HORT 2050 : Hort 2050 Exam 3
Document Summary
Plant physiology= functions and activities of living plants. When it"s hot they keep growing: cam, modified c4 for desert plants. Glucose formed during the day: rate of photosynthesis dependent on light quality and intensity, day length/photoperiod, co2 concentration, temp, water. Respiration= release of energy stored in carbs from photosynthesis for cell activity. C6h12o6 +6o2 +h2o -> ^co2 +12h2o+atp: glycolysis-> pyruvic acid->krebs w/ o2 and results in 36 atp, glycolysis-> pyruvic acid-> fermentation no o2 and results in 2. 16 essential elements: naturally occurring in atmosphere, c,h,o from water and respiration, needed in large quantities. Fertilizers: n,p,k,ca,mg,s, minute quantities, b,fe,mn,zn,cu,mo,cl, 6, ph changes nutrients form ph organic- compounds with c-h compounds, pro- improves soil structure, increases organic matter, con- slow, costly, application method inorganic- compounds w/o c-h . Ka used for osmotic, enzyme activiation, protein synthesis. Used for amino acids, enzyme activation, and synthesis of chlorophyll biological competitors. Ex) flire blight in rosaceae: fungi= saprophyte and parasites.
