2. Introduction-
India is known for its rich diversity of medicinal plants (Gordon M.C
and David J.N.,2001 ).
Medicinal plants are the source of obtaining variety of drugs (WHO)
Natural propagation has become critical due to changing biodiversity
elements and some of the plants are threatened in their habitat.
Hence , proper propagation techniques has to be standardized to address
ex-situ conservation of threatened plants.
Plant propagation is the branch of horticulture which deals with the
production of new plants using various starter materials that is seeds
(sexual propagation) or vegetative parts (stem,tuber,corms).
3. Here we focused on two important medicinal plants :
1)Adhatoda beddomei C.B Clarke (Acanthaceae)
Medicinal use- fever, inflammation, bleeding, diabetes, disinfectant,
jaundice, antiseptic and expectorant (Patel and Bhatt ,1984).
Included in IUCN Threatened Plants List of India (Panigrahi and
Patel,2014).
2)Stereospermum tetragonum DC. (Bignoniaceae)
It is used in the preparation of chyawanprash (popular Ayurvedic
tonic) ,Sahachardithailam and Dhanwantharamthailam (An excellent
massage oils).
It has antimicrobial, antiprotozoal and anti-inflammatory properties
(Binutu et al. 1996).
4. Statement of the problem-
Adhatoda beddomei rarely sets the seeds (Panigrahi and Patel,2014);
Stereospermum tetragonum is usually propagated through seeds but
has a very poor rate of germination (Baul, 2006).
Justification of the study-
A.beddomei and S. tetragonum are medicinal plants used in for the
preparation of the medicine and is preferred by certain industries .
The study will be helpful in stabilizing the depleting species
population and improve conservation status in the wild.

Similarly, no studies have been found on Stereospermum
tetragonum .
7. Hypothesis-
Adhatoda beddomei will show more growth when plant cuttings
will be treated with 60% RRH and with the rooting substrate garden
soil: vermicompost: sand (1:1:1).
Stereospermum tetragonum will give good result when garden
soil: vermicompost: sand (1:1:1) will be used as sowing substrate.
Soaking seeds of Stereospermum tetragonum in distilled water will
induce highest germination.
Seed number in a pod depends on the length of the pod (applicable
for S.suaveolens).
9. Objectives-
To standardize optimum method for successful vegetative
propagation of Adhatoda beddomei.
To find out better planting substrate and pre-treatment for
Adhatoda beddomei.
To find the better planting substrates and pretreatments for seed
propagation of Stereospermum personatum.
Establishing a good plant stand in the field.
To study relationships of pods and seeds traits.

19. Pods and seeds traits characteristics
in Stereospermum tetragonum
Pod characteristics
Seeds characteristics
•45 healthy pods were collected to make three replications
containing 15 pods per replication.
•length ,width and no. of seeds per pod were recorded.
•Weighing of 100 seeds for 10 replicates.
•Average weight of 100 seeds.
•Seed quantity estimation( amount of seeds per kg)
• Plant population per hectare and quantity of seeds per
hectare estimation done (using secondary data).
20. Statistical Analysis
To find out the relationship between pods and seeds traits.
We tested for the normality of data by employing three
methods:1) the skewness and kurtosis test
2) the Shapiro–Wilk W test (Shapiro and Wilk, 1965), and
3) the Shapiro-Francia W' test.
In case the data is normally distributed, we used the Bartlett’s
test (NIST/SEMATECH e-Handbook of Statistical Methods, 2015)
to test the hypothesis of equality of variances across replications.
Employed the Analysis of Variance to test whether the means
from three replications are significantly different or not.
To estimate degree of influence of pod length on seed number,
we used regression analysis :
Seed number per pod = F(pod length).
Based on the R-square statistics, we selected the best fit model.

27. Discussion –
Adhatoda beddomei-
500ppm-IBA pre-treatment gave the overall best results for
germination, number of roots and length of roots per cutting with
garden soil: vermicompost: sand(1:1:1) as the sowing substrate.
Stereospermum tetragonum-
S. tetragonum had maximum seed germination when soaked in
distilled water as distilled water is having consistent content, it is free of
chemicals that would otherwise harm the germination
Coco peat is found to be the suitable sowing substrate for the growth
of the plant.
28. Pods and seeds characteristics-
Healthier and larger pods has good number of seeds that has been
proved by the statistical analysis for the hypothesis that number of
seeds depends on the length of the pods.
Plant stand estimation (using secondary data)-
Plant stand is expressed as space between plants that has been
determined on the basis of spacing been used for some common trees
that is 5 meter square from both the sides
(http://www.arborday.org/Shopping/Trees/fspacing.cfm;
Moniruzzaman et.al,2007) .
29. Conclusion-
Optimum method by means of stem cuttings for successful
vegetative propagation of Adhatoda beddomei has been
standardised.
Better planting substrate (Garden soil:Vermicompost:Sand) and
pre-treatment (IBA-500ppm) has been found out for Adhatoda
beddomei .
Better planting substrate ( cocopeat) and pretreatments (Distilled
water) for seed propagation of Stereospermum tetragonum has
been found out.
Plant stand establishment has been done in nursery only due to
limited time period.
Pods and seeds characteristics study proved that healthier and
larger pods contains the good amount of seeds
