【题目】( 2015四川卷)植物侧芽的生长受生长素(IAA)及其他物质的共同影响。有人以豌豆完整植株为对照进行了以下实验:
实验一:分组进行去除顶芽、去顶并在切口涂抹IAA处理后,定时测定侧芽长度,见下左图;
实验二:用14CO2饲喂叶片,测定去顶8h时侧芽附近14C放射性强度和IAA含量,见下右图。
(1)IAA是植物细胞之间传递______________的分子,顶芽合成的IAA通过_______方式向下运输。
(2)实验一中,去顶32 h时Ⅲ组侧芽长度明显小于Ⅱ组,其原因____________________________。
(3)实验二中,14CO2进入叶绿体后,首先能检测到含14C的有机物是_______,该物质被还原成糖类需要光反应提供_____________________。a、b两组侧芽附近14C信号强度差异明显,说明去顶后往侧芽分配的光合产物_____________________。
(4)综合两个实验的数据推测,去顶8h时Ⅰ组和Ⅲ组侧芽附近的IAA浓度关系为:Ⅰ组_______(大于/小于/等于)Ⅲ组;去顶8h时Ⅱ组侧芽长度明显大于Ⅰ组,请对些结果提出合理的假设:____________________________。
