The most of morphological, floral parameters, total chlorophyll, carotenoids, and anthocyanin pigment contents in the flower recorded increment by most treatments of laser types. The highest survival percentage of acclimatized plants (95%) and highest values of number of branches and branches length (cm) were obtained from treated plantlets by 20 min of green laser, while most of highest floral parameters, anthocyanin pigment contents in flower, and anatomical structural parameters recorded increasing using 20 min of blue laser and 20, 25 min of green and red laser, respectively. Contrary, the lowest values of photosynthetic pigments and carotenoids were obtained from 20 min of green ...
