辣椒种苗质量分级与壮苗指数构建
Quality grading of pepper seedlings and construction of seedling index
,
为综合且精确评价辣椒种苗质量,利用K-均值聚类法和综合评价法,对50 d苗龄的‘早熟红线椒’和‘加长六号’这2个品种的辣椒苗进行研究。结果表明:‘早熟红线椒’和‘加长六号’2个品种辣椒幼苗综合评价指数范围在0.333~0.996;利用主成分分析将11项指标分成2类主成分,累计贡献率为75.8%。将综合评价指数和壮苗指数进行相关性分析,筛选出4个相关性较高的壮苗指数模型:“地下部干重×散坨率×全株干质量”、“地下部鲜重×散坨率×全株干质量”、“全株鲜重×散坨率×全株干质量”和“相对叶绿素含量(SPAD)×散坨率×全株干质量”,相关性分别为0.673、0.690、0.657和0.701;最优壮苗指数模型为“地下部鲜重×散坨率×全株干质量”。根据筛选出的壮苗指数模型得到:综合评价指数≥0.813,壮苗指数≥1.255属于优质苗(Ⅰ级);综合评价指数范围在0.507~0.813,壮苗指数范围在0.102~0.682属于合格苗(Ⅱ级);综合评价指数≤0.507,壮苗指数≤0.102属于弱苗(Ⅲ级)。本研究可为辣椒的工厂化育苗、机械化作业提供优质种苗评价体系和种苗分级依据。
To comprehensively and accurately evaluate the quality of pepper seedlings, the K-means clustering method and comprehensive evaluation method were used to study the 50 day old pepper seedlings of two caltivars, ‘Early Mature Red Line Pepper’ and ‘Jia chang No.6’. The results indicated that: The comprehensive evaluate index of both ‘Early Mature Red Line Pepper’ and ‘Jia chang No. 6’ ranges from 0.333 to 0.996; The principal component analysis divided 11 indicators employed in this study into 2 types of principal components, with a cumulative contribution rate of 75.8%. Correlation analysis was conducted between the comprehensive evaluation index and the strong seedling index, and four models with high correlation were selected for the seedling index, which were ‘Dry weight of underground part×Scattered lump rate×Dry weight of whole plant’, ‘Fresh weight of underground part×Scattered lump rate×Dry weight of whole plant’, ‘Fresh weight of whole plant×Scattered lump rate×Dry weight of whole plant’, ‘SPAD×Scattered lump rate×Dry weight of whole plant’, and the correlations were 0.673, 0.690, 0.657 and 0.701, respectively. In conclusion, the optimal seedling strength index model is “Fresh weight of underground part×Scattered lump rate×Dry weight of whole plant”. Based on the selected robust seedling index model, it was concluded that: The comprehensive evaluation index≥0.813 and the strong seedling index≥1.255 belongs to high-quality seedlings (Grade Ⅰ); The comprehensive evaluation index range is 0.507-0.813, and the strong seedling index range is 0.102-0.682, which belongs to qualified seedlings (Grade II); The comprehensive evaluation index≤0.507 and the strong seedling index≤0.102 belongs to weak seedlings (Grade Ⅲ). In a word, this study provides a high-quality seedling evaluation system and a basis for seedling grading for industrial seedling and mechanized operations of fruity vegetables or other vegetables.
