New Zealand Journal of Agricultural Research, 13(4), 869-877. doi:10.1080/00288233.1970.104305190028-8233https://hdl.handle.net/10182/10957Single plants of Arawa and Hilgendorf 61 wheat growing in pots were exposed to soil moisture stress at different stages of development. Plants treated when the apical meristem had reached the double-ridge stage had fewer spikelets than plants treated later, but the greatest effect on grain yield occurred through reduction of grain number in plants subjected to dry conditions from the time of spikelet formation. Single grain weight was most affected by moisture stress imposed at ear emergence. Treatment after anthesis reduced single grain weight in Arawa but not in Hilgendorf 61. Plant height was reduced most if water shortage occurred before ear emergence.869-877en© Crown Copyright 1970New Zealand wheat varietiessoil moisturestressdevelopmentJournal ArticleANZSRC::070302 AgronomyANZSRC::0701 Agriculture, Land and Farm Management
