| 摘要: |
| 用甲壳素合成1#~7#甲壳素磷酸酯和甲壳素磷酸酯钾,分别测定1#~7#甲壳素磷酸酯的取代度,将甲壳素磷酸酯钾配成0.5 mg/L,2mg/L,5 mg/L,10 mg/L,20mg/L溶液,以蒸馏水为对照,进行番茄(Lycopersicon esculentum)种子的浸种发芽实验。浸种46.5~76.5 h;培养温度29.5℃;每只培养皿50粒,每种浓度重复3次。结果表明:6#、7#甲壳素磷酸酯钾对番茄种子不具有促进作用;而1#~5#甲壳素磷酸酯钾对番茄种子有不同程度的促进作用,其质量浓度以0.5 mg/L~20mg/L为最佳,其中1#、2#、3#、4#、5#甲壳素磷酸酯钾对番茄种子的发芽率分别比对照组增长6.7%、17.4%、16.7%、6.0%、16.0%。 |

| Abstract: |
| A series of Chitin Phosphate(1# to 7#) and Potassium Chitin Phosphate were synthesized from Chitin.The degrees of substitution of Chitin Phoshate 1# to 7# were determined. The Potassium Chitin Phosphate were prepared into solutions of 0.5 mg/L,2 mg/L,5 mg/L,10 mg/L and 20 mg/L Lycopersicon esculentum was appled in the trial,with 50 seeds in each petri dish,soaking time from 46.5 hours to 76.5 hours from species to species,thrice repeats for each concentration,the distilled water as control. The culture temperature was 29.5℃.Potassium Chitosan Phosphate 6# and 7# had no promotive effect to the Lycopersicon esculentum Potassium Chitosan Phosphate 1#,2#,3#,4# and 5# increased the germination rate of the seeds of the Lycopersicon esculentum by 6.7%,17.4%,16.7%,6.0%,16.0% respectively as compared with the control. The favorable concentration ranged from 0.5 mg/L to 20 mg/L. |
