🔰Aminisation: Hydrolytic decomposition of proteins results in the release of amines and amino acids. 🔰Ammonification: The amines and amino acids released are coverted to ammonium compounds. 🔰Nitrification : Biological oxidation of ammonium ions to NO3 is known as nitrification. 🔰Aminisation, ammonification – Heterotropic bacteria. 🔰Nitrification – autotrophic bacteria 🔰NH4 to NO2- - Nitrosomonas, nitrococcus 🔰NO2 to NO3- Nitro bacter. 🔰The nitrosomonas, nitrobacter are usually refered to as the “nitrobacteria”. 🔰High C:N ratio prevents the release of ammonia. If the ammonia is present in too high conentration, it constrains the nitrification. 🔰Nitrification will be appreciable at filed capacity of soil moisture content and takes place even at (or) below the wilting coefficient. 🔰Nitrification takes place at a pH 5.5 to 10.

Hybrid Culture 🔹 Callus – A tissue arising from disorganized proliferation of cells. 🔹 Subculture – A septic transfer of a part of a culture to fresh medium. 🔹 Passage time - The time interval between two successive sub cultures. 🔹 Suspension culture – Cells (or) cell aggregates culture in liquid medium. 🔹Batch culture – Cell suspension grown in a fixed volume of liquid medium. 🔹 Explant – A plant organ (or) piece of tissue used to initiate culture. 🔹Excise – To remove a piece of tissue (or) an organ from its parent source. 🔹 Meristemoid – Cluster of meristematic cells with in Mcallus with a potential to form primordia. 🔹Embryoid – Non zygote embryo formed in culture. 🔹 In vitro – “In glass” 🔹 In vivo – “In life”. 🔹 Parasexual hybridization (or) somatic hybridization – Hybridisation by non sexual methods. Eg: Potoplast fusion. 🔹Heterokaryon – A cell in which 2 (or) more nuclei of unlike genetic make up are present. 🔹Synkaryon – Hybrid cell produced by the fusion of nuclei in homokaryon.

🌳Apomixis: -It is a form of asexual reproduction in which seed is produced but the embryo develop without fusion of male and female garnets. 🌳When sexual reproduction occurs besides apomixes, the apomixes is termed as "Facultative apomixes". 🌳Apospory-Some vegetative cells of the ovule develop into unreduced embryo seed without meiosis. 🌳Apogamy-Synergids (or) antipodal cells develop into embryo. 🌳Pseudogamy-Development of apomictic seed by the stimulus of pollination and pollen tube growth without fertilization. 🌳Parthenogenesis-Development of a embryo without fertilization. 🌳Parthenocarpy-Development of fruit without seed. 🌳Monogamy-Both male and female flowers mature at the same time. 🌳Chasmogany-Flowers open only after pollination. 🌳Dichogamy-Male and female flowers mature at different times. 🌳Heterostyly-Flowers are bisexual but stamens and styles are of different lengths. 🌳 In often cross pollinated crops cross pollination exceeds 5% Join🔜 AgriYuvaa
