Other claims from this paper (8)
- Intervention effect Moderate salt stress caused substantial losses in the number of wheat tillers.
- Intervention effect Grain yields of the main stem and tillers Tl and T2 under moderate salt stress were as great or greater than in nonstressed plants.
- Intervention effect The main stem contribution to yield on a land area basis rose from about 25 to 35% in nonsaline treatments to over 80% with increasing salinity.
- Intervention effect Primary tiller contribution to yield decreased substantially only at the highest salinity levels.
- Intervention effect Number of kernels per spike increased or was unaffected under salinity, except at the highest stress level.
- Intervention effect Increasing salinity decreased total straw yields primarily because of fewer tillers.
- Intervention effect Increasing salinity made dry weights of the main stems and remaining tillers smaller.
- Mechanism Loss of spike-bearing tillers accounts for most of the yield reduction in salt-stressed wheat.
