Agriculture One Liner Question

Agriculture One Liner Question

• A resource out of place – “Pollutant”.

• Allelopathic agent identified in Sorghum – Chlorogenic acid.

• Methane gas is mainly released from – Rice fields.

Agriculture One Liner Question

• World’s largest carbonate deposit were discouvered at “Mississipi”.

• Artificial rainfall – AgI.

• The transpiration/assimilation ratio is higher in C3 plants.

• Amino acid increases under water defiet – Proline.

• In case of grasses and fodder LAI – 6 – 11.

• Succinic acid for drought hardening in tomato.

• Plant that absorb dew very efficiently – Horse gram.

• Kaolinite – Reflective type of antitranspirant.

• Controlled burning to burn humus in acid soils.

Agriculture One Liner Question

• Allelochemical “Parthenin” present in leaves of parthinum Sps.

• Example of plant that converts from C3 to C4 photosynthesis is Rice.

• In monocotyledon is referred as “Seutellum”.

• Embryo and embryonic axis are the life of a new plant.

• Shoot of the cotyledon – Coleoptile.

• Base of the hypocotyls – Coleothiza.

• Nuclear endosperm – free nuclei – Eg: Wheat.

• Primary dormancy – Innate dormancy.

• Secondary dormancy – Induced dormancy.

Agriculture One Liner Question

• Failure of germination of mustard seed exposed to high concentration of CO2.

• Immature embryo –
Physiological dormancy. Eg: Apple, Pear.

• Breaking of dormancy with H2SO4 – Cotton.

• Senescence is ageing process.

• Heat stress – senescence interfere with Ca translocation.

• Antisenescence hormone – Cytokinins.

• Panicle senescence can be retarded by maintaining “Succinic dehydrogenase (SDH), ‘N’ application at booting stage.

• During senescence increase in activity of hydrolyzing enzymes.

• Downward movements takesplace in the sieve elements of phloem (Sugar).

• The process of sugar movement in the sieve tube – Translocation water and minerals – Xylem cells.

• The quantity of sugar translocated per unit cross sectional per unit time is called “Specific mass transfer”.

• Before reaching the sieve elements the sugars produced in green cells through layers of parenchyma cells. This process is called “phloem loading” or Vein loading.

The translocated sugars leaving the elements is known as “phloem unloading”. Both loading and unloading takes place in “Parechyma cells”.

Agriculture One Liner Question

• Auxins cause apical dominance – cell elongation.

Initial flowering in long day plants – GA.

• Bolting (Production of floral axis) – GA promote bolting – stem elongation GA shows inhibitory effect on germination of rice seeds,
