Effect of GA3 and Gly Plant Growth Regulators on Productivity and Sugar Content of Sugarcane

Abstract

The use of plant growth regulators is one effective solution to improve sugarcane yields and sugar content in several countries. In this study, we examined the role of gibberellin acid (GA3) and glyphosate (Gly) plant growth regulators to determine the appropriate concentration of GA3 and Gly to increase the yield of sugarcane and sugar accumulation, respectively. The statistical results showed that GA3 was sprayed at 150 ppm to increment the actual yield by 19.94%; sucrose accumulation increased by 2.21%. With Gly treatment, although the yield decreased by 3.17%, sucrose accumulation increased by 11.27% compared to control trials. In this study, the combined concentration of 150 ppm of both GA3 and Gly gave the best results, for which sucrose accumulation increased from 2.21% to 10.74% and from 19.94% to 20.97% for actual yield. The results led to increased net income compared to the control. To address concerns about residues of plant growth regulators, residues of GA3 and Gly were evaluated after the sugarcane harvest using the HPLC and UV-vis methods, respectively. The analyzed results showed that their residues were lower than what is permitted in several countries. This showed the applicability of the study, on a large scale, to increase sucrose accumulation, productivity of sugarcane, and profit for farmers.

Initiation of Flowering and Bulbils in Shallot with Various Treatments in Tropical Regions

“…The results showed that GA3 treatment produced bulbils with the highest weight and diameter (Table 2). This is because GA3 plays a role in sucrose phosphosynthase activity, one of the main enzymes involved in sucrose synthesis and promotes tissue proliferation, which leads to a better assimilation process (Nguyen et al, 2019). The number of bulbils formed, weight and diameter of bulbils in GA3 treatment was not significantly different from the wound treatment of flower stalks.…”

Pengaruh Konsentrasi Zat Pengatur Tumbuh dan Bagian Asal Bibit Terhadap Pertumbuhan Vegetatif Pembibitan Tebu

“…Penggunaan ZPT di bidang pertanian dapat memberikan kontribusi besar dalam peningkatan pertumbuhan, produksi, dan kualitas tanaman tebu (Patel & Chaudhary, 2018). Penggunan ZPT pada pertanaman tebu juga mampu meningkatan jumlah akumulasi sukrosa, produktivitas dan juga keuntungan bagi petani tebu (Nguyen, Dang, Nguyen, & Tran, 2019). Salah satu ZPT yang telah banyak dikenal yaitu Atonik yang memiliki kandungan natrium para-nitrofenolat PNP (0,3%), natrium orto-nitrofenolat ONP (0,2%) dan natrium 5-nitroguaiacolate 5NG (0,1%) (Kociraa et al, 2017) yang mampu meningkatkan pertumbuhan vegetatif dan produksi (Banful & Attivor, 2017).…”

Dual Arginine and Glutamic Amino Acids Delivery Effectiveness of Injectable Chitosan-Poloxamer P407 towards Wound Healing Application

“…Copolymer solution with predetermined Glu/Arg concentration was lyophilized for further use in Glu/Arg content evaluation and in vitro release behavior. Since it is difficult to determine the content of Glu/ Arg loaded CS-P407 hydrogels, a mediated-reagent (FMOC-Cl) was used to quantify different amino acids via reactions between amino acids and FMOC-Cl [18][19][20]. Pure Glu/Arg was dissolved in H 2 O with various concentrations (in the range from 1 to 10 ppm).…”
