Match List-I (Plant Physiological Phenomena and Agricultural Technologies) with List-II (Biological Mechanisms and Agronomic Applications) and select the correct sequence of matching pairs:

  • GuttationExudation of liquid xylem sap droplets from leaf margins through hydathodes driven by positive root pressure under high humidity.
  • ApomixisAsexual formation of seeds without fertilization, enabling the fixation and preservation of hybrid vigor across crop generations.
  • ParthenocarpyDevelopment of seedless fruit structures without ovule fertilization, often induced by exogenous application of auxins or gibberellins.
  • MicropropagationIn vitro culture of totipotent tissue explants on synthetic media to rapidly produce large quantities of pathogen-free clones.

Cevap

Guttation pairs with liquid xylem sap exudation through hydathodes via root pressure; Apomixis pairs with asexual seed formation preserving hybrid vigor; Parthenocarpy pairs with seedless fruit development without fertilization; Micropropagation pairs with in vitro tissue culture producing disease-free clones.
Guttation corresponds to the exudation of xylem sap via hydathodes under positive root pressure. Apomixis represents asexual seed development without fertilization that preserves hybrid traits. Parthenocarpy corresponds to the formation of seedless fruits without ovule fertilization. Micropropagation refers to in vitro clonal propagation using tissue explants.

Adım Adım Çözüm

1
Analyze Guttation
Guttation is driven by positive root pressure during periods of low transpiration, causing sap loss through hydathodes.
Differentiates guttation from transpiration (gas phase water loss through stomata).
2
Analyze Apomixis
Apomixis yields asexual seed formation without syngamy.
Key biotechnological target for maintaining hybrid vigor in successive seed generations.
3
Analyze Parthenocarpy
Parthenocarpy leads to fruit development without seed formation.
Distinguishes seedless fruit development from parthenogenesis (embryo creation).
4
Analyze Micropropagation
Micropropagation relies on in vitro culture of tissue explants to generate elite clones.
Core technique in modern plant tissue culture and clean planting material production.
