Melatonin and GABA are two stress plant hormones whose mission is to protect plants against saline, thermic or hydric stress. However, there are not studies that analyze the role of these hormones in plant development and inflorescence. Using Zea mays (corn) seeds, Phalaris canariensis (canaryseed) seeds and Kalanchoe daigremontiana seedlings we have demonstrated that melatonin diminishes stem growth and increases root growth. Moreover. We have also exposed that melatonin diminished Mirabilis jalapa inflorescences. As a conclusion, melatonin has an important and previously undocumented role in plant growing and inflorescence.
