Seed Soaking As A Pre-Sowing, Drought-Hardening Treatment in Wheat and Barley Seedlings¹

The effect of seed soaking treatment of winter wheat (Triticum aestivum L.) was investigated using distilled water or nine other dilute solutions — CaCl₂, ZnSO₄, Fe₂(SO₄)₃, adenine, gibberellic acid, vitamin K₃, 2,4-D, and garlic extract. Three wheat varieties and two barley (Hordeum vulgare L.) varieties were also subjected to seed pre-sowing treatment hi water or 0.25% CaCl₂ solution.

The seedlings were tested at 3 to 4 weeks of age for desiccation resistance, transpiration, germination and growth in mannitol, and recovery. CaCl₂ solution, 0.25%, seemed to be somewhat effective in inducing more desiccation resistance in wheat, with the ‘Ponca’ variety showing the highest response and ‘Red Chief’ the lowest. In barley, water or CaCL₂ induced better water retention in ‘Ward’ variety only. No response was detected in ‘Rogers.’ Seed pre-soaking in 2,4-D caused a decrease in desirable xeromorphic features. Most of the other treatments had either no effect or undesirable effects.

It is concluded that no generalized statement as to the effect of pre-sowing seed treatment can be made since the response seems to depend upon the treatment and variety used. This may help to explain some of the contradictory results reported in the literature.
