In the bolting time and blooming time, B deficiency mainly influenced on the growth of the propagative organ of rapeseed ( Brassica Napus L.), the agronomic character was similar to the seedlings, and the B concentration range of the rapeseed varieties which responded to the B scarce was 0.005 mg/L to 0.25 mg/L.
苔期和花期,缺硼主要影响甘蓝型油菜繁殖器官的形成和发育,营养生长农艺性状的变化规律与苗期相似,品种间对缺硼反应差异最大的硼浓度范围为0.005 mg/L—0.25 mg/L。

In the seedlings time, the content of chlorophyll decreased by the deficiency of B, but the content of chlorophyll in the high efficiency cultivar decreased slowly than that of the low efficiency cultivar. This suggested that the leaves of the high efficiency cultivar can capture more light energy and the photosynthetic rate of the high efficiency cultivar decreased slowly. In the bolting time and blooming time, after two weeks of B deficiency treatment, the content of chlorophyll in the top leaves of the high efficiency cultivar decreased, and in the late time, the content of chlorophyll decreased slowly. But, the content of chlorophyll in the bellow leaves of the two cultivars had little changes. The reason may be that B in the high efficiency cultivar distributed to the propagative organ in the late growth, and the leaves were short of B.
苗期,缺硼导致甘蓝型油菜色素含量降低,且高效品种色素含量下降的幅度小于低效品种,表明营养生长阶段,同等程度的缺硼条件下,高效品种叶片对光能的收集能力以及光合速率下降的程度相对较小;苔期和花期,在两周的缺硼处理后,高效品种上部叶色素含量依然呈下降趋势,但随着生育期的推移,其下降幅度减小;而高效品种下部叶和低效品种叶片含量变化不大,可能是甘蓝型油菜进入生殖生长阶段后,高效品种将硼更多地分配到繁殖器官,而其叶片却承受了相对较大的缺硼胁迫。

Therefore, we selected common species of Ranunculaceae. comparative primordial plants in Alpine Meadow at Eastern QinghaiTibetan Plateau, and studied the reproductive strategies, such as reproductive allocation, especially sex allocation, to understand how the plants adapt the environmental conditions. The results showed:(1) At higher altitude, the self-incompatible plant, such as Trollius ranunculoides tended to become limited by pollination rather than by nutrient availability, while the self-compatible plants, such as Anemone rivularis and A. obtusiloba seemed not to be limited by pollen availability, which suggested that ability of self pollination for alpine plants may be a mechanism of reproductive assurance.(2) Influences induced by high altitude on the reproduction of these species occurred on different reproductive characters, which suggest species-specific adaptive strategies. The influences are dependent on plant size to some extent.
因此,我们选择在青藏高原东部的高寒草甸,以比较原始的植物类群—毛茛科植物为研究对象,选择一些常见种探讨其繁殖对策,如繁殖分配和性分配问题,试图揭示这些植物如何适应环境条件,最后的结果表明: 1高寒草甸高海拔区,自交植物(如小花草玉梅A.rivularis和钝裂银莲花A.obtusiloba)的繁殖不受花粉限制,而完全异交植物(毛茛状金莲花T.ranunculoides)的繁殖受花粉限制,表明高海拔地区植物的白花授粉能力可能是一种繁殖保障机制,能够避免恶劣环境对植物有性繁殖的不利影响; 2海拔高度对植物的影响因种而异,不同的物种受影响的繁殖性状不同,即使同属亲缘种间也存在差异,表明不同物种对相似环境压力的适应对策不同;而且,海拔高度对植物的影响在一定程度上依赖于植物个体大小,说明植物通过调整其个体大小与繁殖性状的关系来适应环境梯度的变化; 3植物花期和果期的繁殖分配并不完全随海拔升高而减小(只有小花草玉梅的果期RA随海拔升高而减小30%),与Iwasa和Cohen的预测不完全一致(他们认为繁殖分配随生长季缩短而减小)。
