英文摘要Variations in fruit size, color, and stripe pattern on fruit rinds have been noticed among individuals within Citrullus colocynthis (Cucurbitaceae) populations in the hyper-arid deserts of the UAE. The present study aimed at assessing variations in fruit and seed characters, germination behavior, and genetic diversity among 12 individuals (hereafter referred accessions) collected from one population. Results showed that the accessions differed in seed dormancy level and response to light and temperature of incubation. The overall germination ranged between 18.5% in accession number 9 and 56.6% for accession number 2. At lower temperatures (15/25 degrees C), little germination occurred in darkness but not in the light. Germination was significantly greater and faster (germination rate index was higher) at higher temperatures (25/35 degrees C) than moderate (20/30 degrees C) and lower temperatures. Germination was greater in light than darkness in almost all accessions at higher temperatures but not at moderate temperatures. Random amplified polymorphic DNA (RAPD) analysis showed polymorphism varied between 90 and 100%, with polymorphic information content values ranged from 0.28 to 0.37 with an average of 0.33. Few individuals showed high genetic similarities, while most of them had similarity coefficients less than 0.5. There were moderate to weak relationships between genetic similarities and germination behavior of the different accessions.
