X-Ray Wavelengths and Photosynthesis - STELTHY :leaf:

I have been looking at the entire spectrum and after a lot of reading have ruled out Infra-red,Micro-waves,UV-A,UV-C & Gamma Ray... However I have found that controlled voltage and filtered appliance of X-Ray is beneficial to plants... More to come - STELTHY

I've found some interesting info on X-ray beams applied to plants with positive effects.. However voltage and filtration is needed.. here is some blurb :-

STIMULATIVE EFFECTS OF X-RAYS ON PLANT GROWTH'

(WITH FOUR FIGURES)



Introduction


During the period since the discovery of x-rays by R6NTGEN in 1895, a vast amount of work has been done in which these radiations have been used for clinical diagnosis and therapy. The practical applications of x-rays in medicine and surgery make it necessary to know the effect which x-rays produce upon the living organism. Many investigators have suggested on the basis of general observations that small doses of x-rays may stimulate cellular activity and growth, but convincing proof of such action has been wanting. In more recent years such claims have been discounted in favor of the belief that x-rays are always more or less destructive in action, and tend to retard growth. It is not the purpose of this preliminary report to survey the literature dealing with the effects of x-ray treatments upon plants. It has been found that every part of the plant body can be profoundly modified by appropriate treatments. Cytological and histological examination of treated cells and tissues reveals striking changes in the organization of the protoplasm and of organs derived from the treated meristems.

Most frequently the results described are of a destructive nature. The protoplasm is partially disorganized; chromosomes are vacuolated or fragmented; the cell division mechanism functions imperfectly, showing unequal distribution of chromosomes, non-disjunctions, translocation of pieces of chromosomes from one to some other non homologous chromosome, etc. Gene changes may be produced, often injurious in character, with resulting lethal effects and tendency to sterility. The results obtained by McKAY and GOODSPEED on cotton are typical. Many mutations have been induced in maize and barley and tobacco, but it has been questioned whether there are any progressive evolutionary changes induced by x-ray treatments.

All vegetative parts are subject to injury by x-rays. Root tips may become bulbous and swollen, with tumor-like enlargements in which giant cells may occur. Stems become fasciated under strong treatments. Leaves are injured readily; they become asymmetric and crumpled in appearance, develop deep sinuosities, and often show irregular development of chlorophyll. The sunflower shows these injuries in typical fashion, the leaves becoming pocked and marked as though they were suffering from a mosaic. This investigation was aided in part by a grant to the University of Chicago from the Rockefeller Foundation.

Conclusion

From the results obtained in these preliminary experiments it is concluded that if the x-rays are properly filtered to decrease the intensity of the beam, or to decrease the proportion of the longer radiations, and if the quantity of energy used is adjusted to the specific requirements of the plants by control of the duration of radiation, and of the voltage and amperage used, plants can be stimulated to show increased growth rates.


Summary

1. A few preliminary experiments are described which indicate that under appropriate conditions of treatment, x-rays produce stimulative effects upon plant growth. Wheat, corn, oats, and sunflower seedlings have been used.

2. The seeds were treated in an early stage of germination after soaking for 24 hours in a closed moist chamber on a substrate of cellueotton
saturated with water. The seeds are not submerged during soaking, but
are wet on one side, and in contact with air.

3. The conditions which we believe necessary for such stimulative action are: the use of metallic screens, high voltage and low amperage, and brief exposures. The total dosage for stimulation does not much exceed 100 r-units. Even with the 1-mm. aluminum screen sunflowers given 150-200 r-units were overtreated. Optimum growth occurred with about 115 r-units (3 minutes).

4. There is some evidence of increased sugar content and increased respiration of treated seedlings.

** For the record I doubt I'll be able to get my hands on the technology to try this out with Cannabis seedling's and Cannabis plants in Veg, but there's no harm in looking... I am aware of high volumes of radiation are a health risk and so plan to do alot more research 1st..

I will add more to this thread soon hope you find this interesting - STELTHY
