在对块茎生长动态进行研究的许多实验工作中是拿整个一株做样品的,整个一株的样品要进行整个生长期的考察。这个方法曾成功地阐明了有关植物的生长和发育对块茎总物质累积过程起有什麽样的影响的许多问题。但拿整个一株做样品的方法去对单个块茎生长过程进行研究时就并不中用,因为在采集样品时整个一株植物却被摧毁掉了。我们为了要对马铃薯块茎生长的昼夜周期性进行研究,特设计了一种能在田野条件下使用但不会损伤植株而
In many experimental work on the dynamics of tuberous growth, a whole sample is taken, and the whole sample is examined for the whole growth period. This method has successfully elucidated many of the problems associated with the effects of plant growth and development on the accumulation of total tubers. But taking a whole sample as a way to study individual tuber growth is not useful because the entire plant was destroyed while the sample was being collected. In order to study the diurnal cycle of potato tuber growth, we designed a plant that can be used under field conditions without damaging the plant
