Momordica charactia lin( Bitter melon) has been the interest of many studies by researchers for a long time due to its very interesting human beneficial properties. It belongs to cucurbitacea family and momordica genus. It is used by human consumption all over the world in different forms such as a vegetable and /or medicine. The researchers have concentrated on the studies on its fruits and some times on its seeds and leaves. The present study is an extensive investigation of the quantitative elements such as Ca, Cd ,Co, Cr, Cu, Fe, Mg, Mn, Pb, Zn, K, N, and P of the fruit- skin, fruit-flesh, fruit-seed, tissue skin, leaf and root of the momordica charantia lin using flame atomic absorption spectrometry. The result shows a quite good variation of the concentration of the elements in different part of the plant.

Vegetative compatibility groups (VCGs) were studied in 57 Fusarium oxysporum isolates from Momordica charantia L. (bitter gourd) and Lagenaria siceraria (Mol.) Standley (bottle gourd) using nitrate-non-utilizing (nit) mutants. Out of these, 24 isolates that sectored frequently in chlorate medium were genetically unstable and not further used in the experiment. Only 32 isolates were used, among them 21 from F. oxysporum f. sp. momordicae and 11 from F. oxysporum f. sp. lagenariae. Sixty one nit mutants were generated from 21 isolates F. oxysporum f. sp. momordicae with their respective frequencies: nit1 (31), nit3 (11), nit M (19). Twenty five nit mutants were generated from 11 isolates of F. oxysporum f. sp. lagenariae with their respective frequencies: nit1 (13), nit3 (5), nit M (7). F. oxysporum f. sp. momordicae populations have higher frequency of reversion to wild type (39.4%) than F. oxysporum f. sp. lagenariae (27.3%). Non-reverted mutants were used in complementation tests. Four VCGs of F. oxysporum f. sp. momordicae were identified with the majority belonging to a single VCG. Five VCGs of F. oxysporum f. sp. lagenariae were identified. Low VCG diversity ratio (VCGdiv = 0.19) was observed for F. oxysporum f. sp. momordicae whereas a higher value (VCGdiv = 0.45) was obtained for F. oxysporum f. sp. lagenariae. F. oxysporum f. sp. momordicae and F. oxysporum f. sp. lagenariae isolates were not vegetatively compatible.

The aim of this paper is investigating the micromorphological properties of fruits and seeds in the food and medicinal plant Momordica charantia L. (Cucurbitaceae). A detailed anatomical description on cross-sections of immature fruits and seeds is reported for the first time. The fruit is characterized by a thin epicarp, a multi-layered mesocarp and by an inconspicuous endocarp. The seed-coat displays a pattern of organization in five tissues. These endomorphic features were compared and discussed with the results of previous investigations on other representatives of the genus Momordica. Since the structure of seed-coat is considered diacritical in the taxonomy of the genus, this report may offer a set of additional character useful for the characterization of the genus.
