Claims
- 1. A method for testing abiotic stress factors and bioactivity of natural, synthetic and semisynthetic compounds using Bacopa monnieri plant, which comprises growing the said plant and plant parts aseptically in MS 0 basal medium with agar in microcentrifuge tubes by adding the compounds to be tested either to the culture media or by spraying the said compounds on the plant or plant parts or on the said medium to detect the distinct morphological and cytological responses.
- 2. A method as claimed in claim 1, wherein the said compounds used are either in pure or crude extract form.
- 3. A method as claimed in claim 1, wherein the group of morphological responses to be detected may be selected from callus initiation, shoot induction, root induction, necrosis and death.
- 4. A method as claimed in claim 1, wherein the cytological response to be detected may be selected from the group comprising mitotic index and C-mitosis.
- 5. A method as claimed in claim 1 wherein the compound used for bio-te sting includes growth promoters selected from the group comprising auxins and cytokinins.
- 6. A method as claimed in claim 1 wherein the auxins used are selected from the group comprising but not limited to Indole 3 acetic acid and 2, 4-Dichlorophenoxy acetic acid.
- 7. A method as claimed in claim 1, wherein the cytokinins used are selected from the group comprising but not limited to 6-Benzyl amino purine and kinetin.
- 8. A method as claimed in claim 1, wherein the compounds used for biotesting includes growth inhibitors selected from but not limited to the group comprising nalidixic acid and abscisic acid.
- 9. A method as claimed in claim 1, wherein the compounds used for biotesting includes weedicidal compounds.
- 10. A method as claimed in claim 1, wherein the weedicidal compound includes 2,4-Dichlorophenoxy acetic acid.
- 11. A method as claimed in claim 1, wherein the compounds used for biotesting comprise antimitotic and anticancerous compounds.
- 12. A method as claimed in claim 11, wherein the antimitotic and anticancerous compounds are selected from the group comprising but not limited to taxol, trichothecene, vincristine, vinblastine and nalidixic acid.
- 13. A method as claimed in claim 1, wherein the compounds used for biotesting include cytotoxic compounds.
- 14. A method as claimed in claim 1, wherein the cytotoxic compounds are selected from the group consisting of but not limited to menthol, mint oil, artemisia oil, basil oil and essential oil components.
- 15. A method as claimed in claim 1, wherein the abiotic stress factors used are selected from the group consisting of radiation, Ultra violet rays, gamma rays, radioactivity, heat shock and cold shock conditions in the environment.
- 16. A method as claimed in claim 1 wherein bioactivity of growth promoter compounds is detected by profuse root initiation, root thickening, callusing and regeneration formed during a period ranging between 7 to 15 days.
- 17. A method as claimed in claim 1, wherein bio-activity of growth inhibiting compounds is detected by absence of root initiation, wilting, withering within 2 weeks.
- 18. A method as claimed in claim 1, wherein bioactivity of weedicidal compounds is detected by necrosis and death of the explant within a period of 3 days.
- 19. A method as claimed in claim 1, wherein bioactivity of antimitotic and anticancerous compounds is detected by reduction in cell division and miotic index within 7 days.
- 20. A method as claimed in claim 1, wherein bioactivity of cytotoxic compounds is detected by complete loss of chlorophyll within 3 days.
- 21. A method as claimed in claim 1, wherein the response to abiotic stress factors is detected by lethality after treating for 2 hours or more with the UV radiation within a period of 15 days.
- 22. A method as claimed in claim 1, wherein the response to abiotic stress factors is detected by absence of shoot proliferation and reduction in shoot elongation and rooting, and increase in lethality at a dose greater than 5Kr gamma radiation within a period of 15 days.
- 23. A method as claimed in claim 1, wherein the response to abiotic stress factors is detected by temperature sensitivity of Bacopa monnieri plants at a temperature of 80° C. for 20 seconds or more within a period of 7 days.
- 24. A method as claimed in claim 1, wherein the response to abiotic stress factors is detected by temperature sensitivity of Bacopa monnieri plants at a temperature of 50° C. for 3 min. or more within a period of 7 days.
- 25. A method as claimed in claim 1, wherein the response to abiotic stress factors is detected by temperature sensitivity of Bacopa monnieri plants at a temperature of −80° C. for 4 min or more with a period of 7 days.
- 26. A method as claimed in claim 1, wherein the response to abiotic stress factors is detected by temperature sensitivity of Bacopa monnieri plants at a temperature of −20° C. for 10 min or more within a period of 7 days.
