Abstract
This study was conducted to investigate the effect of differential saline levels on the growth and development of nine Pearl millet accessions (Pennisetum glaucum). The experiment was conducted at the research station of the Faculty of Agriculture, An Najah University, Tulkarm, Palestine. The seeds were planted on 4th of April 2016; seeds of the nine accessions were planted in plastic containers filled with sandy soil. Five plants were placed in each container. The plants were irrigated with three salinity levels (fresh water as a control, 75 mM , 150 mM NaCl), with three replicates for each treatment. The results demonstrated that germination percentages, radical and coleoptile length were significantly affected by increasing salinity level. Highest germination percentages at 0 salinity level (control) were observed in accessions IP 6104.
The germination percentage for all accession decreased significantly for 100 mM , 150 mM and 200 mM except IP 6104 accession . in the high level 250 mM the germination percentage decreased significantly, the highest germination percentage IP 19612 accession. the lowest germination percentage was recorded with Sudan pop III, Sudan pop I, ICMS 7704, MC 94 C2 and ICMV 155 accessions.
Shoot length was found to be significantly reduced when salinity level was increased. However, the average tillers number was not affected by salinity. And significant differences were observed among accessions on shoot length and tillers number.
Chlorophyll content was found to be significantly affected by salinity. were the chlorophyll content decrease when salinity level increase.
No significantly different was conducted between accessions. the nine accessions exhibited statistically different root fresh and dry weight and shoot fresh weight but shoot dry weight not affected significantly . Ash content decrease significantly per salinity treatment and at all accessions Ash content was differ.
Neutral detergent fiber (NDF) content of the different accession was not significantly affected with salinity treatment.
In conclusion, the present study demonstrated the ability of pearl millet to grow under saline condition. As such, indicating that this forage crop has a good potential for planting in areas with high soil salinity. Additionally, cluster analysis show that the MC 94 C2 accession provided the best results in germination and field experimentation.
