Abstract

Horticulture is now revolutionized by advancements in light-emitting diode (LED) lighting. New technologies enable knowledge expansion on how plants require different spectral illumination for optimal growth and development. The aim of this study was to evaluate the quality of cucumber (Cucumis sativus L. ‘Parys F1’) and tomato (Solanum lycopersicum L. ‘Poranek’) seedlings produced in indoor controlled conditions, using three different types of LED tubes emitting warm light (AP67, AP673L, and G2). The photosynthetic photon flux density was set at 50–65 µmol m−2 s−1 and a 16-hour light regime was used. The results were compared to the cool daylight-emitting fluorescent (FL) control (tube lamp TLD 36W/54). A detailed analysis of the biometrical parameters of the aboveground and underground parts of seedlings was performed. Moreover, the content of chlorophyll in the leaves was measured. No effect of light spectra on the underground part of cucumber was found. On the other hand, the type of lamp affected the number of leaves and chlorophyll content in this species. Lamps AP673L and FL can be recommended in the production of cucumber seedlings. The obtained seedling had characteristics desired for horticultural production, i.e., compact habit with a fair number of leaves and chlorophyll content. As for tomato, the FL lamp had the best effect on the development of seedlings. Due to the high share of far red light, the tested LEDs stimulated the elongated growth of flaccid plants, unsuitable for commercial producers. Our findings not only described the effect of various light spectra on plant development but can also be useful for producers of popular vegetable crops.

宽光谱发光二极管在黄瓜和番茄幼苗室内生产中的应用

随着发光二极管（LED）照明技术的进步，园艺正在发生革命性的变化。新技术使人们能够了解植物如何需要不同的光谱照明来实现最佳生长和发育。本研究的目的是评估在室内控制条件下生产的黄瓜（Cucumis sativus L.‘Parys F1’）和番茄（Solanum lycopersicum L.‘Poranek’）幼苗的质量，使用三种不同类型的发光二极管管（AP67、AP673L和G2）。光合光子通量密度设定为50–65µmol m−2 s−1，并使用16小时的光照条件。将结果与冷日光发射荧光（FL）对照（筒灯TLD 36W/54）进行比较。对幼苗地上和地下部分的生物特征参数进行了详细分析。此外，还测定了叶片中叶绿素的含量。光谱对黄瓜地下部分没有影响。另一方面，灯的类型影响了该物种的叶片数量和叶绿素含量。AP673L和FL灯可推荐用于黄瓜幼苗的生产。所获得的幼苗具有园艺生产所需的特征，即紧凑的习性，具有相当数量的叶片和叶绿素含量。对于番茄而言，荧光灯对幼苗的发育效果最好。由于远红光的比例很高，测试的LED刺激了松弛植物的伸长生长，不适合商业生产商。我们的发现不仅描述了各种光谱对植物发育的影响，而且对流行蔬菜作物的生产者也很有用。

期刊介绍： The Acta Agrobotanica publishes mainly significant, original research papers presenting the results new to the biology of cultivable or wild plants accompanying crops. The submissions dedicated particularly to flora and phytocenoses of anthropogenically transformed areas, bee pastures, nectariferous and polleniferous taxa, plant-pollinator relationships, urban and rural habitats for entomofauna, cultivated plants, weeds, aerobiology, plant pathogens and parasites are encouraged and accepted. Besides the original research papers, authors may submit short communications and reviews. The journal also publishes the invited papers in case of new developments in plant science. All submissions must be written in good English, which is solely a responsibility of the authors.
