“…Watermelon is produced mainly for fresh fruit market, with countries such as China, Turkey, Russia, Iran and Brazil being the most important growers, respectively (FAOSTAT, 2007). Seedless watermelon has increased in preference by consumers, and in United States as an example, the seedless fruits corresponds to over 90% on total commercialization (SARGENT & MAYNARD, 2009).…”

Watermelon (Citrullus lanatus (Thunb.) Matsum & Nakai) seedlings generally present issues regarding to seed coat adherence to cotyledons at the emergence stage. In this case, the seed coat acts as a barrier for seedling development, which may result in stretched or malformed seedlings. Therewith, this study was carried out to evaluate the effects of seed orientation in the substrate on seedling emergence and growth, and also to evaluate the effect on seed coat adherence. Diploid, triploid and tetraploid watermelon seeds were used in this study. The treatments were composed of four seed lots and three different seed orientations at sowing: hilum pointed upwards (HUp), hilum pointed downwards (HDown) and hilum pointed horizontally (HHor). The evaluations consisted of: seedling emergence, seedling speed index, seedling height, seedling dry mass and seed coat adherence to cotyledons. HUp presented lower results for seed coat adherence to cotyledons, but negatively interfered on seedlings emergence and growth. In general, the treatment HHor presented the most satisfactory results, even though it did not solve the seed coat adherence issue.

Pumpkins are difficult to produce for fall markets in the southeastern United States. Diseases, particularly aphid (Myzus persicae and Aphis spp.)-transmitted virus diseases, make fall pumpkin production difficult. Controlled-atmosphere (CA) storage may offer a method of overcoming this problem by using spring-or summer-produced pumpkins held in CA storage for fall sales. The objective of this study was to evaluate CA storage of pumpkins from spring and summer production. Pumpkins (Cucurbita pepo L.) were stored under ambient conditions (≈ 70-90 • F, ≈ 40%-60% relative humidity [RH]) and CA conditions (3% O 2 , 5% CO 2 , 50 • F, and 60% RH) to compare postharvest storage and shelf life. Pumpkins stored under CA conditions had significantly less damage than pumpkins stored under ambient conditions. There were significantly more marketable fruit after CA storage. Cultivar did not affect results. Although there were differences between storage methods, CA-stored pumpkins still had significant loss due to fungal pathogen activity. In 2007, 14% of pumpkins from CA storage were unmarketable fruit, with an additional 55% showing some damage. In 2008, 40% of pumpkins stored under CA conditions were unmarketable. Additional steps including surface sanitization would likely be required prior to widespread adoption of this technology.

“…agrestis (Burger et al, 2010). The most commonly cultivated melon type in the United States is cantaloupe (Reticulatus group) (Sargent and Maynard, 2009). In 2011, 72,690 acres of cantaloupe were planted in the United States with a production value of $350 million [U.S. Department of Agriculture (USDA), 2013].…”

Interest in producing specialty melons (Cucumis melo) is increasing in Florida, but information on yield performance, fruit quality, and disease resistance of specialty melon cultivars grown in Florida conditions is limited. In this study conducted at Citra, FL, during the 2011 Spring season, 10 specialty melon cultivars were evaluated, in both certified organic and conventionally managed fields, including: Creme de la Creme and San Juan ananas melon (C. melo var. reticulatus), Brilliant and Camposol canary melon (C. melo var. inodorus), Ginkaku and Sun Jewel asian melon (C. melo var. makuwa), Arava and Diplomat galia melon (C. melo var. reticulatus), and Honey Pearl and Honey Yellow honeydew melon (C. melo var. inodorus). ‘Athena’ cantaloupe (C. melo var. reticulatus) was included as a control. ‘Sun Jewel’, ‘Diplomat’, ‘Honey Yellow’, and ‘Honey Pearl’ were early maturing cultivars that were harvested 10 days earlier than ‘Athena’. ‘Athena’ had the highest marketable yield in the conventional field (10.7 kg/plant), but the yield of ‘Camposol’, ‘Ginkaku’, ‘Honey Yellow’, and ‘Honey Pearl’ did not differ significantly from ‘Athena’. Under organic production, ‘Camposol’ showed a significantly higher marketable yield (8.3 kg/plant) than ‘Athena’ (6.8 kg/plant). ‘Ginkaku’ produced the largest fruit number per plant in both organic (10 fruit/plant) and conventional fields (12 fruit/plant) with smaller fruit size compared with other melon cultivars. Overall, the specialty melon cultivars, except for asian melon, did not differ significantly from ‘Athena’ in terms of marketable fruit number per plant. ‘Sun Jewel’, ‘Diplomat’, and ‘San Juan’ showed relatively high percentages of cull fruit. ‘Honey Yellow’, ‘Honey Pearl’, and ‘Sun Jewel’ exhibited higher soluble solids concentration (SSC) than ‘Athena’ in both organic and conventional fields, while ‘Brilliant’, ‘San Juan’, and ‘Ginkaku’ also had higher SSC than ‘Athena’ under organic production. ‘Honey Yellow’, ‘Sun Jewel’, ‘Brilliant’, and ‘Camposol’ were less affected by powdery mildew (caused by Podosphaera xanthii) and downy mildew (caused by Pseudoperonospora cubensis) in the conventional field. ‘Honey Yellow’ and ‘Camposol’ also had significantly lower aboveground disease severity ratings in the organic field compared with ‘Athena’, although the root-knot nematode (RKN) (Meloidogyne sp.) gall rating was higher in ‘Honey Yellow’ than ‘Athena’.
