物生命活动调节的基本形式是激素调节，下面是有关植物激素的知识及实验研究，请根据有关信息分别回答下列问题。植物激素对植物的生长发育具有显著调节作用，植物的生长发育是由多种激素相互协调、共同调节的，下表是植物不同部位各种激素的相对浓度，请分析后回答：
（1)植物体内除了上述四种激素外，还有_______，其作用是促进植物果实的成熟。（2)比较茎尖和伸长茎中各种激素的含量，同时从细胞学基础来分析植物的生长，说明生长素和赤霉素主要通过促进___\__而促进生长，细胞分裂素主要通过促进________而促进生长。（3)分析上表可知，成熟叶中含有较多的脱落酸而不含细胞分裂素，科学家通过进一步分析研究得知：脱落酸可抑制核酸、蛋白质的合成并提高核酸酶的活性，从而促进核酸的降解，使叶片衰老，而细胞分裂素则抑制叶绿素、核酸和蛋白质的降解，抑制叶片衰老。所以在生产中可利用细胞分裂素作保鲜剂。请你设计—个实验证明细胞分裂素有延缓叶片衰老的作用。①实验原理：叶绿素逐渐丧失是叶片衰老最明显的特点，离体叶片很快就会出现衰老的特点，因此可通过__________来证明。②实验步骤：第一步：选取________叶片若干片，平均分为两组，分别标记为甲、乙；第二步：在甲组叶片的局部位置涂上一定浓度的细胞分裂素，乙组叶片_______；第三步：________。③实验结果预测及结论：______\_，_________。
