“…Similar results were tested and verified on ferns under Cu pollution (Zheng et al, 2008); Lolium, rice, and Sedum alfredii under Cd pollution Jia et al, 2010;Li et al, 2010Li et al, , 2012; as well as Lolium multiflorum and Phytolacca americana under combined Cd-Pb pollution (Song et al, 2013). In addition, EC improves the phytoremediation efficiency of heavy metals by enhancing root development, increasing fine root areas, and increasing heavy metal bioavailability in soil (Li et al, 2012;Song et al, 2013). Few studies have focused on the gas exchange and oxidative stress response of plants under heavy metal-contaminated soil to EC.…”

Our previous study has shown that EC increased biomass and total Cd uptake, but did not change the Cd concentration in the plant parts of poplar and willow species grown in Cd-contaminated soil (Wang et al, 2012).…”

“…At present, plants are simultaneously exposed to Cd-contaminated soil and EC as a result of the continuous deterioration of the environment and the increase in atmospheric carbon dioxide concentration. As such, an increasing number of researchers are devoting their attention to the combined effects of EC and heavy metal phytotoxicity on plants (Guo et al, , 2014Jia et al, 2010;Li et al, 2010Li et al, , 2012Li et al, , 2014Rajkumar et al, 2013;Song et al, 2013;Tang et al, 2003Tang et al, , 2011Zheng et al, 2008).

“…In some cases, elevated CO 2 can increase nutrient uptake more than the increase in shoot biomass leading to increased concentrations. Increases in shoot Fe concentrations have been reported in tomato (Jin et al 2009) and grasses (Duval et al 2012) and the concentrations of cadmium, Zn, manganese, and Mg increased in the shoots of the cadmium/zinc hyperaccumulator Sedum alfredii under elevated CO 2 (Li et al 2012). …”

Much of the recent gains in global crop production have been underpinned by greater use of fertilizer, especially nitrogen and phosphorus, and continued improvements in plant nutrition will be needed to meet the increasing demands for food and fiber from a growing world population. Climate change presents many challenges to improvements in nutrient use efficiency by its direct effects on the growth and yield of plants, and hence on nutrient demand, and by its influence on soil nutrient cycling, nutrient availability, and uptake. However, the consequences of climate change on plant nutrition are difficult to predict because of the complexity of the soil-plant-atmosphere system. Empirical data suggests that enhanced as well as reduced nutrient availability and uptake may occur as a result of climate change, depending on the nutrient in question and the component of the climate that changes. Notwithstanding the uncertainty of the effects of climate change on soil nutrient availability and plant nutrient uptake, improvements in nutrient use efficiency will be required to sustain productivity into the future.Over significant areas of the world's arable land, high inputs of nutrients have increased soil nutrient reserves and fertilizer use efficiency is low, while in other

“…In Egypt, the most important fiber crop is the cotton Gossypium barbadens (C3 plant) which have extra arid fibers which belongs to family Malvaceae and because of its economic importance, the phytophagous insect Spodoptera littoralis (Lepidoptera: Noctuidae) larvae is considered as a major and injurious pest of cotton in Egypt (Adham et al, 2005a, b). Thus, an important consideration here is that enriched CO 2 will generally increase the C allocations to roots in the cotton plant and the increase in root C will stimulate root growth (Rogers et al, 1992(Rogers et al, , 1994Li, 2012). In general, the growth response to enriched CO 2 is greater in C3 species than C4 species (Wand et al, 1999;Lee, 2011).…”

The effect of enriched CO 2 environments on natural plant-insect herbivore interactions is under attention. To understand such effects on insect growth and consumption, early and late instar larvae of the cotton leaf worm, Spodoptera littoralis (Lepidoptera: Noctuidae) reared on the cotton plant leaves Gossypium barbadens (Malvacae) grown under either ambient (350 PPM) or high (700 PPM) CO 2 atmospheres. Despite consuming more foliage, the mean larval fresh weight of the early (2nd) and late (4th) instar larvae increased insignificantly with age when fed cotton plant leaves from both ambient and enriched CO 2 regimes. Early and late Spodoptera littoralis larvae reared on high CO 2 -grown Gossypium barbadens consumed 32.87%, 44.98% respectively more foliage than larvae reared on low CO 2 -grown cotton plant. Larval duration for early and late larvae reared on high CO 2 -grown plants was longer compared with ambient treatments. The Consumption rate (CR) was decreased through the studied instars, with a high significant difference only between the 2nd instars. There was a tendency for ECI and ECD to decrease with age for larvae fed leaves from enriched CO 2 treatment. Differences in growth responses of early and late instar larvae to lower nitrogen and high-CO 2 grown foliage may be due to the inability of early instar larvae to efficiently process the increased flow of food through the gut caused by additional consumption of high CO 2 foliage. Under enriched CO 2 regime cotton plant shoot and root are significantly stimulate length, fresh and dry weights compared with ambient regime. С. А. Абу-Эльэля, В. М. Эльсаид. Влияние эффекта обогащенного СО 2 окуривания на взаимодействие растение-насекомое: питание и рост гусениц ранних и поздних возрастов египетской хлопковой совки Spodoptera littoralis (Lepidoptera: Noctuidae) // Дальневосточный энтомолог. 2018. N 351. С. 17-26.Резюме. Обсуждается влияние повышения концентрации углекислого газа на взаимодействие растений и растительноядных насекомых. Для этого гусеницы египетской хлопковой совки Spodoptera littoralis (Lepidoptera: Noctuidae) разводились на 17 листьях хлопчатника Gossypium barbadens (Malvacae), выращенных в атмосфере CO 2 при низком и высоком давлении (соответственно, 350 и 700 мм. рт. ст.). Гусеницы совки младших и старших возрастов потребляли листьев хлопчатника, выращенного при повышенной концентрации CO 2 , на 32.87% и 44.98% соответственно больше, по сравнению с выращенными при нормальном содержании углекислого газа растениями. Развитие гусениц младших и старших возрастов занимало больше времени при потреблении листьев растений, выращенных при повышенном содержании CO 2 . Норма потребления пищи (CR) уменьшалась у гусениц с возрастом, причем наиболее значительные различия отмечены у гусениц 2-го возраста. Отличия в росте гусениц ранних и поздних возрастов, питающихся выращенным при разной концентрации CO 2 хлопчатником, вероятно, обусловлено неспособностью гусениц младших возрастов эффективно переваривать листья кормового растения, выращенные при высоко...
