“…Carbon dioxide (CO 2 ) is one of the main greenhouse gases. The level of CO 2 keeps increasing and subsequently causes a series of environmental problems, especially for agricultural crops[ 31 , 32 ]. In the present study, we investigated the effects of TiO 2 NPs on wheat seedlings cultivated under super-elevated CO 2 conditions (5000 mg/L CO 2 ) and under normal CO 2 conditions (400 mg/L CO 2 ).…”

Concerns over the potential risks of nanomaterials to ecosystem have been raised, as it is highly possible that nanomaterials could be released to the environment and result in adverse effects on living organisms. Carbon dioxide (CO2) is one of the main greenhouse gases. The level of CO2 keeps increasing and subsequently causes a series of environmental problems, especially for agricultural crops. In the present study, we investigated the effects of TiO2 NPs on wheat seedlings cultivated under super-elevated CO2 conditions (5000 mg/L CO2) and under normal CO2 conditions (400 mg/L CO2). Compared to the normal CO2 condition, wheat grown under the elevated CO2 condition showed increases of root biomass and large numbers of lateral roots. Under both CO2 cultivation conditions, the abscisic acid (ABA) content in wheat seedlings increased with increasing concentrations of TiO2 NPs. The indolepropioponic acid (IPA) and jasmonic acid (JA) content notably decreased in plants grown under super-elevated CO2 conditions, while the JA content increased with increasing concentrations of TiO2 NPs. Ti accumulation showed a dose-response manner in both wheat shoots and roots as TiO2 NPs concentrations increased. Additionally, the presence of elevated CO2 significantly promoted Ti accumulation and translocation in wheat treated with certain concentrations of TiO2 NPs. This study will be of benefit to the understanding of the joint effects and physiological mechanism of high-CO2 and nanoparticle to terrestrial plants.

“…Leaf area is positively correlated with stomata opening, the number of tillers and plant height. If osmotic regulation occurs, the plant can maintain its turgor pressure and stomata conductance [14]. It increases photosynthetic activity so that many photosynthates are distributed for cell enlargement [12].…”

Climate change is indicated by extreme weather changes, namely drought on agricultural land, thus limiting crop growth. The availability of rice as a food source in developing countries has not met the increasing food needs of the population. The low planting area and productivity, which are said to be the triggers for the problem, can be overcome by nutrient management on dry land. Iron serves a function in the physiology and metabolism of plants. Iron sprayed on the leaves in the form of nano Fe2O3 can increase the efficiency of nutrient absorption by plants. This study aims to evaluate the effect of the application of nano Fe concentration on rice growth in drought-stress conditions. The study was conducted in the Sleman experimental field using the Split Plot Design method with two factors (water content of 100; 50% and nano-Fe concentration of 0; 0.5; 1; 1.5; 2 ppm). Based on the results of the study showed that there was an independent effect of treatment on growth. Spraying nano Fe 0.5-1 and 1.5-2 ppm reduced membrane damage by 3.27% and 8.25% respectively, and there was a negative correlation between membrane damage and growth parameters.
