We studied the diversity of beetle families in watermelon fields palm grove Zaatote at Ouargla (34º 54′ N, 5º 20′ E). The sampling method used was Barber pots as they allowed largest number captures insects, regarding both individuals and species. Over three years study (2016, 2017 2018), we identified 787 from 12 taxonomic families. Throughout period, Coccinellidae family clearly dominant, wit...

In this study, the characteristics of tetraploid and diploid watermelon’s flowers, fruits, seeds were examined, their differences investigated. As plant material, ST101 ST82; WL92, WL124, WL134, WL216, WL259-B WL235 used. Flower (pollen viability, pollen germination, number anthers per anther flower); fruit (weight, length, diameter, rind thickness TSS) seed (weight 1000 seed, width, thickness,...

An unusual seed mutant in watermelon (Citrullus lanatus var. lanatus) has seeds with a fleshy pericarp, commonly called egusi seeds. The origin of the phenotype is unknown, but it is widely cultivated in Nigeria for the high protein and carbohydrate content of the edible seeds. Egusi seeds have a thick, fleshy pericarp that appears during the second to third week of fruit development. We studie...

Watermelon is one of the most important fruit crops in world, but their flowers require bees for pollination. In this study we determine bee species visiting watermelon flowers, daily visits and resource they forage during 84 observation days on Los Santos, Panama. Native bees, especially stingless represented visits, so probably play a very role pollination within zone. The frequent were N. pe...

Abstract Morningglories ( Ipomoea spp.) are among the most troublesome weeds in cucurbits United States; however, little is known about spp. interference with horticultural crops. Two additive design field studies were conducted 2020 at two locations Indiana to investigate of ivyleaf morningglory hederacea Jacq.), entireleaf Jacq. var. integriuscula A. Gray.), and pitted lacunosa L.) triploid w...

Watermelon [Citrullus lanatus (Thunb.) Matsum. and Nakai] plug seedlings were stored at 15°C in the light at a photosynthetic photon flux density of 15 µmol·m(-2)·s(-1) or in darkness for 6 days, to evaluate their chloroplast ultrastructure, and associated photosynthetic characteristics. Storage in the dark caused swelling, disordered granal arrangement, and starch grain disappearance in the ch...
