5种天南星科观赏植物水培试验

Hydroponic culture of five species of Araceae plants

摘要

摘要: 对黑叶观音莲(A locasia 伊 amazonica)、红掌（A nthurium andraeanum）、玛丽安万年青（Dieffenbachia耶Camilla爷）、袖珍龟背竹（Monstera oblique 耶Dwarf爷）和小天使（Philodendron 耶Xanadu爷）等 5 种植物以 3 种浓度的NAA 和 3 种营养液进行水培试验，通过测定形态指标和生理指标，探讨最佳的 NAA 浓度和营养液配方。结果表明，除袖珍龟背竹在 15 mg/LNAA 条件下生根效果最好外，其他植物的最适浓度均为 10 mg/L；最佳营养液配方为：玛丽安万年青、黑叶观音莲和小天使为霍格兰配方，袖珍龟背竹为斯泰纳配方，红掌为日本园试配方。

Abstract: Hydropnic experiment on five species of Araceae plants, including Alocasia amazonica, Anthuriumandraeanum, Dieffenbachia Camilla , Monstera oblique Dwarf and Philodendron Xanadu with threeconcentrations of NAA and three kinds of nutrient solution was carried out. Through measuring the morphological andphysiological indexes, the optimum concentration of NAA and nutrient solution for the five species of Araceae plantswas found out. The results showed that the optimum concentration of NAA for M. Oblique Dwarf was 15 mg/L, whilefor other plants was 10 mg/L. Hoagland nutrient solution was the best hydroponic solution for Alocasiaamazonica,Dieffenbachia Camillaand Philodendron Xanadu. Steiner nutrient solution was the best for M. oblique Dwarf.Japanese garden general nutrient solution was the best for A. andraeanum.
