Plants regulate metabolism under the effect of gravity, which affects growth direction, morphogenesis and biochemistry by changing the metabolic pathways. In present study, the effect of microgravity stimulation on biogenic elements and growth profiles of rice, wheat, barley, pea and grass during early growth stages was investigated. Clinostat was used for gravity stimulation, which was applied at embryonic stage. Seeds were grown under laboratory conditions at 24±2 ºC and 3 days-old seedlings were exposed to the microgravity generated by clinostat rotation at 40 rpm for 96 h and 90 rpm for 70…mehr

Plants regulate metabolism under the effect of gravity, which affects growth direction, morphogenesis and biochemistry by changing the metabolic pathways. In present study, the effect of microgravity stimulation on biogenic elements and growth profiles of rice, wheat, barley, pea and grass during early growth stages was investigated. Clinostat was used for gravity stimulation, which was applied at embryonic stage. Seeds were grown under laboratory conditions at 24±2 ºC and 3 days-old seedlings were exposed to the microgravity generated by clinostat rotation at 40 rpm for 96 h and 90 rpm for 70 h and. The biogenic elements and growth parameters were measured. The seedling fresh and dry weights recorded to be higher under gravity stimulation at 40 rpm for 96 h clinostat rotation. The micro- and macro-nutrient were also enhanced under same set up. The seedlings exposed at for 70 h at 90 rpm did not affect both minerals and growth parameters, which revealed that microgravity has variable and stimulatory effect on plant characteristics under specific conditions.
