生长物质

The promotion of the growth of the stem is not due to the increment of the number of internodes, but is chiefly due to the elongation of their internodes.

茎部生长的促进作用，并不是由于节间数目的增加，主要是由于茎部各节间有不同程度的伸长，相应也增加了各节间干物质的积累。

The addition of malt extract and glutamine could inhibit non-embryonic calli, and make the culture be mainly composed of embryonic calli; change of the 2,4-D concentration in liquid culture medium could adjust the status of embryonic calli to the suitable developmental stage for protoplast isolation.

通过麦芽提取物和谷氨酰胺两种物质的添加，可以起到抑制非胚性愈伤生长的作用，使培养物主要以胚性愈伤为主；通过液体培养基2，4-D浓度的改变，可调节胚性愈伤处于合适的发育时期，便于原生质体的分离。

The results showed that the calorific values of the test plant species had no unified change pattern, which was possibly related to the partitioning ratio of calorific value in different plant organs and the timing when the reproductive period appeared. In general, spike had a higher calorific value than leaf and stem, and aquatic plants had obviously lower calorific value than mesophytes and wet mesophytes. Within a species, the change pattern of calorific value had certain relations to the phenophase, with approximately two lowest values and two highest values. Among the species, the differences in the calorific value were decided by the nature of the species themselves. Under the same habitat and climatic conditions, the species that contained more materials rich in energy could more easily accumulate calorific, and thus, more adaptable to grow under this environment.

结果表明：各物种的热值动态变化规律并不是统一的，这种变化可能与植物各器官热值的变化及生殖期出现的时间有关；各植物器官的热值普遍表现出穗的热值大于茎和叶；水生植物的热值明显小于中生性和湿中生性植物；种内热值变化随物候期变化有一定的规律，大约会出现2次低值、2次高值；种间热值差异是由于植物本身性质决定的，在相同生境和气候条件下，植物体中含能物质越多，就越易积聚热值，从而更适宜生长在此环境。

Also, the relationship between these growth elements and yield was investigated. The results were as follows: Fertilization obviously increased the number of tillings, so increased the number of stems and ears of winter wheat per hectare as well.
