2016- Physiology BISA

Overview

Physiology Trial at BISA, Ludhiana conducted in 2015-16. The idea is to study the photosynthetic patterns of high and low yielding lines where the lines do not differ much agronomically. A total of 21 genotypes including 7 international checks in two replications are planted. Three different showing dates are available for all 7 checks.

Protocols

The One Protocol (Phi2, PSI, NPQ) II

The One Protocol to rule them all! Phi2, PSI, NPQt, combined!

Changes from previous The One protocol: - no longer outputs signal from the far red period, which simplifies the signal output for the user - changed distance between measuring pulses from 10,000 to 2,000 which improves measurement resolution - has an initial stabilization peri...

Chlorophyll content (SPAD) I

REQUIREMENTS: Firmware v0.38 or lower (used for older devices which do not have a SPAD calibration, generally device ID 87 and lower).Measures transmission at 940nm and 650nm in order to determine the 'greenness' of a leaf, an indicator of chlorophyll content and nitrogen content. The 940 is used to account for leaf thickness.

Proton Motive Force via DIRK

Estimates the proton motive force through the ATP synthase, thereby estimating ATP production. The proton motive force is measured by measuring the electrochromic shift (ECS), the shift in the absorbance of chlorophyll at ~520nm in the thylakoid membrane due to a shift in the electric field. The electric field is created by the accumulation of...
