34、(16分)某科研组对密闭大棚内番茄的光合作用与呼吸作用进行了研究。绘出了单株番茄光合作用强度与种植密度的关系图(甲)和M点对应情况下的大棚内一天中的CO2含量的变化图(乙)。用红外测量仪在恒温不同光照下测得右表数据(实际光合量用葡萄糖表示)和植株呼吸作用释放CO2为0.6umol/h。请回答:

 

(1)从以上研究可知,影响该植物光合作用的因素有__________________;番茄植株分别在图中N、B、F时,限制其光合作用强度的主要外界因素中,共同的因素是    

        

(2)在图乙中DE段时,植株叶肉细胞中产生[H]和ATP的场所是_______________,该段曲线形成的直接原因是_______________________。

(3)若给大棚中的番茄植株一定量的14CO2,则在适宜光照下,14C首先会出现在番茄植株叶片的________________细胞中的___________化合物中。

(4)当光照强度为1klx时,番茄植株的实际光合量都为0.1umol/h,这与图乙中__________点对应的光合作用情况类似。

(5)在一定浓度范围内植物对CO2的转换率(单位时间内植物吸收的CO2与外界CO2浓度的比)为定值。光照强度为2klx实际光合量为0.27umol/h时,植物对CO2的转换率为___________。

33、(6分)为了验证“植物主茎顶芽产生的生长素能够抑制侧芽生长”,某同学进行了以下实验: ①选取健壮、生长状态一致的幼小植株,分为甲、乙、丙、丁4组,甲组植株不做任何处理,其他三组植株均切除顶芽。然后乙组植株切口不做处理;丙组植株切口处放置不含生长素的琼脂块;丁组植株切口处放置含有适宜浓度生长素的琼脂块。

②将上述4组植株置于相同的适宜条件下培养。回答下列问题:

(1)各组植株侧芽的预期生长情况分别为: _____________________________________

___________。(2分)

(2)比较甲组与乙组的预期结果,能够说明______________________________。

32、(12分)为丰富植物育种的种质资源材料,经常利用钴60的γ射线辐射植物种子,筛选出不同性状的突变植株。请回答下列问题:

(1)钴60的γ辐射用于育种的方法属于       育种。

(2)从突变材料中选出抗盐新品种,利用该植株进行部分杂交试验:

① P:♀不抗盐 ×♂抗盐 → F1:不抗盐;    ② P:♀抗盐×♂不抗盐 → F1:抗盐。

由实验结果可知,抗盐性状属于       遗传。

(3)从突变植株中还获得了显性高蛋白植株(纯合子),为验证该性状是否由一对基因控制,

请参与实验设计并完善实验方案:

① 步骤1:选择                  杂交。

预期结果:                                   

② 步骤2:                                   

预期结果:                                   

③ 观察实验结果,进行统计分析:如果               相符,可证明该性状由一对基因控制。
