Um Siteih (Corchorus depressus) Germination And Growth In Asandy Soil Under Water

Abstract

A field survey was carried out in Alsabaloga, River Nile State, Sudan, to determine the natural distribution of Um siteih plant and collection of its seeds (Corchorus depressus). A field experiment was also conducted to determine the effect of water stress on the performance of Um siteih plants. The morphological and physiological bases of adaptation were discussed. The results of the field survey indicated that the majority of Um siteih plants were on light soil (sandy soils) compared to with relatively heavy soil (Wadi soil). The seeds of Um siteih plants germinated in a wide range of temperatures (2 oC-45oC), and the percentage of germination was high when the seeds were soaked before sowing. The results indicated that, the water-stressed plants of Um siteih had significantly increased number of stems , leaves, root length, flowers, pods, fresh weight of stems, dry weight of Please purchase PDFcamp Printer on http://www.verypdf.com/ to remove this watermark. IX stems, fresh weight of roots and dry weight of roots per plant. However significant reduction was obtained in stems length and relative water content in water-stressed in plant. Moreover, morphological variations were particularly evident in stressed plants especially in the number of stems, leaves, flowers and pods number.
