The College of Science at the University of Basrah organized a seminar entitled(Effect of UV – Radiation on Morphological, Anatomical and Biochemical Characteristics of Palm Seedlings...) by the graduate student . SajedaYaseenSwiad... The study aims to investigate the effect of different UV-B doses(2, 4, 8 and 10 hrs. day-1) on some anatomical and biochemical characteristics of the seedlings of two palms genus Date Palm (Phoenix dactylifera L.) and Desert Fan Palm Washingtonia filifera(Lindl.) H. Wendl, present investigation concluded that morphological features and biomass of both species were unaffected with low dose of UV-radiation (2hrs.day-1). But, date palm (P. dactylifera L.) was capable to survive at high dose of radiation (8 hrs.day-1) for 30 days. and the study was recommended ...... (UV-B resistance between palm species or date palm cultivars is a crucial factor and needs more investigations. But, the results of the present work open the possibility future work for selecting the palm species that able to survive under UV-B radiation. Moreover, current study invites all research workers to focusing their studies towards the UV-B photoreceptor. Where, this receptor
triggers morphological and physiological changes to attenuate the UV radiation.
However, with respect to the important factor, that governs the response of plants to UV-B stress. Scientist found a relationship between UVR8 (signaling protein) and triggers
of various morphological and physiological changes in plants to stand up against such
stress. In palms, this needs much intensive investigations on the molecular
level.)
