【 摘 要 】

Mentha arvensis was used as plant models as it can respond typically to different environmental conditions by marked alterations in growth rate. Among the environmental factors affecting growth rate, light eternally at an improper level. In nature, the intensities are overhead of the saturation point and might high enough to inhibit the growth during substantial of the day. Such information is rudimentary to the evaluation of physiological studies and this parameter is less studied on M. arvensis. Thus, this study describes the growth response of M. arvensis to different light intensities. In order to determine the effect of different light intensity on their growth rate, (50%, 70% and 100 %) of full ambient light (FAL) were introduced to the plant after they were grown using stem. The treatment were introduced after a month of germination. Furthermore, to observe their growth rate, few parameters were taken as the fresh and dry weight, plant height, number of leaves and branches were measured for each treatment. As a consequence, the 100% of FAL treated plants showed the highest mass for fresh (3.3275 g) and dry weight (0.932 g). However, 50% of FAL treated plant showed the highest result for the plant height, number of leaves and branches, compared to 70% and 100% of FAL treatment. Therefore, Mentha arvensis is best grown under low light intensities.
