Populations from Seeds Collected from Different Locations}, journal={Türkiye Tarımsal Araştırmalar Dergisi}, volume={3}, pages={30–36}, year={2016}, DOI={10.19159/tutad.50527}, author={Dönmez, Hasan Beytullah and Uzun, Ferat}, abstract={<p>To investigate the effect of seed origin on the nutritive value of narrowleaf birdsfoot trefoil (NBT, Lotus tenuis <br />Waldst.&Kit.), seeds of 86 NBT populations were collected from plants spontaneously occurring in natural pastures and <br />rangelands located at different geographical gradients of the Black Sea Region, Turkey. Some nutrient contents of these <br />populations regrown under the same conditions were determined. Minimum and maximum values with regard to the crude <br />protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), Ca, P, Mg, K and condensed tannin contents, <br />relative feed value, Ca P-1 and K (Ca+Mg)-1 ratios were found as 176.83 and 238.87, 201.00 and 351.61, 307.19 and <br />435.48, 15.01 and 21.60, 2.18 and 3.77, 3.03 and 4.02, 8.43 and 16.69, 20.00 and 31.50 g kg-1 dry matter, 189.70 and <br />263.41, 4.73 and 9.57, 0.35 and 0.88, respectively. The effects of seed genotype from different altitudes (Ca P-1), latitudes <br />(digestible dry matter and ADF) and longitudes (CP and Mg) on some nutrient contents and feed values were found <br />significant (P<0.05). The correlations between altitude and NDF, P and Mg or between latitude and P and Mg contents of <br />populations were significant. There were no specific trends in chemical composition and the nutritive value of tested NBT <br />populations due to geographical variation. Thus, the results suggested that all studied geographical populations can be <br />selected to obtain the nutritionally superior forage. </p>}, number={1}, publisher={Siirt University}
