LED光源對離體培養之‘貝利A’葡萄生長及形態之影響

TL;DRAbstract

Two-node microcuttings were used in this study to evaluate the effect of different LED lights on growth and morphogenesis of ‘Muscat Bailey A’ grapevines cultured in vitro. Among mono-wavelength and white LEDs treatments, the results showed that different light sources had significantly different effects on the rates of shoot regeneration and rooting. The percentages of shoot regeneration and rooting in the treatment of 9R (100% red light) were the highest and the lowest ones were obtained in the 9IR (100% infrared light) treatment. Plants in the WW (warm white light) treatment had the highest fresh weight and dry weight of shoot, node number, shoot length, internode length and root length. The root fresh weight and root dry weight were higher in the treatment of CW (cool white light) than in other treatments. Plants in the treatment of 9B (100% blue light) had a higher leaf color than those in other treatments. The chlorophyll content in the 9B treatment was also the highest. There wa
