THE INFLUENCE OF SALTS STRESS ON SOME GROWTH MORPHOLOGY OF (MELON PUMPKIN) Cucurbita maxima Duchesne GROWN IN-VITRO
*Umoh, S. F., Okon, J. E. and Ekpe, E.
ABSTRACT
The influence of different salts (KH2PO4, CaCl2 and MgSO4) stress on
some growth morphology of (Melon Pumpkin) Cucurbita maxima
were studied in-vitro in the laboratory. Melon pumpkin seeds were
surface sterilized and then sown into petric dishes packed with cotton
wool. Growth parameters were determined two weeks after
germination using standard procedures. The morphological studied
included seedling height, leaf area, root length, percentage germination
and moisture content. Salts salinity has deleterious effects on many food crops especially in
morphology of the plants. It was observed that with the increase in salinity levels plants
growth was adversely affected which showed the melon pumpkin was highly sensitive to
salinity and increased level of salinity has lethal effects on it resulted reduction in growth
parameters. This results is of great economic significance to abiotic stresses like water stress,
salt stress, metal stress etc., can cause an increase in the active principle contents in medicinal
plants and this will be helpful for the cultivation of this plant in salt affected areas.
Keywords: Cucurbita maxima, morphology, salt stress, parameters.
