Plant stress: When is it (still) useful?

In horticulture , the status of a crop is described in several way . Also , the word ' stress ' is used , and it unremarkably defines a negative situation that should be avoided . But is this correct ? This interrogative is relevant because solving this ' stress ' often regard the role of vigor .

In the project ' Stress : when is it ( still ) utile ? ' a conceptual model is made about different types of plant life stress in a greenhouse cultivation . The heading is to get a better apprehension of plant tenseness and to keep the need for zip - eat actions when a plant is ' out of balance . '

What is flora stress?Commonly it is considered a damaging situation . But plant focus is a neutral concept : a plant senses the variety that disturbs the balance between works and environs . The plant adapts to the new position , which leads to a new balance wheel . That mean that emphasis can be beneficial for a grower , but accent can also have a negative core on the craw .

grower are point the harvest unceasingly during cultivation , which is , in fact , the induction of beneficial strain . Examples are the transition from tenacious day length to short solar day lengths to induce flowering of chrysanthemum or pruning love apple . These crop management actions make the craw to get in the desired guidance of the grower . damaging strain reactions of the crop should be avoided , like occlusion of stomate , too high temperature , or lightheaded chroma that damage the craw .

What befall in a plant in a nerve-racking situation ? After perceptual experience of the change in the environs , sure signaling pathways are set off , and ( hormonal ) signals are translocated within the works that ensures that it adapts to the new situation . Insights in these processes can be helpful ( in the future ) to observe and quash minus plant strain reactions in an other stage . Research showed that plant have a stress memory which , in some cases , can be drop dead on to the next generation . As a resultant role , temporarily experiencing accent can ensure that the plant is more resistant to the same or different types of stress in the time to come . This appendage is called ' priming . ' The usage of ' priming ' also potentially offers growers opportunity to spring up crops that are more resistant to negative stress .

The cultivation method " Next contemporaries produce " aims for symmetry in crop and greenhouse . That incriminate that climate condition ( temperature and ignitor ) can be dynamic if the intention is to attain a stable ratio between assimilated production and consumption . A crop is for good exposed to changes that can be useful but can be negative if limit are outgo . The doubtfulness is which actions run to utile tenseness reactions and when disconfirming stress effects fall out . The boundaries are not always clear and often look afterwards . supervise plant balance or plant accent would be a helpful tool and could provide insight into crop status and take " Next Generation turn " a gradation further . This pee-pee it possible to continuously bring in sixth sense into the condition of the crop and bar of taking energy - use up natural action which reduce the use of energy without disconfirming consequences for development , production , and intersection quality .
