| Abstract/Contents: | "Nitrate uptake efficiency of turfgrass has been a means of predicting relative nitrate losses. This study determined cultivar and individual differences in nitrate uptake rate and investigated the relationship of nitrate uptake between creeping bentgrass (Agrostis palustris Huds.) seedlings and mature plants. A better understanding of this relationship and the differences among and within cultivars would allow for selection of individuals and populations with higher nitrate uptake rates at the seedling stage, thus hastening the selection process. In this study, we measured nitrate uptake rates of 19-d-old individual seedlings and 4-mo-old mature plants of cultivars Bar As 490, Crenshaw, L-93, Penneagle, Providence, and Seaside II. Seedlings were clipped to 1.3 cm for the final 4 d of an 18-d uptake period. These seedlings were then planted in sand and maintained as turf. After 4 mo, the plants were excavated, roots were washed to remove sand, and nitrate uptake was measured for 7 d. These plants were clipped to 1.3 on day 5. Significant differences in nitrate uptake rate expressed on a per-plant, root length, or root mass basis were observed among or within cultivars at both stages. Low correlation was found between nitrate uptake at the seedling stage and mature turf stage in all six cultivars used. Correlation was greatest when post-clipping rates of seedlings and mature turf were compared." |
