⮚ Catharanthus roseus (commonly Known as Madagascar periwinkle,
Periwinkle, Vinca, Sadabahar, Sadaphuli), Catharanthus roseus (L.) G.
Don belongs to the family Apocynaceae (Pereira et al., 2010).
⮚ Origin-Madagascar, Africa (Pereira et al., 2010).
⮚ It is an important medicinal plant of Apocynaceae containing abundant
useful alkaloids, used in diabetes, blood pressure, asthma, constipation,
cancer and menstrual problems (Das S et al., 2017).
⮚ Catharanthus roseus is an evergreen sub herb or herbaceous plant
(Hogan., 2003).
⮚ The chromosome number of all species of the genus Catharanthus is
2n=16 (Mendioro et al, 2005).

⮚ In Madagascar, The bitter and astringent leaves are used as vomitive, roots used as hemostatic and
toothache remedies
⮚ Varieties:
Based on flower colour
1. Pink colour flowered – rosea (contains more of alkaloids)
2. White colour flowered – alba
3. White with pink or yellow ring in the orifice region – occellata

1. Catharanthus roseus plant is being exploited on a large scale on commercial basis for its
medicinal property (valuable alkaloids like vincristine, vinblastine act as anti-cancer and
agmalicine act as anti-hypertensive compound).
2. Conventionally, it is being propagated through seed, vegetative splits, stem cuttings, where the
success is around only 70% and when propagated through seeds, the germination is only 30%.
3. Due to low productivity and high production costs of alkaloids by cultures of Catharanthus
roseus, non-conventional methods have to be employed for better production.
4. Tissue culture techniques are being widely used to produce uniform quality, disease free plants
at a faster rate within a limited space.

SUMMARY OF THE PROGRAMME
14-11-2022 Wani Aditya Balasaheb 25
⮚ The present investigation aims “Micropropagation of Madagascar periwinkle (Catharanthus roseus)” and the
related work were carried out in Plant Tissue Culture Laboratory.
⮚ Demand for the healthy planting material of Madagascar periwinkle is very high.
⮚ As this herb, is an important medicinal plant, it is becoming a vulnerable species due to its low seed
germination percentage and poor seed viability. Productions of large numbers of Catharanthus roseus plants
were possible through in vitro micro-propagation techniques.
⮚ Propagation of Madagascar periwinkle through tissue culture is reliable solution to produced disease and
virus free planting material to the farmers.
⮚ In this study sterilization protocol were standardized.
⮚ Growth regulator’s play an important role on growth and development of Micropropagation of Madagascar
periwinkle shoot culture.

  • 4. ⮚ Catharanthus roseus (commonly Known as Madagascar periwinkle, Periwinkle, Vinca, Sadabahar, Sadaphuli), Catharanthus roseus (L.) G. Don belongs to the family Apocynaceae (Pereira et al., 2010). ⮚ Origin-Madagascar, Africa (Pereira et al., 2010). ⮚ It is an important medicinal plant of Apocynaceae containing abundant useful alkaloids, used in diabetes, blood pressure, asthma, constipation, cancer and menstrual problems (Das S et al., 2017). ⮚ Catharanthus roseus is an evergreen sub herb or herbaceous plant (Hogan., 2003). ⮚ The chromosome number of all species of the genus Catharanthus is 2n=16 (Mendioro et al, 2005). INTRODUCTION Fig no.1 Periwinkle 14-11-2022 Wani Aditya Balasaheb 4
  • 5. ⮚ In Madagascar, The bitter and astringent leaves are used as vomitive, roots used as hemostatic and toothache remedies ⮚ Varieties: Based on flower colour 1. Pink colour flowered – rosea (contains more of alkaloids) 2. White colour flowered – alba 3. White with pink or yellow ring in the orifice region – occellata 14-11-2022 Wani Aditya Balasaheb 5
  • 6. 1. Catharanthus roseus plant is being exploited on a large scale on commercial basis for its medicinal property (valuable alkaloids like vincristine, vinblastine act as anti-cancer and agmalicine act as anti-hypertensive compound). 2. Conventionally, it is being propagated through seed, vegetative splits, stem cuttings, where the success is around only 70% and when propagated through seeds, the germination is only 30%. 3. Due to low productivity and high production costs of alkaloids by cultures of Catharanthus roseus, non-conventional methods have to be employed for better production. 4. Tissue culture techniques are being widely used to produce uniform quality, disease free plants at a faster rate within a limited space. NEED OF STUDY 14-11-2022 Wani Aditya Balasaheb 6

  • 25. SUMMARY OF THE PROGRAMME 14-11-2022 Wani Aditya Balasaheb 25 ⮚ The present investigation aims “Micropropagation of Madagascar periwinkle (Catharanthus roseus)” and the related work were carried out in Plant Tissue Culture Laboratory. ⮚ Demand for the healthy planting material of Madagascar periwinkle is very high. ⮚ As this herb, is an important medicinal plant, it is becoming a vulnerable species due to its low seed germination percentage and poor seed viability. Productions of large numbers of Catharanthus roseus plants were possible through in vitro micro-propagation techniques. ⮚ Propagation of Madagascar periwinkle through tissue culture is reliable solution to produced disease and virus free planting material to the farmers. ⮚ In this study sterilization protocol were standardized. ⮚ Growth regulator’s play an important role on growth and development of Micropropagation of Madagascar periwinkle shoot culture.
