ABSTRACT
The present study entitled “study of the histological basis for lodging tolerance in rice (Oryza sativa L.)” was conducted to find out histological basis of lodging nature of rice 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). Histological studies revealed that in rice physical strength of the culm was highly correlated to the number of vascular bundles of cross sectional area of the basal culm (3rd internode) as well as the thickness of dermal sclerenchyma. It should be noted that pattern of distribution of vascular bundles didn’t differ in the varieties / lines under the present study. Therefore, if time and facilities permits, these two histological parameters should be considered while measuring lodging nature of rice culms.
Key words: Number of vascular bundles, distribution pattern of vascular bundles and thickness of epi /hypodermal lignified tissues in rice culm.
