Impact of Plant Growth Regulators on Performance of Strawberry Plant: A Review

Abstract

Plant growth regulators (PGRs) are substances that help in controlling the growth and development of plants. They're pretty important because they're used in various areas of research, helping to improve how well crops grow. Researchers are looking at how PGRs affect the growth and production of a specific type of strawberry plant, called Fragaria × ananassa. It turns out that these plants are affected by different PGRs like auxins, gibberellin, and cytokinin’s. Studies have shown that using these substances can change how cells divide, grow bigger, and become different types in strawberries. One interesting thing is that auxins, like NAA, can make the roots of the plants grow deeper into the soil, which helps them absorb more nutrients. When strawberry plants are treated with a certain amount of NAA (about 19.97 mg/l), they show higher levels of things like TSS (total soluble solids), titrable acidity (how acidic something is), and total sugars. This suggests that using NAA can make strawberries sweeter and potentially improve their taste and quality. Gibberellins are super important for making plant stems grow longer and helping them flower. They can even affect how a strawberry plant looks overall. When we used a mix of 150 parts per million of GA3 and 0.4% zinc on the plants, they bloomed in the shortest time, around 113.4 to 116.8 days. Cytokinins are also great for making plants produce more cells, which helps them grow.
