【題目】( 2015四川卷)植物側芽的生長受生長素(IAA)及其他物質的共同影響。有人以豌豆完整植株為對照進行了以下實驗:
實驗一:分組進行去除頂芽、去頂并在切口涂抹IAA處理后,定時測定側芽長度,見下左圖;
實驗二:用14CO2飼喂葉片,測定去頂8h時側芽附近14C放射性強度和IAA含量,見下右圖。
(1)IAA是植物細胞之間傳遞______________的分子,頂芽合成的IAA通過_______方式向下運輸。
(2)實驗一中,去頂32 h時Ⅲ組側芽長度明顯小于Ⅱ組,其原因____________________________。
(3)實驗二中,14CO2進入葉綠體后,首先能檢測到含14C的有機物是_______,該物質被還原成糖類需要光反應提供_____________________。a、b兩組側芽附近14C信號強度差異明顯,說明去頂后往側芽分配的光合產(chǎn)物_____________________。
(4)綜合兩個實驗的數(shù)據(jù)推測,去頂8h時Ⅰ組和Ⅲ組側芽附近的IAA濃度關系為:Ⅰ組_______(大于/小于/等于)Ⅲ組;去頂8h時Ⅱ組側芽長度明顯大于Ⅰ組,請對些結果提出合理的假設:____________________________。
