Abstract
Triploid watermelon [ Citrullus lanatus (Thunb.) Matsum & Nakai] consumption is increasing in the United States However, some of the original problems, poor and inconsistent germination, still exist. Seeds of several triploid and diploid watermelon cultivars were subjected to a variety of treatments to improve germination. Control and scarified seeds, by nicking, were incubated at 25 or 30 °C in either 5 or 10 mL H 2 O or hydrogen peroxide (H 2 O 2 ). Triploid seed germination was strongly inhibited in all cultivars when seeds were at 10 mL of H 2 O or H 2 O 2 ; both nicking and H 2 O 2 increased germination but not equal to rate of the control in 5 mL H 2 O or H 2 O 2 . Germination of diploid cultivars was unaffected by any treatment. Seed morphological measurments indicated that triploid seed has a smaller embryo with a large and highly variable ( cv = 105%) air space surrounding the embryonic axis as compared with the diploid seed. These data suggests that triploid watermelon seed germination is not inhibited by the seed coat thickness alone. Seed moisture plays a significant role in germination, emergence, and stand uniformity.
