A light response curve can provide indications of the:
• Dark respiration rate: The photosynthesis rate with no light,
• Light compensation point: Absorbed quantum flux for which photosynthesis and respiration are balanced
• Quantum efficiency: Initial slope of the assimilation rate, and
• Light saturated photosynthetic rate (Asat).

00:00 Recap attending light course fortnight back (https://www.youtube.com/watch?v=ORpE4y4ZuVg)
03:40 Basic Making Graphs for Light Curves
04:00 The components of  abscissa and ordinate  x-y axes 
09:33 The number, letter and F menus in LI6400XT
10:00 Plotting light curve from data points
10:40 Biphasic nature of light curve
11:20 Information can be derived from light curve
11:39 Light curve indicates Dark Respiration rate
11:58 Light curves indicates Light Compensation Point LCP
14:50 Light curves indicates Quantum Efficiency
17:25 Light curves indicates Maximum Photosynthetic Rate Amax Assimilation
18:23 Photoinhibition due to excess light
19:30 Light curves tells if plant more towards shade type or sun type
25:55 Know the reason behind actions. Don't entertain crazy clueless supervisor
31:30 Setting up environments in LICOR 6400XT and LI6800  chamber to acclimate leaf
39:00 To choose leaf: Determine the plant phyllotaxy ( leaf arrangement)
40:00 Choose fully expanded leaf, level 3 to 5 from the top like in Choy Sum
40:21 Don't count leaf bud or primordia as a leaf count
43:10 Don't use broken leaf
45:20 Choosing leaf of palmate morphology like Okra
56:40 Sings of acclimated leaf in the chamber. Ensure this before run Light Curve
1:04:26 Adding water to Stuttgarter Masse column in LI6800
1:06:15 Press square bracket ] on LI6400 to see current graphs to determine acclimation level of the clamped leaf
1:32:57 Extra - Intro to do A/Ci Curves CO2 response Curve
1:45:40 Why CO2 concentration set for CO2 curve not similar like light curve.
