摘要: :为探究贮藏温度对油茶种子品质的影响,揭示不同贮藏温度条件下种子活力指标(丙二醛含量和相对电导率)及内含物指标(可溶性糖、可溶性蛋白、脂肪和淀粉含量)的变化规律,以油茶种子为供试材料,将其自然风干至含水量为8.36%,随后分别贮藏于室温[(25±2)℃]、4 ℃、−20 ℃、−70 ℃条件下,分别于贮藏的0、60、120、180 d测定种子活力指标和内含物,采用模糊数学隶属函数值法进行综合评价。结果表明,随着贮藏时间的延长,4个温度条件下油茶种子的丙二醛含量和相对电导率总体上逐渐升高,可溶性糖、可溶性蛋白、淀粉含量整体呈下降趋势,脂肪含量出现不同程度的上下波动。与贮藏0 d相比,贮藏180 d,(25±2)℃贮藏条件下的种子活力指标(丙二醛含量和相对电导率)和种子内含物(可溶性糖、可溶性蛋白、淀粉含量)变化显著,其中,丙二醛含量和相对电导率分别增加199.38% 和104.09%,可溶性糖、可溶性蛋白和淀粉含量分别下降26.69%、47.95%和31.00%;−70 ℃贮藏条件下各指标变化不显著(可溶性蛋白含量除外),丙二醛含量和相对电导率分别增加38.15%和10.14%,可溶性糖、可溶性蛋白和淀粉含量分别下降16.78%、36.24%和6.40%。通过综合评价分析发现,4种贮藏温度下油茶种子品质排序为−70 ℃>−20 ℃>4 ℃>(25±2)℃。综上,为期180 d的贮藏过程中,低温环境(−20、−70 ℃)更利于油茶种子品质的保持,而(25±2)℃下的贮藏效果最差。结合生产实践的成本,建议选择−20 ℃作为油茶种子贮藏温度。

Abstract: To investigate the effects of storage temperature on the quality of Camellia oleifera seeds and reveal the variation patterns of seed vigor indices(malondialdehyde content and relative conductivity)and internal constituent indexes(soluble sugar content,soluble protein content,fat content,and starch content) under different storage temperature conditions,Camellia oleifera seeds were used as test materials.The seeds were naturally air‐dried to a moisture content of 8.36% and then stored at room temperature[(25±2)℃],4℃,−20℃,−70℃,respectively. Seed vigor index and inclusion index were determined at 0,60,120,180 days of storage.The fuzzy mathematics membership function value method was employed for comprehensive evaluation.The results showed that with the extension of storage time,the malondialdehyde content and relative conductivity of Camellia oleifera seeds generally increased gradually under all four temperature conditions,while the contents of soluble sugar,soluble protein and starch showed an overall decreasing trend,and the fat content fluctuated to varying degrees.Compared with 0 day of storage,at 180 days,the seed vigor indexes(malondialdehyde content and relative conductivity)and inclusion indexes(soluble sugar,soluble protein and starch content)were significantly different under the storage condition of(25±2)℃ .Among them,the malondialdehyde content and relative conductivity increased by 199.38% and 104.09%,respectively,while the contents of soluble sugar,soluble protein,and starch decreased by 26.69%,47.95% and 31.00%,respectively.Under the storage condition of −70℃,the changes of each index were not significant(except soluble protein content).The malondialdehyde content and relative conductivity increased by 38.15% and 10.14%,respectively,while the soluble sugar,soluble protein and starch content decreased by 16.78%,36.24% and 6.40%,respectively.Through comprehensive evaluation and analysis,it was found that the quality of Camellia oleifera seeds under four storage temperatures was ranked as follows:−70 ℃>−20 ℃>4 ℃>(25±2)℃.In summary,the low temperature environment(−20 ℃,−70 ℃)was more conducive to maintaining the quality of Camellia oleifera seeds during 180 days of storage,while the storage effect at(25±2)℃ was the worst. Combined with the cost of production practice,it is recommended to select −20 ℃ as the storage temperature of Camellia oleifera seeds.
