摘要:

研究制定符合生产实际的蒜头果种苗质量分级标准,为蒜头果种苗繁育和规范化生产提供参考。在蒜头果主要产区云南省富宁县随机选取移栽前的20批次蒜头果种苗,测量鲜重、株高、叶片数、叶长、叶宽、地径、主根长、主根根粗、侧根数、叶绿素含量、氮含量11个指标,采用主成分分析和K值聚类分析对数据进行分析,并结合生产实际,确定蒜头果种苗分级标准。确定株高、主根长、地径作为蒜头果种苗分级标准,将蒜头果种苗划分为3级。Ⅰ级种苗株高≥33.33 cm、主根长≥8.00 cm、地径≥0.23 mm,Ⅱ级种苗33.33 cm>株高≥27.77 cm、8.00 cm>主根长≥7.90 cm、0.23 mm>地径≥0.21 mm,Ⅲ级种苗27.77 cm>株高≥21.29 cm、7.90 cm>主根长≥6.41 cm、0.21 mm>地径≥0.19 mm。本研究制定的蒜头果种苗质量标准符合生产实际,可为蒜头果种苗生产提供理论依据。

Abstract:

Quality grading standards for Malania oleifera seedlings in line with the actual production needs is formulated, which can provide reference for M. oleifera seedling breeding and standardized production. 20 batches of M. oleifera seedlings were randomly selected from the main production area of M. oleifera in Funing County, Yunnan Province. 11 indicators were measured, including fresh weight, plant height, leaf number, leaf length, leaf width, ground diameter, main root length, main root diameter, lateral root number, chlorophyll content, and nitrogen content. The data were analyzed by using principal component and K-value clustering analysis, and then combined with actual production to determine the grading standards of M. oleifera seedlings. M. oleifera seedlings were divided into three levels with determining plant height, main root length, and ground diameter as the grading standards. Grade I seedlings: plant height≥ 33.33 cm, main root length≥ 8.00 cm, ground diameter≥ 0.23 mm; Grade II seedlings: 33.33 cm> plant height≥ 27.77 cm, 8.00 cm> main root length ≥ 7.90 cm, 0.23 mm> ground diameter≥ 0.21 mm; Grade III seedlings: 27.77 cm> plant height≥ 21.29 cm, 7.90 cm> main root length≥ 6.41 cm, 0.21 mm> ground diameter≥ 0.19 mm. In this study, the formulation of quality standards for seedlings is coincident with actual production and can provide a theoretical basis for the production of M. oleifera seedlings.
