Abstract
Basil is a plant that produces essential oils. The synthesis of essential oils is influenced by environmental factors such as light and temperature. Giving shade can affect the intensity of light and temperature received by plants. The purpose of this study was to examine different shading effects on growth and oil yield. This study is an experimental study using a completely randomized design (CRD) with a single pattern, namely shade with growth parameters and a factorial pattern with the first factor being shade and the second factor being plant organs with essential oil yield parameters. Planting is done by sowing the seeds for 2 weeks then transferred them to polybags measuring 30 cm x 30 cm which contains planting media in the form of a mixture of soil, coco peat, roasted husks, and compost in a ratio of 1:1:1:1 and given 30 g of manure. Shade treatment used 0%, 25%, and 50% shade to determine the effect of growth, while the oil yield was taken from the leaves, stems, and flowers to determine the interaction between shade and organ essential oil yield. Data were analyzed using Analysis of Variance (ANOVA) with a 95% confidence level, and if there was a significant difference, it was continued with Duncan's Multiple Range Test (DMRT). Parameter data taken were the number of leaves, time of flower initiation, plant height, number of primary branches, leaf area, dry weight, wet weight, and essential oil yield (leaves, stems, and flowers). The results showed that there was a significant effect on the parameters of plant height, leaf area, flower initiation time, and essential oil yield. The highest oil yield was in the flower parts of plants with 50% shading.
罗勒是一种生产精油的植物。精油的合成受光照、温度等环境因素的影响。遮荫会影响植物接收到的光照强度和温度。本研究的目的是研究不同遮荫对油菜生长和产量的影响。本研究是采用完全随机设计(CRD)的实验研究,采用单一模式,即遮荫与生长参数,以及第一因素为遮荫,第二因素为植物器官与精油产量参数的析因模式。播种两周,然后将种子转移到30厘米× 30厘米的塑料袋中,塑料袋中含有土壤、可可泥炭、烤壳和堆肥的混合物,比例为1:1:1:1,并给予30克粪肥。遮荫处理使用0%、25%和50%遮荫来确定生长效果,而从叶、茎和花中提取油产量来确定遮荫与器官精油产量之间的相互作用。采用95%置信水平的方差分析(ANOVA)对数据进行分析,如果存在显著差异,则继续采用Duncan's Multiple Range Test (DMRT)进行分析。采集的参数数据为叶片数、开花时间、株高、一次枝数、叶面积、干重、湿重、精油产量(叶、茎、花)。结果表明:植物株高、叶面积、开花时间、挥发油产率等参数均受到显著影响。遮荫50%的植株的花部含油量最高。
