摘要
采用硅胶法对白皮松种子进行脱水处理,并将获得的各含水量的种子(7.27%、4.14%、3.19%和2.18%)在室温下贮藏4个月,以7.27%的种子低温贮藏为对照,通过测定咖啡酸、对-香豆酸、阿魏酸及水杨酸等含量,研究贮藏条件及回湿处理对白皮松种子酚酸类物质含量的影响。结果表明:(1)经脱水处理后,种子含水量与酚酸类抑制物质的含量成负相关关系;(2)与贮藏前相比,贮藏后各含水量种子的酚酸类抑制物质含量均有所升高,且咖啡酸和对-香豆酸含量与种子发芽率呈较高的相关性;(3)与未回湿种子相比,经逐级回湿处理后的各含水量种子酚酸类抑制物质的含量均下降,且阿魏酸和水杨酸与种子发芽率存在较高的相关性。
Different moisture content of Pinus bungeana seeds （7.27% ,4.14% ,3.19% and 2. 18% ） were desiccated by silica gel, after the desiccation, the seeds were separately stored in ambient temperature for 3 months, and the seeds that were stored in refrigerator temperature were as controls. The ability of germination, the activity of enzymatic and the content of malonaldehyde were determined after pre-humidification treatment. The results indicated that ： （ 1 ） After dewatering, the water content and seed phenolic inhibitory substances in the content of negative correlation ; （2） compared with the seeds before storage, the moisture content of seed phenolic inhibitory substances contents were increased, and caffeic acid with the-p-coumaric acid content on seed germination of a high correlation after storage ; （3） compared with the wet seed is not back, step by step back to the water content of seeds in the wet treatment phenolic acids inhibit substances has declined, and ferulic acid and salicylic acid on the germination rate has a higher correlation.
