| Summary: | 6:6, 3:9, and 0:12 in 19 1 pots. Controls were well watered and the prolonged drought of the companion experiment than in around in control mixtures than ryegrass. Wheat maintained a companion experiment used rhizotron columns to compare the competitive with wheat in almost all measures. Ryegrass was controls. However, the ryegrass in mixtures regrew culture than the mixtures and greater in the well watered drought mixtures. There was no alleopathic interaction. A drought. Above-ground growth of wheat was greater in pure equally competitive with wheat for root growth in control and for the 14 wk experiment. Plants exposed to drought were greater in both the temporary drought of the main experiment greater in the drought than the well watered treatment. greater leaf expansion rate and area during drought than Greenhouse experiments compared the growth of wheat and growth than wheat in pure cultures. But, the greater seed interaction 7 wk after transplanting seedlings of wheat and mixture than the drought mixture. The proportion of ryegrass produced by 14 wk after planting more above and below-ground replacement series with wheat:ryegrass ratios of 12:0, 9:3, ryegrass during continuous well watering and prolonged ryegrass in pure culture and mixtures in response to ryegrass. Drought and rewatering enhanced the growth of size and height allowed wheat to be more competitive above- temporary and prolonged droughts. The main experiment was a Thus, the competitiveness of ryegrass relative to wheat was to wheat as a percent total growth in these mixtures was vigorously during 4 wk of rewatering and was equally well watered conditions. well watered for 4 wk. Despite a much smaller seed than well watered for 8 wk, had no water for 2 wk, and then were wheat and a similar time of emergence, control ryegrass wheat relative to ryegrass in pure culture compared to |
