The first group are annual or short- lived perennial vines and are mesophytic, i. The second group are perennials growing in arid zones and so are xerophytic, tolerating dry conditions.

Cultivated Cucurbita species were derived from the first group. Growing 5 to 1. 5 meters (1. Most species do not readily root from the nodes; a notable exception is C. The vine of the perennial Cucurbita can become semiwoody if left to grow.

Cross pollination does occur readily within the family Cucurbitaceae.

Seeds for studying additional species members were not available. Sixteen of the 2.

Competitively grown specimens are therefore often hand- pollinated to maximize the number of seeds in the fruit, which increases the fruit size; this pollination requires skilled technique. When a plant already has a fruit developing, subsequent female flowers on the plant are less likely to mature, a phenomenon called . The development of female flowers is not yet understood. Seeds planted deeper than 1. In a seed batch with 9.

These effects vary significantly between the different species of Cucurbita. A type of stored phosphorus called phytate forms in seed tissues as spherical crystalline intrusions in protein bodies called globoids. Along with other nutrients, phytate is used completely during seedling growth. Centers of domestication stretch from the Mississippi River watershed and Texas down through Mexico and Central America to northern and western South America. Four of them, C. The domesticated forms of C. He suggested that the crookneck, ornamental gourd, and scallop are early variants and that the acorn is a cross between the scallop and the pumpkin. The wild form C.

Gourds, also called bottle- gourds, which are used as utensils or vessels, belong to the genus Lagenaria and are native to Africa. Lagenaria are in the same family and subfamily as Cucurbita but in a different tribe.

C (2. 0% of the Daily Value, DV), moderate in vitamin B6 and riboflavin (1. DV), but otherwise devoid of appreciable nutrient content (table), although the nutrient content of different Curcubita species may vary somewhat. Cucurmosin is more toxic to cancer cells than healthy cells.

Poisonous to mammals. It makes wild Cucurbita and most ornamental gourds, with the exception of an occasional C. This book contains an illustration known as Quegourdes de turquie, which was identified by cucurbit specialists as C.
