Water activation system using granular ceramics and its effects on plants growth (part 2)-application of treated water for seed vernalization

摘要

In order to apply wheat (Triticum vulgare VILL.) seeds of winter habit to the late-summer sowing culture, the vernalization treatment method was carried out using water treated with ceramics.The plant height and the growing speed were promoted with the low temperature treatment using water treated with ceramics instead of tap water, and the maximum tillering stage was faster than that using tap water in the pot test. On the other hand, in the field test, the tiller was promoted, and the number of stems increased with low temperature treatment using water treated with ceramics instead of tap water. The heading period was accelerated by performing low temperature treatment using water on seeds. However, the difference of the heading date between the low temperature treatment using tap water and the low temperature treatment using water treated with ceramics was 2～3 days.The effect of treated water with ceramics on the yield component was observed to be greater than the control and treatment using tap water in the pot test, however, the difference of the yield of the treatment using water treated with ceramics and other treatments was not clear in the field test.
