10 Αυγ 2022 · Iron deficiency in plants is chiefly because of the poor solubility of this nutrient in the soil particularly in neutral and alkaline conditions despite of its abundance in the surroundings (Rai et al. 2021) (normally ranges between 20,000 and 100,000 lb/a in the plow layer) (Pourbabaee et al. 2018).
If plants are iron deficient, the newer leaves will grow in a pale light green, yellow, or even white with no abnormal spotting, while older leaves will appear normal. The veins of the new leaf growth will remain dark compared to the discolored leaves. Iron is used in several enzymes and pigments.
1 Νοε 2019 · Aquaponic systems are often iron deficient due to low amounts of iron in commercial fish feeds. Therefore, iron needs to be supplemented to ensure optimal plant performance. Adding these supplements requires close management of the system, and careful selection of chelating substances as the Fe-chelate bioavailability is environment dependent.
20 Απρ 2024 · In addition to water testing and pH monitoring, observing plant health provides valuable insights into the iron status of aquaponic systems. Symptoms of iron deficiency, such as chlorosis, stunted growth, and leaf curling, can serve as indicators of insufficient iron availability to plants.
5 Φεβ 2016 · In cases of iron deficiency, the most evident effect in leaves is a generalized chlorosis, caused by reduced chlorophyll that can cause a decrease in CO 2 assimilation rate. Also, carotenoids such as β-carotene and neoxanthin suffer reductions in availability.
23 Οκτ 2021 · The iron deficiency caused a significant increase in ROS production mainly hydrogen peroxide and superoxide radicals in leaves of maize and sunflower plants (Ranieri et al., 2001; Sun et al., 2007) and peroxides in peanut (Singh & Chaudhari, 1992).
