Interactive Effect of Elevated CO2 and Moisture Stress on Anatomical Configuration in Brassica Species

Ranjan Das · International Journal of Environment and Climate Change · 2021

Free-Air CO2 Enrichment (FACE) was developed as a means to study the crops response to elevated level of CO2 under the fully open-air field conditions. In this study, results of FACE experiments are summarized by disusing the root and shoot anatomy. Result indicated that elevated...

Interactive Effect of Elevated CO2 and Drought Stress on Leaf Anatomy in Brassica Species

Ranjan Das · International Journal of Environment and Climate Change · 2021

The aim of present study was to understand how the ultrastructure of the leaf mesophyll cells in Brassica leaf can be altered under elevated CO2 by interactive effect of elevated CO2 on leaf anatomy and ultra structure of Brassica species under moisture stress conditions. Results...

Red Edge Position (REP), an Indicator for Crop Stress Detection: Implication on Rice (Oryza sativa L)

Jonali Goswami, Ranjan Das, K. K. Sarma & P. L. N. Raju · International Journal of Environment and Climate Change · 2021

Crop stresses due to both biotic and abiotic are the major factors affecting crop productivity. The need of the hour is to minimize the yield losses due to these stresses. Early detection can help to reduce the impact of stresses on crop growth and yield. Remote sensing technique...
