下列有关植物激素调节的叙述,不正确的是
[ ]
A.使用一定浓度的生长素处理扦插枝条,能提高插条的成活率B.使用一定浓度的赤霉素处理芹菜幼苗,能提高芹菜的产量C.使用一定浓度的脱落酸处理浸泡过的小麦种子,能提高种子的萌发率D.使用一定浓度的乙烯利处理凤梨,能让凤梨提前上市
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:______\_,_________。
