Greenhouse is always ex vitro conditions.but ex vitro is not always greenhouse..thank you!

What's the point?

Ex Vitro plants can be grown in green house condition when the temperature, day length etc are not favorable at a particular place .

The word is greenhouse no green house, and that is correct within severe limitation. You could not grow plants, not for long, where it is economically unfeasible.

green house is used to grow strawberries ,gerberas and many other herbal plants in our country with full economic feasibility .Orchids in dry climate also need green house to get flower.

I guess in your country is economically feasible but that is not the question. Is it?

I can also grow gerberas, strawberries and orchids in my garage under ex vitro coditions, without a greenhouse.

Yes Sir,it depends totally on the temperature ,day length and humidity.In India temperate orchids grow in north India but tropical grow in peninsular parts.Its just depend on the demand.We can grow Cymbidiums in peninsular India too if we provide low temperature with proper humidity only in green house condition.Its just one example,similarly there are many examples.

I continue to ask.... What is the point?

I'm a consultand for the greenhouse industry and had worked with greenhouses for more than 38 years. The question continues to evade me.

- Is it possible to ex vitro conditions of growing to equate to greenhouses conditions? And why?

Excuse me, but I find it hard to formulate the question correctly, because I don`t know much English.

I do plant micropropagation acclimatization of aspen and birch trees before planting them in the woods. I keep this plant some time in the laboratory and then transplanted them into the greenhouse conditions. I study the morphological and physiological deviations of forest plants in greenhouses. can I use in my PhD dissertation that period, when the plants are in the lab?

I wish my german was that good. Your English is excellent. What kind of morphological and physiological deviations are you finding under greenhouse conditions as compared with natural forest conditions?

If the difference are valid I do not see why not

Sir Jose,Nice blog,Thanks for sharing.

Dear maryia, hope this paper will show some light for your question-agric.rev., 22(1): 65-67,2001

Maryia, Do you call Tissue Culture micropropagation?

Dear Maryia, What are such morphological and physiological deviations of forest plants that you are searching for? A screening for normal plants, eliminating (or studying) those with a morphophysiology out of type? If you want to screen under greenhouse conditions for deviatons that may ocur in the field, the answer is: It depends... on what you are looking for. Some morphological/physiological traits may be screened at greenhouse and be extrapolated to a field condition without problems, but other, may not, and require at least field validation. As plant physiological responses are integrated homeostatic responses, among others, to environmental factors (botic and abiotic), a greenhouse condition is different enough to the field as to produce a different phenotypic response in many traits, compared to field plants, such as gas exchange, water use efficiency, cell size, cell wall width, leaf size, canopy architecture, growth rates, secondary metabolites presence and concentration, etc., etc.,... so, it depends on physiological plasticity and elasticity, what you can see and measure as a result of an acclimatization process. If the acclimatization process alters your study variables and you cannot discount mathematically this non-experimental additive variation, you need to go to the field.

In my experience, an important factor in landing micropropagation of plants in terms of a period of landing, the duration of acclimation and climatic conditions (temperature, humidity). changing these factors, one summer you can get a three-meter aspen.

I found the optimal combination of plant adaptation to environmental conditions, and their sizes for planting in the forest (plantation target).

I have developed a scheme in which the production will not be loaded during the spring months, but gradually during the year will receive planting material, adapt it, and in spring you can plant the plants.

Although in scientific terms, I suppose, nothing new is discovered. Knowledge about the ecology and physiology of plants is sufficient to use the method of micropropagation of plants in practice.

DR BEENA Agarwal, thank you!
