| Description | Termoinhibering van Lactuca sativa L. cv. Great Lakes 659-saad het by 36 °C voorgekom. Termoïnhibering is deur 'n kombinasie van 100% en kinetien (10 mg dm⁻³) opgehef. Chlooramfenikol het die voordelige invloed van plus kinetien opgehef. Verskeie mitochondrionaktiwiteite (respirasie, koppeling, sekere matriksensiemaktiwiteite en inkorporering van [³⁵S]-metionien in mitochondrionproteiene) was by termogeïnhibeerde saad laer as by saad wat by 25 °C gembibe er is. Behandeling met suurstof plus kinetien het veroorsaak dat hierdie aktiwiteite by 36 °C geïmbibeerde saad tot dieselfde, of hoër vlakke plaasgevind het as by 25°C-kontrolesaad. Thermoinhibition of Lactuca sativa L.cv. Great Lakes 659 seeds occurred at 36 ˚C. Thermoinhibition was alleviated by a combination of 100% O₂ and kinetin (10 mg dm⁻³). Chloramphenicol nullified the effect of O₂ plus kinetin. A number of mitochondrial activities (respiration, coupling, certain matrix enzyme activities and incorporation of [³⁵S]- methionine in mitochondrial proteins) were lower in thermoinhibited than in seeds imbibed at 25 ˚C. Treating seeds with plus kinetin at 36 °C restored these mitochondrial activities to the same or in some cases, to higher levels than in 25 °C control seeds. | |
