摘要
摘要水叶(Talinum triangulare (Jacq.) wild)是一种功能蔬菜。三角参含有黄酮类和花青素，具有抗氧化和保护心脏的作用。本研究旨在研究遮荫胁迫对三角叶青芽产量和黄酮类化合物含量的影响。该实验于2016年3月至9月在日惹LPP的教学农场理工学院进行。试验采用单因素随机区组设计。本实验采用无遮光和遮光两种处理方法。每次治疗重复3次。结果表明，遮荫使三角叶参的芽产量下降82.51%。遮荫使b叶绿素含量和叶绿素b/a比值高于未遮荫。遮荫增加了黄酮类总含量。关键词:花青素、苯丙素、弱光强、次生代谢物、三角Talinum野生的)merupakan salah satu jenis sayuran fungional。黄芪黄酮类化合物、黄芪黄酮类化合物、黄芪黄酮类化合物、黄芪黄酮类化合物、黄芪黄酮类化合物、黄芪黄酮类化合物、黄芪黄酮类化合物、黄芪黄酮类化合物、黄芪黄酮类化合物、黄芪黄酮类化合物、黄芪黄酮类化合物。Penelitian ini bertujuan untuk menerangkan反应产物pucuk dan kandungan类黄酮tanaman kolsom pada pemberian naungan。Percobaan ini dilakukan di Politeknik LPP日惹，dari bulan市场，2016年9月。龙龙球，龙龙球，龙龙球，龙龙球，龙龙球，龙龙球，龙龙球，龙龙球，龙龙球。Setiap perlakuan diulang tiga kali sehinga total terdapat an satuan percobaan。Pemberian naungan paret 82.51% menurunkan producksi pucuk kolesom。Kandungan klorofil b dannisbah klorofil b/a pucuk kolesom yang ternaungi lebih tinggi dibandingkan dengan tanpa naungan。干干总黄酮。Kata kunci: antosianin, fenilpropanoid, intensitas cahaya rendah, metabolitsekunder, talinululare

ABSTRACT Waterleaf (Talinum triangulare (Jacq.)Willd) is one of functional vegetable. T. triangulare contains flavonoid and anthocyanin that have function as antioxidant and cardioprotective. This research was aimed to study and provide information about the effect of shading stress on shoot production and flavonoid content of T. triangulare shoot. This experiment was conducted at Teaching Farm Polytechnic of LPP Yogyakarta, from March until September 2016. The experiment was laid out in randomized block design with single factor. There were two treatments that used in this experiment (without shading and shading). Each treatment was repeated three times. The result showed that shading 82.51% decrease shoot production of T. triangulare. Shading gave b chlorophyll content and chlorophyll b/a ratio higher than without shading. Shading increase flavonoid total content. Keywords: anthocyanin, fenilpropanoid, low light intensity, secondary metabolite, Talinum triangulare ABSTRAK Kolesom (Talinum triangulare (Jacq.) Willd.) merupakan salah satu jenis sayuran fungsional. Tanaman kolesom megandung senyawa flavonoid dan antosianin yang berperan sebagai antioksidan dan cardioprotective. Penelitian ini bertujuan untuk menerangkan respon produksi pucuk dan kandungan flavonoid tanaman kolesom pada pemberian naungan. Percobaan ini dilakukan di Politeknik LPP Yogyakarta, dari bulan Maret sampai September 2016. Percobaan ini menggunakan rancangan acak kelompok faktor tunggal yang terdiri dari dua taraf perlakuan, yaitu tanpa naungan dan naungan paranet. Setiap perlakuan diulang tiga kali sehingga total terdapat enam satuan percobaan. Pemberian naungan paranet 82.51% menurunkan produksi pucuk kolesom. Kandungan klorofil b dan nisbah klorofil b/a pucuk kolesom yang ternaungi lebih tinggi dibandingkan dengan tanpa naungan. Naungan meningkatkan kandungan total flavonoid. Kata kunci: antosianin, fenilpropanoid, intensitas cahaya rendah, metabolit sekunder, Talinum triangulare
