Stoller's response to abiotic stress

One of the causes of reduced yield and quality can be traced to abiotic stress situations during growth. Examples of abiotic stress are: temperature (too cold and too wet), water availability (too much or too little), light intensity (too high or too low), mechanical damage (machinery, but also hail), herbicide damage, or the shortage or insufficient availability of nutrients.

These stress situations prompt the plant to produce secondary metabolites that require a lot of energy from the plant. Energy that the plant could otherwise have invested in its production.

ROS (Reactive Oxygen Components)
In a normal biological equilibrium in the plant, ROS (reactive oxygen components) are formed. ROS are reactive chemical components with oxygen as the main component. These ROS are necessary in low concentrations for the functioning of the cell. However, under extreme stress situations, the production of ROS rapidly rises to high levels that can and do damage the cell structure. This damage is called oxidative stress. The plant can easily restore this balance after a period of stress by producing plant-specific antioxidants, but this is often a slow process, which can cause considerable damage to the cells.

Ethylene damage
A second consequence of a stress situation is that the plant hormone balance is disrupted and an increased production of ethylene takes place. Ethylene accelerates the aging process in the plant (reduction in yield) and also reduces the availability and transport of calcium in the plant. A higher concentration of ethylene in the plant increases the concentration of oxalic acid, which will bond with the calcium in the form of crystals. These crystals ensure that the calcium is no longer available for plant processes.

Stoller solutions
Stoller has developed 2 special products for both stress situations, each with a specific application to prevent yield and quality loss due to abiotic stress.

Bioforge: to apply after a high intensity of stress where the stress period has been short and intense.

By immediately spraying Bioforge after an acute period of stress, the plant is optimally supported in a faster recovery and the quality damage will be limited.

.: apply during a longer moderate stress situation.

By performing three sprays (interval 7 days) with Hold during the crucial growth periods of the plant, the plant is supported in reducing ethylene production and improving the availability of calcium. This prevents any loss of yield and improves the quality of the end product.
