ABSTRACT
An experiment was conducted to find out “ Biochemical basis of lodging nature of rice in rice (Oryza sativa L.)” by studying relevant parameters in three different groups of rice germplasm viz., lodging susceptible varieties (Swarna, BPT-5204, Tellahamsa and RNR-15048); lodging tolerant varieties (MTU-1112, MTU-1121, MTU-1166 and MTU-1001); and stable strong culm mutant lines (SP-351, SP-353, SP-360 and SP-70). Biochemical analysis showed that mineral components are strongly correlated to the physical strength of rice culms in other words, lodging nature. It should be noted that N and Si content of culms decreased between 50% flowering and full ripening stages of rice, while K increased. At 50% flowering stage, N content of culms significantly correlated to physical strength of culms, while at full ripening stage showed non-significant correlation. However, K and Si contents of culms showed highly significant correlation with physical strength of culms i.e., lodging tolerance.
Keywords: Total nitrogen content, Total potassium content, Total silicon content.
