植物在暗置储运过程中,其色素发生变化,致使保鲜质量下降。荷兰瓦赫宁根农业大学的科学家们对此进行了一系列的研究,发现发红光二极管能提高切花保鲜质量。他们发现,淡紫六出花Yellow King品种切花在20℃温度下,暗置水中9天,其叶出现黄化。如在暗置期间补充红光,则能提高其叶绿素含量。朱槿Nairobi品种植株,在20℃温度下,暗置4天,花蕾损失74％如补充红光,损失可减少到31％。 Plants in dark storage and transportation process, the pigment changes, resulting in decreased quality preservation. Scientists at the Wageningen Agricultural University in the Netherlands conducted a series of studies and found that red-emitting diodes can improve the quality of cut flowers. They found that cut flowers of Yellow King, a flower of Lavender, were yellowed in water for 9 days at 20 ° C. If the red light during the dark, it can increase its chlorophyll content. Hibiscus Nairobi varieties of plants, dark place at 20 ℃ for 4 days, 74% loss of buds such as the addition of red light, the loss can be reduced to 31%.
