摘要/Abstract

摘要： 为了探讨起源地生态地理因素对野生燕麦种子形态、营养品质的影响，以来自以色列不同地区的6个群体共60个生态型野生燕麦为材料，研究其种子千粒质量、面积、周长、长/宽、长、宽、直径、圆度8个形态指标及总类黄酮、植酸、总酚、无机磷、氨基含量5个营养品质指标，并分析其与起源地生态地理因素间的关系。结果表明，种子长/宽、长、圆度在6个群体之间均无显著差异，其余形态指标在群体间差异明显，且在Tabigha、Nahef间差异显著；Tabigha群体千粒质量、面积、周长、长、宽、直径均最大，Nahef群体均最小。6个野生燕麦群体间籽粒总酚、植酸、无机磷、氨基含量均无显著差异，仅总类黄酮含量在Nahef和Tabigha间差异显著。斯皮尔曼秩相关性分析结果表明，千粒质量与年平均温度、8月平均温度、1月平均温度、季节温差均呈极显著或显著正相关，与年降雨量、年降雨天数分别呈显著、极显著负相关；面积、长、周长、直径与年平均温度、8月平均温度、1月平均温度均呈显著或极显著正相关，面积、直径与年降雨天数分别呈极显著、显著负相关；长/宽与年平均温度、8月平均温度均呈显著负相关；宽与年平均温度、8月平均温度、1月平均温度、季节温差、昼夜温差均呈极显著或显著正相关，与海拔、年降雨量、年降雨天数均呈极显著或显著负相关；圆度仅与8月平均温度呈显著正相关，与其余起源地生态地理因素间均不存在显著相关性。总类黄酮含量与年平均温度、8月平均温度、1月平均温度、季节温差均呈极显著或显著负相关，与年降雨天数、年平均湿度均呈显著正相关；植酸含量仅与经度呈显著负相关；无机磷含量与经度、纬度均呈显著负相关。

Abstract: In order to explore the effects of ecogeographic factors on the seed morphological characters and nutritional quality of wild oat,60 ecotypes of 6 wild oat groups from different regions of Israel were used as materials,the 1 000-grain weight,area,circumference,length/width,length,width,diameter,roundness and contents of total flavonoids,phytic acid,total phenol,inorganic phosphorus,amino were studied,and their correlation with the ecogeographic factors of origin area was analyzed.The results showed that there was no significant difference in seed length/width,length and roundness among the six populations,the other morphological characters were different among the six populations,and the differ ence was significant between Tabigha and Nahef populations,The Tabigha population had the highest 1 000-grain weight,area,circumference,length,width and diameter,and the Nahef population had the smallest.There were no significant differences in total phenolic,phytic acid,inorganic phosphorus and amino contents among the six wild oat populations,and only total flavonoid content was significantly differ ent between Tabigha and Nahef populations.The Spearman rank correlation analysis result showed that the 1 000-grain weight was significantly or extremely significantly positively correlated with annual average temperature，average temperature in August,average temperature in January and the seasonal temperature difference,and significantly,extremely significantly negatively correlated with annual rainfall,annual rain fall days,respectively.Area,length,circumference and diameter were significantly or extremely significant ly positively correlated with annual average temperature,average temperature in August and average tem perature in January.Area and diameter were extremely significantly,significantly negatively correlated with annual rainfall days,respectively.Length/width was significantly negatively correlated with annual average temperature and average temperature in August.Width was significantly or extremely significantly positively correlated with annual average temperature，average temperature in August，average temperature in January,seasonal temperature difference and day-night temperature difference,and significantly or ex tremely significantly negatively correlated with altitude,annual rainfall and annual rainfall days.ound ness was only significantly positively correlated with average temperature in August，and there was no sig nificant correlation with the other ecogeographic factors of origin area.The total flavonoid content was sig nificantly or extremely significantly negatively correlated with annual average temperature，average temper ature in August，average temperature in January and seasonal temperature difference,and significantly positively correlated with annual rainfall days and annual average humidity.Phytic acid content was only significantly negatively correlated with longitude.
