Quando ha luogo l’evaporazione, gli stomi devono essere aperti, una condizione cruciale per l’assorbimento di CO2. Una coltura attiva, pertanto, è anche in grado di assorbire una grande quantità di CO2.

When the plant evaporates, the stomata must be open. This is a very important condition for the uptake of CO2. An active crop is also capable of absorbing a lot of CO2.

La gran parte del processo di evaporazione è causato dalla radiazione, come accade anche nel caso del vapore acqueo che fuoriesce da un bollitore: la radiazione riscalda l’acqua all’interno della pianta che viene eliminata attraverso gli stomi.

Most evaporation is caused by radiation. This can be compared to the steam that is released by a whistling kettle. Radiation heats up the water in the plant, which is released through the stomata.

Microclima: Un’eccessiva distanza tra le piante, un substrato asciutto o un eccessivo movimento dell’aria può causare un’eccessiva evaporazione della pianta, provocando la chiusura eccessiva degli stomi.

Microclimate: A plant distance that is too large, a dry substrate or much air movement can cause significant plant evaporation and therefore the stomas will close too much. This can have a negative impact on CO2 absorption and, therefore, indirectly on growth.

In questo modo, la carenza di acqua si manifesta più tardi e la coltura è più a lungo in grado di eliminare il calore in eccesso grazie all’evaporazione. Socchiudendo invece di chiudere gli stomi, il calore causato dall’esposizione verrà impiegato maggiormente perl’assimilazione e rilasciato in gran parte mediante il processo di convezione.

By using high pressure atomization, amongst other things, more heat is extracted from the air in the greenhouse by the water applied. Keeping a higher temperature and RH in the greenhouse implies that ventilation is required later and that more CO2 stays in the greenhouse, as a result of which assimilation is increased. If it is not possible to keep the RH up to standard, screens will have to be used earlier in order to prevent the plants from suffering stress (source: *).

Il numero di stomi di una coltura può oscillare tra 60 e 100 per mm2 e dipende notevolmente dal tipo di coltura, dall’età e dall’area della foglia in combinazione alle condizioni di crescita. Nelle colture che presentano molti stomi, questi ultimi mostrano dimensioni ridotte, mentre se gli stomi sono pochi, risultano più grandi.

The number of stomata on a plant can vary from 60 to 1000 per mm2 and depends strongly on the crop, the age and the place on the leaf together with the growth conditions. In crops with a lot of stomata, these are often small. If there are few stomata, then they are usually large. Stomata are found on the top of leaves, but underneath there are many more. All crops have more stomata per square millimetre when the humidity is high and they are ±30% larger as well. As a consequence, the total surface area of stomata per square millimetre of leaf surface increases considerably. The crop responds to the circumstances that make that evaporation difficult by increasing the total surface at the openings in the leaf.

VPD is an excellent way of estimating to what extent the stomata are open and whether we are dealing with an active crop or not. The VPD that can be read on the climate computer is a calculated value that combines the temperature and the humidity of the greenhouse air with the plant temperature. However, control according to VPD in plants with a CAM photosynthesis is not possible. As the stomata are predominantly closed in the daytime, the plant temperature will almost always be higher than the greenhouse air and hardly any evaporation takes place. Therefore, a VPD calculated on the climate computer will give a distorted image in Phalaenopsis and cannot really be used as cultivation control.

The influence of the climate on plant health is quite substantial. In the first place, it affects the growth processes of the plant. When the humidity of the greenhouse air is high, this will generally have a positive effect on the growth of the plants and thus on production. The only drawback is that fungi and bacteria also grow better in moister conditions. This should not cause any problems, but it is necessary that the greenhouse climate can get rid of the excess moisture so that the plants also have the chance to evaporate. We create an ‘active climate’!

L’umidità dell’aria influisce sulla crescita delle colture soprattutto per le sue conseguenze sulla superficie fogliare totale e sulla fotosintesi. Per la fotosintesi, fattori come la superficie fogliare e uno scambio di CO2 ottimale attraverso gli stomi sono estremamente importanti, e l’umidità dell’aria influisce su entrambi.

