  • 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.
  • Supplementary A – ivory, B – magneta, 9: 3: 4, Snapdragon (Antirrhinum) .
  • Inhibitory (B) inhibit (A) dominant suppressive recessive, 13: 3, Pigmentation in Rice – Green & purple.
  • Additive B = x A = x AB = 2x, 9: 6: 1, Pericarp colour of wheat – deep red/colourlac
  • Duplicative A = x B = x AB = x, 15: 1, Sherard՚s purse by shell.
  • Epistatis A (epi) ⇾ B (Hypo) , dominant <- A ⇾ white 12: 3: 1 gab -- ⇾ yellow. Gabb ⇾ green. Summer squash cucurbita pepo.
  • Plant devoid of root – ceratophyllum, wolffia, myriophyllum, utricularia, epipogium.
  • Plant devoid of stern – streptocarpus.
  • Plant devoid Branches – plams
  • Thalloid Angiosperm – Podostenon.
  • Contractile roots – crocus, canna, Lilium.
  • Stem

(1) caudex palm

(2) cudm Bamboo

(3) Scape onion

  • Emergent Hydrophytes –

Tropa.

Limnophilla

Hydriophyllun

Rananculus aquatilis.

Rananculus multifidus.

  • Root pocket – Pistia.
  • Multiple root cap – Pandanus.
  • Aim ab of light Dicot – weak & elongated stem, hook unopen, different X.
  • Monocot – excess elongation of 1st interuodo, more leaf develop.
  • Growth temp 1/light.
  • Photoblastic – lettuce seeds.
  • Internode elongation increment in absence of light.
  • Growth coeff – amount of growth per unit mass per unit.
  • Gram of nutrient consumed per unit time of individual.
