Competitive Exams: Revision Terminology Part 55

  • 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 = AbHumiditywatervap X 100

  • Transpiration α rootshoot rate α light α temp α loing α areavol 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 α temp α 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.