Humidity affects the growth of a crop, especially as a consequence of its influence on the total leaf area and on photosynthesis. The leaf surface and a good exchange of CO2 via the stomata are very important for photosynthesis. Humidity influences both of them. In the event of a moisture deficit of 5-10 g/m3, the influence on the CO2 exchange is crucial. However, in the case of a smaller moisture deficit, the adaptation of the leaf area is decisive. The leaf area changes due to the impact of the humidity as regards the formation of leaves and the stretching of cells. It takes some time before you notice this crop adaptation, since the process is quite slow.

Mediante un valore URA alto, gli stomi sono completamente aperti e la pianta è in grado di assimilare facilmente CO2, che può portare infine a un aumento del rendimento di decine di punti percentuali in più rispetto ai risultati di un ambiente meno umidificato.

Growing at a high relative humidity (RH) / low moisture deficit (MD) is of great importance for Anthurium to reach the maximum generation of assimilates. Due to a high RH, the stomata are opened to a maximum and CO2 can be absorbed easily by the plant. This can lead eventually to a very high percentage of greater yield compared to not humidifying.

Si tratta di condizioni che hanno conseguenze anche di notte. Le radici aeree non crescono più nel vaso ma orizzontalmente e, a causa del clima troppo arido intorno alla pianta, anche gli stomi risulteranno maggiormente chiusi.

The cultivation benefits from good water management of the pot. The humidity of the air has a major impact on this. When the humidity is too low, the top layer will dry out considerably, which will result in an excessively dry microclimate (i.e. the climate at plant level) for the plant. This also has an impact at night. The secondary roots will not grow any longer in the pot, but rather horizontally, and also the stomata will be closed more because the climate around the plant is too dry. When this situation lasts too long, the dry top layer of the substrate can become irreversible. This means that it is impossible to humidify this layer. High humidity ensures good moisture management around the plant, which turns out to be beneficial for plant growth.

Per verificare se gli stomi sono aperti si può ricorrere all’uso dell’alcol (>80%). Se si applica l’alcol strofinandolo nella parte inferiore della foglia, la sostanza attraverserà gli stomi e verrà assorbita dalla foglia che, per reazione, diventerà verde scuro.

In order to keep the stomata open, it is important to reduce the evaporation of the plant when there is more irradiation. By keeping the humidity in the greenhouse high, evaporation will be reduced. In addition, the greenhouse temperature can be lowered by introducing humidity, as a result of which the plant has to cool less through evaporation. Finally, the crop can be slightly moistened so that the evaporating water can cool the crop or the greenhouse temperature.

Per mantenere aperti gli stomi è importante limitare l’evaporazione della pianta in caso di una maggiore esposizione. Grazie al mantenimento di un alto livello di umidità nella serra, è possibile limitare il processo di evaporazione.

In addition, the temperature of a plant on a sunny day is mainly regulated by cooling through evaporation. Evaporating water can evacuate a lot of plant heat and is an efficient way of cooling for a plant. Open stomata ensure that a lot of heat can be evacuated. By closing the stomata, the plant temperature will often increase quickly.

Keeping the stomata open for photosynthesis is extremely important. When the stomata are completely closed, no photosynthesis will be possible. When this process halts, the plant will not grow. By keeping the humidity in the greenhouse and around the plant at the right level, the plant will be able to keep its stomata open. Then CO2 can be absorbed and the plant temperature can be regulated through evaporation.

With a higher greenhouse humidity level, the plant can process more incoming radiation. This is a consequence of the fact that a plant will evaporate less water in this situation. It creates less rapidly a shortage of water as a result of which the crop is able to continue regulating the release of temperature through evaporation for longer. By ‘squeezing’ instead of closing the stomata, more incoming radiation can be used for assimilation and a larger share of the heat will be emitted by convection.

To what extent a plant can evaporate and take up CO2 depends on a number of factors which are mainly related to the greenhouse climate. When we talk about evaporation, we usually mention in the same breath the so-called stomatal resistance. This is a factor that regulates the opening of the stomata. A low resistance means that the stomata are open to the maximum and that there are no obstacles to evaporation and/or CO2 uptake.
