The magical effect of Gibberellic Acid: The secret to rejuvenating plants
In recent years, the plant growth regulator Gibberellic Acid (GA3) has set off a revolutionary breakthrough in the fields of agriculture and horticulture. From the laboratory to the field, this "plant life switch" is subverting traditional planting cognition. According to a 2022 study by the Chinese Academy of Agricultural Sciences, the scientific use of Gibberellic Acid (GA3) can increase crop yields by 15%-20%, and 37 countries around the world have included it in the official promotion catalog.
1. "Accelerator" of plant growth: Breaking through genetic restrictions
Gibberellic Acid (GA3) can significantly improve the efficiency of cell elongation synthesis by activating the Gibberellic Acid (GA3) receptor protein in plants. Experiments at Shizuoka University in Japan confirmed that the stem elongation rate of tomato seedlings sprayed with 0.5ppm GA3 was 2.3 times faster than that of the control group. What is even more shocking is that the team of China Agricultural University has successfully increased the efficiency of the Gibberellic Acid (GA3) synthesis pathway by 40 times through gene editing technology, making the yield of a single corn plant exceed the 1,200 kg mark.
2. The "golden key" to break dormancy: awakening the dormant vitality
Gibberellic Acid (GA3) has demonstrated precise regulation capabilities for dormant crops such as apples and grapes. Research from the University of California, Davis, USA, shows that spraying 200ppm GA3 after leaf fall in winter can shorten the dormancy period by 30-45 days. In 2023, the Dingxi apple producing area in Gansu Province achieved a 97.6% fruit-bearing rate of young trees in the same year through the "pre-bud + pre-flowering" double spraying method, an increase of 82% over traditional planting.
3. The "control station" for flowering and fruiting: precise control of the plant life cycle
The mechanism of Gibberellic Acid (GA3) for flowering regulation is exquisite. The Institute of Crop Sciences of the Chinese Academy of Agricultural Sciences found that GA3 and ethylene have a dynamic equilibrium relationship: spraying 15ppm GA3 during the expansion period of citrus fruits can coordinate sugar accumulation and ripening speed simultaneously. A paper published in Plant Biology by Gyeongju University in South Korea in 2023 pointed out that by spraying GA3 with gradients (10ppm→20ppm→30ppm), the continuous fruiting period of strawberries can be extended to 9 months, and the yield can be increased by 3.2 times.
4. "Protective shield" with upgraded resistance to adversity: the ultimate solution to the climate crisis
Facing the challenges of extreme weather, Gibberellic Acid (GA3) has shown unique advantages. During the heavy rains in Henan in 2023, wheat grower Wang Jianguo adopted the "pre-disaster spraying of 50ppm GA3 + post-disaster spraying of 100ppm GA3" scheme to achieve a miracle of 832 kg per mu. Data from the Institute of Plant Physiology of the Russian Academy of Sciences showed that the root waterlogging resistance index of corn treated with GA3 increased to 8.7 (the control group was 4.2), and the leaf water retention capacity under drought stress increased by 65%.
In the context of consumption upgrading, Gibberellic Acid (GA3) is reshaping the agricultural product value chain. In 2023, Hainan mango production areas achieved a sugar-acid ratio of 18:1 through "spraying 10ppm GA3 before flowering + spraying 20ppm GA3 before harvesting", with a premium rate of up to 300%. Chilean grape growers use GA3 precise control technology to achieve a fruit uniformity of 98.7%, doubling the export price.
