Abstract:

Watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] is a plant of Cucurbitaceae family which is include in an annual plant. In Indonesia, watermelon has diversity in its cultivar as can be seen from the stem, leaf, flower, and fruit morphology. This research is aimed to find out the diversity and the similarity relationship of watermelon cultivar in Nusawungu, Cilacap. A survey method was used in this research by taking the samples with a random sampling technique (purposive sampling). This research parameter consisted of stem, leaf, flower, and fruit morphology of each watermelon cult

Abstract:

As triploid watermelons (Citrullus lanatus) increase in popularity, production has shifted away from seeded watermelons. To achieve successful fruit set in triploid watermelons, a diploid watermelon cultivar must be planted as a pollen source. Three diploid cultivars in 2005 and seven diploid cultivars in 2006 were evaluated at one and three locations, respectively, to determine their effectiveness as pollenizers. Each cultivar was planted within plots of the triploid watermelons ‘Tri-X 313’ (2005) and ‘Supercrisp’ (2006) with buffers on all sides of the plots to contain pollen flow within ind

Abstract:

Gummy stem blight caused by Didymella bryoniae is one of the diseases that cause significant economic losses in watermelon cultivation. To define the resistance characteristics of watermelon cultivars to D. bryoniae, we investigated virulence of six D. bryoniae isolates in three susceptible cultivars of watermelon. And, we selected six moderately resistant and less susceptible watermelon cultivars to D. bryoniae and investigated occurrence of gummy stem blight on seedlings of the cultivars caused by six isolates of D. bryoniae. The isolates represented different virulence in the susceptible cu

In the Spring and Fall 2006, the pollen viability of four diploid watermelon pollenizers was evaluated in Quincy, FL. Triploid watermelon plants [Citrullus lanatus (Thunb.)

Recent studies have illustrated differences in triploid watermelon yields as a result of the pollenizer cultivar used. The viability of the pollen produced by pollenizer cultivars may greatly influence the fruit set and fruit quality in the triploid watermelon crop. Pollen sam

Successful fruit set in triploid watermelons [Citrullus lanatus (Thunb.) Matsum. & Nakai] requires a diploid watermelon cultivar, or pollenizer, to be planted nearby as a pollen source. Pollenizer cultivars have been developed to be planted in-row with triploid plants without spacing change, which decreases area per plant. These cultivars have different growth habits, from highly reduced foliage to standard foliage, and it is uncertain how pollenizer growth habit may affect triploid plant growth and yield.

Abstract:

The rising temperatures and reduced rainfall because of climate change have contributed to severe droughts which subsequently affect crop production leading to global food insecurity. One crop particularly vulnerable to these changes is watermelon, a nutritious fruit rich in vitamins and antioxidants, but highly sensitive to water scarcity. Insufficient moisture during the crop establishment period results in a less vigorous plant leading to reduced yield thus it is crucial to develop strategies that can reduce the effects of drought stress. Grafting is one strategy used and has proven to be i

The discovery of several waterlogged plant remains in a Middle Ages context (1330–1360 AD) in Sassari (NS, Sardinia, Italy) enabled the characterisation of archaeological plum fruit stones and watermelon and grape seeds through computer image analysis. Digital seed/endocarp images were acquired by a flatbed scanner and processed and analysed by applying computerised image analysis techniques. The morphometric data were statistically elaborated using stepwise linear discriminant analysis (LDA), allowing comparisons among archaeological remains, wild populations and autochthonous cultivars.

Abstract:

The past 10 years has seen a steep increase in production of seedless watermelon (Citrullus lanatus) in the United States. Seedless fruit is produced on triploid plants that require pollination from diploid pollenizers for fruit set. Synchronization of the staminate flowers on the pollenizers with the appearance of pistillate flowers on the triploids is a fundamental requirement for this production system. Previous research suggested that pistillate flowers reach peak production early in the season, but data are only available for a small number of triploid cultivars. We compared the flowering
