Some Observations on the Selection of Single Stools at Mount Edgecombe
نویسنده
چکیده
The performance of approximately 300 original seedlings was compared in the single stool stage of the selection programme with their performance at the next stage (single lines). The apparent gain from selection in single stools was compared with respect to various methods of selection and different operators. The performance of unselected and selected seedlings ' was measured in the single line stage, and determinations of the real gain from the single stool selections were made. In the particular batch of single stools studied, using the standard selection procedure, a real gain from selection of 21,6% was achieved in mass cane. The degree of genetic determination for cane yield was 0,4.

Introduction: Blastocystis hominis is a parasite found in the stools of human as well as in the stools of other animals and recently its pathogenic potential has been increasingly recognized. Irritable Bowel Syndrome (IBS) is a digestive system’s disorder which is featured by change in bowel habits, abdominal pains and other symptoms similar to Blastocystis hominis infection. There is lit...
متن کاملChanges in Soil Fertility Induced by Trash Reten- Tion and Fertiliser Applications on the Long-term Trash Management Trial at Mount Edgecombe
The long-term effects of green cane harvesting with trash retention, compared with burning, on soil fertility were evaluated using data from the long-term trash management trial at Mount Edgecombe (BT 1). Total and potentially mineralisable soil N were greater under green cane harvesting than burning in the surface 0-10cm layer of soil. As expected, fertiliser applications induced increases in ...

A combined hydraulic engine mount and buffer is proposed in this study for use in the mid-priced vehicle. In some vehicle design projects, an engine is selected to use in a new car design. To achieve the desired vibration conditions, the mount can be redesigned with exorbitant costs and long-term research. The idea of using a buffer in the combination of the conventional engine mount is to sugg...
