The field performance of induced uniculm grain sorghum sorghum bicolor in south east queensland australia

Experimental Agriculture 22(4): 393-404

The field performance of induced uniculm grain sorghum sorghum bicolor in south east queensland australia

Reduction of leaf area in sorghum without tillers (uniculm sorghum) might result in conservation of water at early stages of growth and hence in stability of grain yield under dry conditions. In two experiments in south-east Queensland, Australia, tillers were removed by hand to examine the growth of uniculm sorghum. Tiller removal promoted root development at the flag leaf stage but significantly reduced shoot dry matter and lowered grain yield by about 20% in a wet season. The saving in soil water as a result of tiller removal was relatively small but statistically significant.

Camargo, C.P.; Vaughan, C.E., 1973: Effect of seed vigor on field performance and yield of grain sorghum (Sorghum bicolor (L) Moench). Hybrid grain sorghum seeds were aged for 0, 3, 5, 7 or 11 days at 42 deg C and 100% r.h. In a laboratory experiment, percentage germination decreased only in seed aged for 5-11 days. Aging progressively reduced shoot and root length in 4-day old s...
