The results showed that both of the chlorophyll a and total chlorophyll contents decreased under the stress of neutral salt. The changes of the chlorophyll b was not obvious and a/b not consistent. The chlorophyll a and total chlorophyll of R. pseudoacacia appeared an increasing decliningincreasing trend under the stress of mixed salt. The chlorophyll a and total chlorophyll of F. velutina increased under the stress of mixed salt. The changes of the chlorophyll b was not obvious either and a/b appeared a rising trend.

结果表明在中性盐的胁迫下，刺槐和绒毛白蜡总叶绿素和叶绿素a的含量随盐胁迫程度的增加而降低，叶绿素b的变化较小，叶绿素a/b并不呈现单一的变化趋势；在碱性盐的胁迫下，刺槐总叶绿素和叶绿素a的含量随胁迫程度的增加呈现先升高后降低再升高的趋势，绒毛白蜡总叶绿素和叶绿素a的含量随胁迫程度的增加而上升，叶绿素b的变化较小，叶绿素a/b都呈现上升的趋势。

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。

There are experimental results as follows:(1) Eriophorum comosum Nees shows strong cold resistance in plasmalemma permeability research. The lethal temperature of Eriophorum comosum Nees is the lowest LT_(50 in comparison with another two plants and is lower than -11.5℃ in August 2005 and December 2005; Soluble protein content of each plant is rising before or after cold hardiness. By SDS-PAGE, Protein band is analysed. Band quantity of Eriophorum comosum Nees is the most and its band color is darkest.(2) Soluble sugar content of three plants after cold hardiness are higher than before cold hardiness, moreover soluble sugar content after cold hardiness shows a decline and there is a narrow range in Eriophorum comosum Nees; Free Proline accumulation is changed by cold stress, and cold resistance is relative to free Proline accumulation; chlorophyll content of both three plants, including chlorophyll a, chlorophyll b and chlorophyll a/b, show a decline tendency along with the descent of temperature. Cynodon dactylon is highly sensitive to cold stress.(3) The soil POD and urease activities' absolute value of Erioophorum comosum Nees and Pogonatherum panideumHack were more than that of Cynodon dactylon before or after low temperature stress, especially POD activities.

实验结果表明：(1)在膜透性的研究中，丛毛羊胡子草抗寒性最强，采用电导率法测得半致死温度LT_(50最低，丛毛羊胡子草抗寒锻炼前后半致死温度LT_(50均小于-11.5℃；在可溶性蛋白含量研究中，抗寒锻炼前后三种植物的可溶性蛋白含量均增加，同时采用SDS-PAGE法，通过对蛋白条带分析，以丛毛羊胡子草条带数最多且着色深；(2)在可溶性糖的研究中，三种植物经抗寒锻炼后叶片可溶性糖含量都比抗寒锻炼前高，且经过抗寒锻炼后三种植物可溶性糖均呈下降趋势，丛毛羊胡子草可溶性糖含量下降较小；从游离脯氨酸含量可知，低温的胁迫影响了植物叶片游离脯氨酸的含量变化，植物的抗寒性与游离脯氨酸有关；低温胁迫下三种植物叶绿素含量随着温度的下降，叶绿素含量、叶绿素a、叶绿素b和叶绿素a／b均呈下降趋势，狗牙根对低温胁迫最为敏感；(3)低温锻炼前后，丛毛羊胡子草和金发草的土壤过氧化物酶与脲酶活性的绝对值均大于狗牙根的，特别是过氧化物酶，说明丛毛羊胡子草和金发草的酶活性大于狗牙根的。
