“…The chlorophyll content after treatment with 10 ppm AsA was higher than that in the control (Figure 6D ). Recently, Ishizawa et al ( 2017 ) reported that L. minor accumulated ROS and expressed an evident antioxidant enzyme activity. Furthermore, the antioxidant enzyme activity was markedly increased in the presence of plant growth-inhibiting bacteria.…”

Gibberellic acid (GA3), indole-3-acetic acid (IAA), salicylic acid (SA), abscidic acid (ABA), jasmonic acid (JA) 1-amino cyclopropane-1-carboxylic acid (ACC) and aminoethoxyvinylglycine (AVG) are popular growth regulators of plants. However, the effects of their exogenous addition on the biomass production of aquatic plants, including Lemnoideae plants, “duckweeds,” are largely unknown. In this study, the growth of Lemna minor was tested for 10 d in Hoagland medium containing each compound at different concentrations of 0–50 μM. GA3, IAA, and SA were found to have no apparent positive effect on the growth at all concentrations tested. Conversely, ACC and JA moderately and AVG and ABA severely inhibited the growth of L. minor. Among the tested compounds, ascorbic acid had an apparent growth-promoting effect.

“…Thus, it is necessary to search for aquatic microorganisms that can promote duckweed growth and/or increase its tolerance to stresses. Microbial communities living in symbiosis with duckweed include both plant growth‐promoting bacteria (PGPB) and plant growth‐inhibiting bacteria (Ishizawa, Kuroda, Morikawa, & Ike, 2017). Acinetobacter calcoaceticus P23, the first PGPB strain discovered in duckweed ( L. minor ), has been proved to effectively increase chlorophyll content and promote plant growth in both laboratory and natural waters (Suzuki, Sugawara, Miwa, & Morikawa, 2014; Toyama et al., 2017).…”

“…From the explanation above, it proves that the provision of fertilization and humic acid showed response in the increasing of dry weight of maize plant pipe on Andisol soil both in Bisi-2 and Pioneer-35 cultivars. In addition according to Ishizawa et al (2017), applying phosphorus fertilizer through chemical or biological fertilizers can increase the dry weight of plants.…”

One way to improve maize (Zea mays L.) production is through land extension using Andisol land. However, andisol soil has phosphate (P) fixation problem due to the high amorphous material. Hence, the use of organic material in the form of humic acid that has greater affinity to amorphous minerals is recommended to solve the problem. This research was conducted in February-May 2017 at Tri Dharma field of Faculty of Agriculture, Gadjah Mada University. The Andisol land used has a low available P category from Datar, West Java and Wonosobo, Central Java. This research was arranged in a Randomized Complete Block Design (RCBD), consisting of 2 factors. The first factor was maize cultivar (Bisi-2 and Pioneer-35). The second factor was the doses of humic acid, consisting of control treatment (without fertilizer and humic acid), NPK without humic acid, and NPK + humic acid at 5%, 10%, and 15%. The percentage of humic acid given, based on the amount of NPK 16:16:16 fertilizer, was 350 kg ha-1. Fertilization was applied 3 times 100 kg ha-1 on 1 WAP, 150 kg ha-1 at 3 WAP and 100 kg ha-1 at 7 WAP. The results is, humic acid treatment had the same effect with NPK fertilization treatment only and control on P available Andisol soil. Humic acid, also has the same effect with NPK fertilizer treatment in increasing the yield component of 100 seeds weight, dry weight of seeds, harvest index, length of cobs and productivity.
