This book was released on 1980 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was undertaken to better understand plant characteristics related to high and low forage yield in tall fescue selections as affected by temperature. Dry matter distribution into yield components in three different temperature regimes was evaluated. Root growth, dark respiration and nutrient concentration were also examined. The four diverse tall fescue selections grown under controlled environmental conditions exhibited yields similar to those noted in the field. Selection TFM 26 produced more forage yield at the low temperature while TFK 12 produced more at the high temperature indicating a seasonal growth response. However, TFM 26 was the highest yielding selection when averaged over the three temperature regimes. High yielding TFM 26 had the greatest leaf area and low yielding TFK 4 the least. Higher yielding TFM 26 and TFK 12 had more leaf area per tiller than the other selections and TFM 26 had the greatest number of tillers. Root volume had a closer association with forage yield than root dry matter (RDM). Winter-growing TFMs had greater RDM than the summer-growing TFKs. Root density was higher for winter-growing TFM 16 which appeared to be partitioning more root dry matter into root 'bulk' than root volume. Winter-growing TFMs had higher root-to- shoot ratios than TFKs suggesting that winter-growing selections distribute their dry matter differently. Growth analysis showed that relative growth rates were higher for high yielding selections. High yielding selections also had a higher relative leaf area growth rate (RLAGR). A rapid leaf area development may be producing more available photosynthate at an earlier growth stage giving high yielding selections their yield advantage. The relative root growth rate (RRGR) was greater for winter-growing TFMs than for TFKs. The high RRGR of TRM 26 may be related to its high RLAGR. The harvest index was higher for summer-growing TFKs than winter-growing TFMs. Dark respiration rates in roots and leaves did not differ throughout the experiment. Mineral analysis showed that K accumulation per unit of root volume was greater for winter-growing TFM 16 than TFM 26, however, TFM 26 had greater K per gram of root material. The data suggest that winter-growing TFM 16 may absorb and translocate more K than TFM 26. Summer-growing TFK 12 had low Mg at the low temperatures suggesting that animal consumption may induce a Mg deficiency (grass tetany) when grazed during low temperatures.

This book was released on 1982 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field study with 5 tall fescue genotypes treated at the vegetative growth stage, with 0, 0.28, 0.56, and 0.84 kg/ha of mefluidide was initiated in July, 1980. The regrowth of these plants were again treated at the booting growth stage in April, 1981, with the same rates of mefluidide as in the first experiment. In addition, three rates of mefluidide (0, 0.28, and 0.56 kg/ha) were applied at the floral initiation stage of perennial ryegrass cv. Linn in March, 1981. Four varieties of tall fescue were transplanted from the field into 6-inch pots in February, 1981, and grown under 50/60°F and 70/80°F night/day temperature regimes in growth chambers. Mefluidide at the rate of 0, 0.28, and 0.56 kg/ha were applied at the pre-floral or at floral initiation growth stage. The same varieties were again transplanted from the field into 6-inch pots in April, 1981, and grown under the same temperature regimes and treated at pre-booting or at booting growth stage with the same rate of mefluidide as those in the first growth chamber experiment. Mefluidide interacted with tall fescue genotypes and also resulted in a reduction in dry matter yield, ADF (Acid Detergent Fiber) and increased CP (Crude Protein) content in both tall fescue trials in the field. The WSC (Water Soluble Carbohydrate) concentration was reduced by mefluidide applied at the vegetative growth stage in the first experiment, but it was increased at the booting growth stage application of mefludide on regrowth of these plants. Late applications of mefluidide did maintain forage quality of tall fescue with some elimination of dry matter yield reduction caused by earlier application. In perennial ryegrass cv. Linn, mefluidide reduced stem dry matter production, but did not affect leaf dry matter yield. This was accompanied by high leaf/stem ratios and retardation of plant height. Fertile tiller production was inhibited, accompanied by reduction in ADF, increased stem CP and increased WSC of leaf and stem tissue. Under the 70/80°F night/day temperature regime, all varieties produced a higher dry matter yield than plants under a 50/60°F night/ day temperature regime. However, WSC content of leaf and stem were higher in the low temperature regime. There were indications that mefluidide reduced ADF and WSC content of leaf and stem tissues, but increased leaf and stem CP under both temperature regimes in both experiments. This was accompanied by high leaf/stem ratios of treated plants.
