“…According to the findings of Effendy et al (2015), Fe concentration had an effect on the root length of pineapple plants 1-5 weeks after treatment, and root length inhibition occurred as Fe concentration increased. The research by Shiwachi et al (2006) also reported that the level of Fe 60 mg L -1 was able to reduce the number of roots up to 58% compared to controls. Excess iron can damage the root system in rice (Onyango et al 2019).…”

Iron (Fe) is a micro essential needed by plants in small amounts and can be toxic when available in large quantities. This study aimed to evaluate how Fe exposure affects the growth of C. callothyrsus and L. leucocephala seedlings. This study used a completely randomized design with factorial, where the first factor consisted of two levels of seedlings (C. calothyrsus and L. leucocephala), and the second factor consisted of Fe concentration which consisted of 8 levels (0, 0.25, 0.5, 0.75, 1, 1.25, 1.5, and 1.75 mM). The results showed that treatment of seedlings species and concentration of Fe was able to significantly affect the growth parameters (height, root length, root dry weight, shoots, and plant dry weight) of seedlings. The control treatment (without Fe) showed the highest growth response compared to those treated with Fe exposure and an increase in Fe concentration was able to reduce all growth parameters in both seedlings. The 0.5 mM Fe concentration reduced all growth parameters of C. calothyrsus drastically, while in L. leucocephala, the Fe 0.75 concentration was able to decrease all growth parameters drastically. The tolerance index of both seedlings decreased with increasing Fe concentration. The rate of photosynthesis did not show a significant difference between treatments, meanwhile, it had a significant effect on chlorophyll affect chlorophyll (a, b, and total chlorophyll) and carotenoid content. The highest Fe content in C. calothyrsus seedlings was at a concentration of 1.5 mM (4.40%), while in L. leucocephala seedlings, the highest Fe content was at 1.7 mM (2.87%).

“…The results of several studies also reported that increasing the concentration of Fe can reduce plant growth, such as pineapple [18], Vaccinicum macrocarpon [19], soybean [20,21], and Disccorea spp. [22]. Growth inhibition due to Fe toxicity is thought to be caused by an increase in Fe content in plants which interferes with plant metabolic processes and damages plant cell structures [23], and an increase in Fe concentration is able to inhibit nutrient absorption, so that plants experience nutrient deficiency (deficiency).…”

Fe is one of the microessential plants needed in low concentrations. The purpose of this study was to examine the growth response of three forest seedlings to iron exposure in water culture media. This study used a completely randomized design (CRD) with Fe dose treatment and consisted of 9 levels, namely 0, 0.5, 0.1, 1.5, and 2, with 3 replications each and each replication consisting of 3 plant units. The plants used consisted of Ochroma bicolor, Shorea macrophylla, and Senna siamea. The results of this study showed that Fe exposure treatment had a significant effect on the three seedlings on all growth parameters (height, root length, root dry weight, shoots, and total dry weight). Increasing the concentration of Fe can reduce all growth parameters. The three seedlings have different tolerance levels. Fe exposure treatment had a significant effect on the SPAD index only on O. bicolor and S. seamea seedlings. S. macrophylla seedlings had the highest tolerance index value compared to the other two seedlings. This indicated that S. macrophylla seedlings had higher resistance than the other two seedlings to Fe exposure.
