不同种源木姜叶柯种子生物学性状变异及质量特征研究 作者： 杨志玲 1,2 谭梓峰 1,2 王依清 3,4 作者单位： 1. （1）中国林业科学研究院亚热带林业研究所，杭州 311400；（2）浙江省林木育种技术研究重点实验室， 杭州 311400；（3）湖南翱康生物科技有限公司，湖南 溆浦 419300；湖南瑶茶工程技术研究中心，湖 南 溆浦 419300 提交时间： 2021-04-29 摘要: 为探讨不同种源木姜叶柯种子生物学性状变异规律和质量特征，该文以 8 个省份 10 个种源为 对象，测定了种子 4 个生物学性状、4 个营养成分及 3 个质量性状数值，开展了 11 个种子特征参数 的相关性及聚类分析。结果表明：（1）种子单粒重、种子长、种子数/种序、种序长均值依次为 1.82 g、14.57 mm、16.43 个、11.78 cm，不同种源种子 4 个生物学性状变异均达到极显著水平。（2）种 子蛋白质、脂肪、还原糖和淀粉均值分别为 4.75 g/100g、0.97 g/100 g、1.13 %、74.23 g/100 g，淀粉 在 4 个营养成分指标中差异最小。（3）种子百粒重、含水率和生活力均值依次为 172.92 g、44.05%、 53.00%，不同种源种子 3 个质量性状差异较大。（4）种子 4 个生物学性状与淀粉、蛋白质分别正向、 负向相关，种子长与脂肪及还原性总糖正相关。（5）种子生物学性状与生境因子相关性复杂，种序 长与无霜期极显著相关，相关系数达到 0.832，与海拔显著负相关，相关系数达到-0.698，随纬度递 增种子品质略变差。（6）种子聚类为第Ⅰ类短种序高营养成分型，第Ⅱ类长种序高生活力型，第Ⅲ 类种子繁多高淀粉型等 3 类，聚类不呈现地理效应。综上所述，不同种源种子生物学性状和质量变异 丰富，说明不同种源在子代分化已有遗传基础，种源筛选还需结合田间试验。 Abstract: In order to investigate variation of biological traits and quality characteristics in Lithocarpus litseifolius seeds, 4 biological traits ,4 nutrient content and 3 quality characteristics were measured from 10 provenances in 8 provinces. The correlation and cluster analysis of 11 seed characteristic parameters were carried out. The results were as follows: (1) The mean values of single seed weight, seed length, seed numbers per panicle and panicle length were 1.82 g, 14.57 mm, 16.43 ge and 11.78 cm respectively. Variation of four biological traits of seeds from different provenances reached very significant level. (2) The average values of protein, fat, reducing sugar and starch of seed were 4.75 g/100 g, 0.97 g/100 g, 1.13 %, 74.23 g/100 g respectively. Starch was the smallest difference among four nutrient indexes. (3) The mean values of a hundred seeds weight, rate of water content and viability were 172.92 g, 44.05 % and 53.00 % separately. Three quality characteristics of seeds from different provenances varied greatly. (4) Variation of four biological traits of seeds had positively or negatively correlated with starch and protein. Barely seed length had a positive correlation with fat and reducing total sugar. (5) The correlation between biological traits and habitat factors was very complex. Only panicle length had a positive significant correlation with frost-free-period, the correlation coefficient arrived at 0.832. In the mean time, panicle length had a negative correlation with altitude, the correlation coefficient reached -0.698.The quality of seed became slightly worse while latitude increasing. (6) Seed were classified into three groups based on clustering analysis. Group I was characterized by short panicle and high nutrient content. Group II was seized of long panicle and high viability. Group III had seeds numerous and high starch content. Seed clustering didn’t appear geographical effects.In a word, variation of biological traits and quality characteristics of seeds from different provenances were very rich, which indicated that there had a genetic basis from different provenances for progeny differentiation. It will be given a suggestion that provenance screening needs to be combined with field experiments. 木姜叶柯 生物学性状 质量特征 变异 相关性分析 聚类分析 分类： 生物学 >> 植物学 >> 应用植物学 引用： ChinaXiv:202105.00031 (或此版本 ChinaXiv:202105.00031V1 ) doi:10.12074/202105.00031 CSTR:32003.36.ChinaXiv.202105.00031.V1 推荐引用方式： 杨志玲,谭梓峰,王依清.(2021).不同种源木姜叶柯种子生物学性状变异及质量特征研究.广西植物.[ChinaXiv:202105.00031] 版本历史 [V1] 2021-04-29 12:31:38 ChinaXiv:202105.00031V1 下载全文

Utilizing content analysis method, the paper makes statistical analysis on the target literature from the year of publication and the subject area; then the paper puts its focus on the research theme analysis and hot topics in the past five years from two perspectives of interdisciplinary research, and the subject function of LIS and the objects.[Result/conclusion] Researches on evidence-based science in the field of LIS involve a number of subject areas including medicine, nursing and health care, policy science, information systems and education. The main research themes on evidence-based science in LIS are summarized into 10 categories in the end, of which "Services of LIS Institutions and Librarians' Professional Development" and "Evidence Sources and Its Access Methods or Technologies" are viewed as the core topics. China is relatively weak whether in terms of the breadth of subject areas and themes covered or the depth of research on each theme. 图书情报学 循证科学 内容分析法 期刊： 图书情报工作 分类： 图书馆学、情报学 >> 图书馆学 引用： ChinaXiv:202308.00522 (或此版本 ChinaXiv:202308.00522V1 ) doi:10.12074/202308.00522 CSTR:32003.36.ChinaXiv.202308.00522.V1 推荐引用方式： 卜玉敏,曲建升.(2023).图书情报学(LIS)领域的循证科学研究进展.图书情报工作.[ChinaXiv:202308.00522] 版本历史 [V1] 2023-08-27 01:09:04 ChinaXiv:202308.00522V1 下载全文
