Cucurbitaceous vegetables

Sex manipulation is attributed to alter the ratio of male to female flowers within the individuals. A wide range of variation in sex forms ranging from primitive hermaphrodite to gynoecious advanced sex form is observed in cucurbitaceous vegetable crops. Sex expression in cucurbitaceae family is regulated by environmental, genetic and hormonal factors. In general, female sex expression is promoted by low temperature and short photoperiod, which may influence the level of endogeneous hormones (ethylene, auxin and GA) which in turn influence the sex expression.

A study was carried out to determine the graft compatibility of bitter gourd scions (Palee F1 and CO 1) with ten different cucurbitaceous rootstocks. The grafting technique adopted in this study was side grafting. Graft compatibility was determined by assessing the survival rate of the grafted plants after regeneration of vascular bundles across the graft interface and vegetative growth of the scion.

Pointed gourd (Trichosanthes dioica Roxb.) is a tropical perennial cucurbitaceous vegetable crop, commonly called as „Parval‟. It has very high nutrient content as compared to other cucurbits. Protein content of pointed gourd is 10 times that of bottle gourd and 4 times that of snake gourd, ridge gourd and wax gourd. Pointed Gourd is cultivated in spring-summer and rainy season in Odisha‟s weather condition but gives higher yield in spring-summer season.

Presently, in South Asian countries, majority of cucurbitaceous vegetables are extensively being grown in riverbeds (called diara land) for off season produce. Growing cucurbitaceous vegetables on river-beds or river basins constitute a distinct type of farming. River bed cultivation is a kind of vegetable forcing is being used in India facilitating off season production of cucurbitaceous vegetables, where cucurbits are grown in the river beds during winter season.

(Cucumis sativus L.) is one of the oldest cultivated vegetable crops belongs to the family cucurbitaceous with 7 pairs of chromosomes and several distinct morphological features stands apart from other species with 12 pairs of chromosomes which are indigenous to tropical Africa. Now a day’s powdery mildew has become a major disease in cucumber, since there is no detailed quantitative information on effective management of the disease resistance genotypes plays an important role to combat against pathogen.

Ridge gourd is an important cucurbitaceous vegetable, which is an annual herbaceous plant with creeping and climbing habit. Most of the farmers’ traditionally cultivating ridge gourd on soil surface with surface irrigation. Farmers are getting not only less yields but also inferior quality fruits with this method of cultivation. This may be due to incidence of more soil borne pests and diseases and unsuitable growing condition to both vine and fruits when compared to trellis or pandal system of cultivation.
