BACKGROUND AND AIMS Watermelons, Citrullus species (Cucurbitaceae), are native to Africa and have been cultivated since ancient times. The fruit flesh of wild watermelons is watery, but typically hard-textured, pale-coloured and bland or bitter. The familiar sweet dessert watermelons, C. lanatus, featuring non-bitter, tender, well-coloured flesh, have a narrow genetic base, suggesting that they...

BACKGROUND AND AIMS The watermelon, Citrullus lanatus (Cucurbitaceae), is an important fruit vegetable in the warmer regions of the world. Watermelons were illustrated in Mediterranean Antiquity, but not as frequently as some other cucurbits. Little is known concerning the watermelons of Mediterranean Europe during medieval times. With the objective of obtaining an improved understanding of wat...

We derive asymptotics for the moments of the height distribution of watermelons with p branches with wall. This generalises a famous result by de Bruijn, Knuth and Rice [2] on the average height of planted plane trees, and a result by Fulmek [6] on the average height of watermelons with two branches.

Gillet [3] demonstrated that limn→∞Wk(b2n tc)/ √ 2n tends to a family of p nonintersecting Brownian excursions, 0 ≤ t ≤ 1, as an extension of a principle given in [4]. The height of a path Wk in a p-watermelon with wall is the maximum value of Wk(i) over all i. The area under a path Wk is the area of the polygonal region determined by the curve j = Wk(i), the horizontal line j = 0, and the vert...

Using path-integral techniques, we compute exactly the distribution of the maximal height Hp of p nonintersecting Brownian walkers over a unit time interval in one dimension, both for excursions p watermelons with a wall, and bridges p watermelons without a wall, for all integer p>or=1. For large p, we show that approximately square root 2p (excursions) whereas approximately square ro...

A watermelon is a set of p Bernoulli paths starting and ending at the same ordinate, that do not intersect. In this paper, we show the convergence in distribution of two sorts of watermelons (with or without wall condition) to processes which generalize the Brownian bridge and the Brownian excursion in Rp. These limit processes are defined by stochastic differential equations. The distributions...

Watermelon grafting is practiced in order to improve tolerance poor environments such as low temperature. This study was conducted investigate the effect of low-temperature tolerant bottle gourd (Lagenaria siceraria) rootstocks on growth and fruit quality watermelon semi-forcing retarding culture where plants were exposed or high Five accessions (FR79, IT207112, BG702, BG703, FRD22) with temper...

Watermelon (Citrullus vulgaris Schrad.) is a natural and rich source of the non-essential amino acid citrulline. Citrulline is used in the nitric oxide system in humans and has potential antioxidant and vasodilatation roles. A method using gas chromatography-mass spectrometry (GC-MS) was developed to separate citrulline from glutamic acid, which co-elute when analyzed by high performance liquid...
