Screening of waterlogged resistant maize varieties by determining root porosity.

Abstract

In the present laboratory and field investigations we sought to ascertain the effect of water logging on root porosity maize var Suwan and Ganga Safed-2; 11-days maize seedlings under the laboratory was treated with 2, 3 and 4 days of water logging followed by 2-days recovery whereas in the field condition, treatment of 4, 5 and 6 days of water logging followed by 2-days recovery was treated in 28- and 63-days of maizeplant under both laboratory and field situations. It was observed that the porosity of root followed a decreasing trend with the increase in duration of water logging. However, 2-day recovery period improved leaf porosity following an increasing trend over their respective treatments of water logging in both the varieties, more in Suwan than Ganga Safed-2.
