1.研究发现盆养植物的根很快扩展到盆壁

2.从小盆换成大盆,植物的大小可以增加大约40%

To understand the pot size effect, the scientists looked at various aspects of the plants' growth. They found that the plants in smaller pots grew more slowly because of a decreased rate of photosynthesis. But, looking for causes for the decrease, the scientists ruled out limitations in water and nutrients and did not find any differences in the thickness of the leaves for plants in smaller pots. It is therefore unlikely that the plants use water and nutrient levels to sense the pot size, supporting the possibility that sensing happens another way, such as by the roots.

结论: 用多大的盆来养试验植物才能避免盆对植物试验的影响? 值得研究.

用盆养植物做实验的童鞋门注意啦!!
