The experiment that aPplication of Put shows that Put can inhibit chlorophyll discomposing and lower POD activity; Lower concentration (about 5mmol/L) can decrease respiration rate; ethylene's synthesis result in prolonging the storage time; Higher concentration (about l0,20mmol/L) Put can activate the respiration in some degree and disadvantage to storage.

外源腐胺处理香蕉果实的实验表明，腐胺可以减缓叶绿素的降解，另外，低浓度的（5mmol/L左右）腐胺可以较好的抑制乙烯的生成和呼吸作用，延缓果实衰老，而高浓度（10、20mmol/L）则在一定程度上刺激了呼吸作用，对贮藏不利。

Field experiments were conducted to examine integrated inhibition of allelopathic rice (Huakangcao 78), bensulfuron methyl application and water management on weeds in paddy field, with the purposes of attempting to reduce the dosage of herbicide applied in rice field and exploring new ways of weed management in rice production. The results showed that allelopathic rice could inhibit the germination and growth of barnyardgrass Echinochloa crusgalli L.

In order to study the influence of nitric oxide and copper ion on marine algae growth,Skeletonema costatum and Gymnodinium sp.were incubated when adding different concentrations of NO and copper with different addition methods,and the preliminary functional mechanism was discussed.

为研究一氧化氮与金属铜对海洋微藻生长的影响，选用中肋骨条藻和裸甲藻(Gymnodinium sp。)进行了不同NO和Cu浓度、不同添加方式的室内培养实验，初步探讨了它们的作用机制。结果表明：一次性或每天两次加入不同浓度NO(10-5~10-10mol/L)，对微藻的生长表现出不同程度的促进或抑制作用，呈&两面性&。

To further investigate their roles in cell proliferation apoptosis and differentiation, three human leukemia cell lines (K562, U937 and HL60) exposed to various concentration of hexamethylene bisacetamide, a potent inducer of differentiation of transformed cells both in vivo and in vitro, were used as an in vitro model for the study of cell proliferation, differentiation and apoptosis.

为了进一步研究cyclin A和p21在白血病细胞增殖，分化，凋亡中的作用，我们用在体内，外均有抗肿瘤作用的药物六亚甲基二乙酰胺在体外抑制白血病细胞株K562，U937和HL60增殖，诱导其分化，成功地建立了与药物干预浓度呈剂量-效应关系的，具有不同增殖，分化，凋亡状况的实验细胞模型。

In mice, Zanthoxylum bungeanum and lower dosage (500,1000mg/kg) of Illicium verum , Cinnamomum japonicum do not damage the bone marrow cell chromosome. But in high dosage, the Zb can inhibit the bone marrow cellproliferation, and the Iv and Cj can at different degree influence the stability of bone marrow cell chromosome.

花椒组和低剂量的八角、桂皮对小鼠骨髓细胞染色体没有损伤作用，高剂量花椒对小鼠骨髓细胞的增殖有一定抑制作用，高剂量八角、桂皮对小鼠骨髓细胞染色体的稳定性有不同程度的影响。

The concentrations of TN in all the treatments decreased to lower levels at the middle and latter periods of the experiment, and those of TP also decreased at larger extents. Compared with the control, DDT at 200μg·L-1 inhibited growth and reproduction of the dominant macrophyte Lemna minor, but the reverse was found for DDT at other concentrations.
