摘要

為研究不同光質對草莓‘豐香’營養生長與種苗生產之影響，利用三種不同光質之發光二極體（LED），6R2B1IR（紅光：藍光：紅外光＝6：2：1）、7RGB（紅光：藍光：綠光＝7：1：1）與CW（全波長，冷白光），栽培草莓植株6週，探討紅外光之添加對草莓生長與種苗生產之促進效果。試驗結果顯示添加10%紅外光之6R2B1IR處理下植株葉片厚度較薄，但葉柄數、葉面積、植株生物量、光合作用能力、生理代謝物含量及走莖生成皆較高，同時所產出之走莖苗生長亦較佳，表示添加適當紅外光成分可促進草莓‘豐香’之生長與走莖生成，進而增加種苗生產效益。

This study was aimed at investigating the effects of light quality of Light Emitting Diodes (LED) on plant growth and runner propagation of strawberry 'Toyonoka'. Strawberry plants were cultured under three different light qualities of LED, 6R2B1IR (red: blue: infrared = 6:2:1), 7RGB (red: blue: green = 7:1:1) and CW (full wave length, cool white), for 6 weeks to understand if the addition of infrared in red and blue light could promote strawberry propagation. The greatest leaf number, leaf area, biomass, photosynthesis, photosynthetic pigment content, photosynthate, runner and ramet production were shown in 6R2B1IR treatment (addition of 10% infrared). However, the leaf was thin. The results showed that supplemental infrared light could promote plant growth and runner production of strawberry 'Toyonoka', thus increase the benefit of seedling productivity.
