Principle of photometer -> absorption = transpiration.
Diffusive cap = amount of difference from stmata.
Amount of difference from free water surface.
Antitranspirant – ABA, Co₂, PMA, dodecenyl succinic acid, C₂H₅oH, silion boys low viscidity bags.
Saturation deficit = water vap to saturate air – absolute humidity.
Relative humidity = X 100
Transpiration rate light temp loing ratio.
Transpiration only aevial surface is a necessary evil blcause to life plant has to do photosynthesis & keep stomata open & maintain a film of water on the mesophyte cells to dissolve incoming Co₂.
Clayey soil needs more irrigation for growth.
Afternoon tramsp > Forenoon.
Tramsp – High altitude > Lower.
Trans > absorp – Temporary wilting.
Lack of water – Permament wilting.

Genetics

Normal Punnet & Bateson. Phenol – 9: 3 : 3 : 1, Geno – 1 : 2 : 1 : 4 : 2 : 4 : 12 :1
Complementary both genes eqreally 9 : 7 CR – Red, CR – White, Cr – White, cr – white, Lathyrus odoratus by Batsen & Punnet.
