为了解决消费者对新鲜刺梨和生产后刺梨的食用量确定,以及营养获得等问题,以新鲜刺梨及不同程度烘干后的刺梨为试验材料,采用数据对比的方法对刺梨果实的维生素C和SOD进行了研究。试验通过分光光度计法测定不同含水率下刺梨Vc含量和SOD活性,并选择苹果、猕猴桃等常见水果同时测定比较。结果表明：刺梨鲜果Vc含量在1900~2200 mg/（100 g·FW）之间,为苹果的46~53倍,为猕猴桃的14~17倍。当含水率降至60%,刺梨果实Vc含量损耗开始显著。刺梨果中有丰富的SOD,当含水率从75%至全干状态过程中,刺梨果实的SOD损失非常显著。试验结果为指导消费者合理食用提供参考。 相似文献

为研究不同产地刺梨中微量元素含量特点,采用电感耦合等离子体质谱法(ICP-MS)测定不同产地刺梨中11种微量元素的含量,并运用主成分分析和聚类分析对测定结果进行综合评价。结果表明,不同产地刺梨中微量元素含量顺序为FeMnSrBaZnCuTiCrVCoTl,刺梨各微量元素间具有较强的相关性。主成分分析表明,11种微量元素简化为4个主成分,累积方差贡献率为93.538%,可反映刺梨中微量元素的93.538%信息量,其特征微量元素为Fe,Sr,Ba和Cu。聚类分析将7个产地刺梨聚为4类,不同产地刺梨微量元素具有明显的差异性,可实现刺梨产地的初步判别。7个产地刺梨果实中,六盘水市、遵义市和黔南州微量元素综合得分较高、质量较好。 相似文献

贵州刺梨气候适宜性研究 总被引：1，自引：2，他引：1
为了找出影响刺梨产量和品质的主导气象因子,并划分贵州刺梨气候适宜性区域,笔者在贵州6个地州市设置20个试验观测样地,对气象实测资料、物候观测资料、刺梨果实品质资料、野生刺梨资源分布状况调查资料进行整理分析。结果表明：5—8月平均气温、7月平均气温、3—10月≥10℃活动积温、3—8月降水量是影响刺梨产量和品质的主导气象因子,刺梨单果均重和单果平均直径随着3—8月降水量的增加而增加,降水量过多或过低都不利于VC和SOD的合成;5—8月均温和3—10月≥10℃活动积温过高或过低,都不利于水溶性总糖和还原糖的合成,并通过0.05的显著性检验。根据刺梨分布区域的气候资料,对通过80%的保证率进行统计,进行刺梨气候适宜性指标建立和适宜性区划结果分析,区划结果为：在贵州省中部,毕节地区的大部分县市,西南部的部分地区,遵义市北部的部分县份为刺梨最适生区;在贵州省的西北部、西南部等边缘地区、黔东南部分地区为刺梨次适生区,其余地区为适生区。 相似文献

Diploid, tetraploid, and hexaploid plants occurred in foreign plant introductions of P. sp. affin. P. montanum from Turkey and Iran. Within-progeny variations in polyploid levels indicate that divergent races occurred as interspersed but natural populations. One to six B-chromosomes of varying sizes in addition to the normal chromosome complement were present in some plants. Their behaviours appeared essentially similar to those recorded for other species. Certain of the plants examined exhibited cytological features similar to those observed in known hybrids. These included prophase pycnosis, stickiness, split metaphase I plates, unoriented chromosomes at M-1, and low levels of pollen stainability. These features were absent in microsporocytes of other plants. Low open-pollination seed set characterized all plants examined. This may be due to hybridity or possibly to response to ecological conditions of the new environment.Results of co-operative work of the Crops Research Division, A.R.S., U.S. Department of Agriculture, and the Wisconsin Agricultural Experiment Station, Madison, Wisconsin.Former Graduate Student, Department of Agronomy, Wisconsin Agricultural Experiment Station, and Geneticist, Crops Research Division, Agricultural Research Service, U.S. Department of Agriculture. 相似文献

A widely-held belief is that stricter environmental regulations stifle economic growth. To determine empirically the effect of environmental conditions and policies on state-level per capita income growth, a Barro-type economic growth model was estimated for the years 1982 to 1991, which correspond to two consecutive troughs in the business cycle. States with better environmental conditions had significantly higher income growth rates during this period. At the same time, stricter environmental policies did not significantly depress income growth. Data used include recently developed, consistent measures of environmental policy and quality for individual states, as well as data from the 1980 U.S. Census and Bureau of Economic Analysis. 相似文献
