Abstract

Durio zibethinus L. is known as the “king of fruit” in Malaysia. Meanwhile, Jelebu, Negeri Sembilan has always become the top choice district to visit for durian lover for its Durian Kampung Jelebu, which possessed good quality on par with top D. zibethinus clones such as D197 Musang King and D24. However, there is still lacking in taxonomic data of D. zibethinus especially from Jelebu. This study aimed to analyse the leaf architecture and genome size variations of selected D. zibethinus accessions from Jelebu. Five D. zibethinus accessions from Jelebu were examined. Thirty-seven parameters of gross leaf morphological characteristics and leaf venation pattern were observed and recorded for identification and classification of D. zibethinus accessions from Jelebu. Seven parameters have been recorded which are petiole length, petiole features, leaf size, leaf shape, leaf base shape, lower leaf surface colour and areolation could be used in differentiating between accessions. Results of this study showed the intraspecific variations existed among D. zibethinus accessions from Jelebu with a genome size varying between 1.7433 pg and 1.800 pg. In conclusion, data on leaf architecture and genome size variations from D. zibethinus accessions are beneficial for early plant identification and classification.

马来西亚森美兰州 Jelebu 的 Durio zibethinus L. 的叶片结构和基因组大小变异

榴莲（Durio zibethinus L.）被誉为马来西亚的 "水果之王"。与此同时，森美兰州的热勒布（Jelebu）一直是榴莲爱好者的首选地区，因为这里的榴莲甘榜热勒布（Kampung Jelebu）拥有与顶级榴莲克隆品种（如 D197 Musang King 和 D24）相媲美的优良品质。然而，关于榴莲的分类学数据仍然缺乏，尤其是来自热勒布的数据。本研究旨在分析杰莱布所选 D. zibethinus 接种的叶片结构和基因组大小变化。研究考察了来自热勒布的 5 个 D. zibethinus 品种。观察并记录了叶片形态特征和叶脉图案的 37 个参数，以便对热勒布的 D. zibethinus 插种进行鉴定和分类。所记录的叶柄长度、叶柄特征、叶片大小、叶片形状、叶基部形状、下部叶片表面颜色和隔离度等七个参数可用于区分不同品种。研究结果表明，杰莱布的 D. zibethinus 种间存在种内差异，基因组大小在 1.7433 pg 和 1.800 pg 之间。总之，D.zibethinus 入选品种的叶片结构和基因组大小变异数据有利于植物的早期鉴定和分类。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
