Exogenous GABA boosts cucumber growth under salt stress, improving crop yield.
The researchers studied how adding a substance called γ-aminobutyric acid (GABA) affected the growth and mineral content of cucumber seedlings when they were exposed to different levels of salt stress. They found that high salt levels inhibited the growth of the seedlings and changed the levels of certain minerals in the plants. However, adding GABA helped the seedlings grow better and reduced the negative effects of salt stress on them. In particular, the seedlings treated with GABA were heavier and healthier compared to those not treated with GABA. This shows that GABA can protect cucumber seedlings from the harmful effects of salt stress by helping them absorb important nutrients.
