Leafy vegetable seedlings

Lettuce, chicory, celery and much more

Specially prepared for delayed bolting in adverse conditions

Understanding theory to perfect practice

What we know so far about bolting in celery, lettuce and chicory plants is that, when they flower, there are two proteins in the leaves of the plant which physically interact. In other words, it’s the combination of these two proteins which triggers the appearance of the flower. One protein, known as FD, is produced in the tip itself and the other, called FT, comes from the leaves.

The bolting process in a celery or lettuce plant, for example, seems to work like a switch. Flowering is only triggered when the two proteins are together, separately they do nothing.

What information does the plant perceive about its surroundings?

There may be several types of information, but for the time being, we know of basically two: the duration of the day and the temperature. The difference between the length of day and night, which we call photoperiod, can be detected by plants through photoreceptors in the leaves. But temperature also helps provide information about the time of year because, in reality, the days are equally long in March as they are in October. So, the plant also detects the temperature and whether it is increasing or decreasing, although in this case, we haven’t yet identified the receptors.

Are plants able to calculate the average temperature?

Somehow, yes. We don’t know the exact details, but it’s clear that it’s not possible to trick a lettuce, celery or chicory plant by giving them a single day of heat in the middle of winter. We believe that there must be some mechanism whereby the accumulation of daily temperatures reaches a certain threshold and triggers the flowering process. Plants are capable of gathering and processing very different types of information of great complexity before deciding the time for flowering and bolting. And they don’t just gather information about the photoperiod and temperature. They also detect the availability of nutrients, stress conditions, attacks by parasites and much more.

– stress  =

– bolting

+ yield

The key is in keeping the two proteins separate for as long as possible.

At Babyplant, to achieve this, we minimise the stress the plants are under, thus avoiding the build-up of stress which activates the flowering process.

For summer crops, there’s no more reliable lettuce and chicory plant than Babyplant. Bolt-resistant and an increase of 2-4 days in the optimal days for harvesting.

Lettuce and chicory. Summer crop.

Maximum temperatures +35 °C
Solar radiation in summer months of 7-8 kWh/m²
Daylight hours +14 hours

Reduction through the use of aluminium thermal screens 3-5°C maximum temperature

Protection from solar radiation through the use of shading screens and a reduction of more than 70 hours of light throughout the seedling growth

Lettuce plant seedlings grown with less than 19 days of the cycle in the seedbed

Optimal fertilisation to achieve the perfect balance between accelerated growth and plant firmness.
