Native banana varieties possess a large number of agronomically superior traits and hence, have a great potential in the domestic as well as international market. Though, India is considered as home of bananas, not many varieties have been grown on commercial scale. Micropropagation, which offers a reliable tool for multiplication of plants, could be of(More)
Nicolau syndrome is an uncommon complication of intramuscular injection leading to variable degrees of necrosis of skin and the underlying tissues. We report here two cases of this syndrome. Our first case was a 25 year-old male who developed intense pain and purplish discoloration of the skin in the right hip after intramuscular diclofenac injection. The(More)
Bacopa monnieri (L.) Wettest. (Scrophulariaceae) is a well-known medicinal herb. In the Indian system of medicine it is known as Brahmi (Sanskrit) and Indian water hyssop. Methanolic extract of Bacopa monnieri and its isolated constituent Bacoside-A were screened for wound healing activity. Bacoside-A was screened for wound healing activity by excision,(More)
Carbon sources have been considered as one of the most important factors for in vitro multiplication of excised tissues. The type and concentration of sugars are known to influence the success of any in vitro protocol. In the present investigation, the effect of four carbon sources (glucose, fructose, mannitol, and sucrose) used to supplement Murashige and(More)
Panama wilt, a deadly disease of banana in general and Silk group in particular, is creating havoc worldwide. Infected planting material being a major mode of disease spread, production of disease free quality planting material is a must for area expansion. Micropropagation offers a viable solution for overcoming this problem. Though protocols for(More)
The commercial scale banana multiplication through micropropagation is concentrated mainly on the Cavendish group of bananas. Other varieties, though possess a wide array of desirable characters, have been conveniently neglected owing to their inherent problems such as difficult aseptic establishment, low multiplication rate, culture browning, difficult(More)
Mass multiplication of non-Cavendish group of bananas has been limited due to non availability of reliable multiplication protocol and higher cost of production. The process of root induction and hardening are considered to be the most capital and labour intensive activities in micropropagation of any species. Carbon sources being one of the prime(More)
A number of factors are known to influence the aseptic culture multiplication, rooting and subsequent hardening in banana. Study of these factors would not only improve the in vitro response but also help in increasing the understanding of its basis. During present investigation, in vitro culture proliferation and root induction response in Silk banana as(More)
Silk Banana is amongst the most popular groups of bananas grown in different parts of the world. However, the commercial scale cultivation requires identification of superior genotypes with desirable attributes including growth, yield, quality and resistance to Panama wilt disease which is a major concern. Panama disease caused by the fungus Fusarium(More)
Banana, one of the major staple food crops of the world, flowers round the year irrespective of the season. It gives the decisive flexibility to the grower for planning orchard operations as well as exploring the best marketing opportunities for the produce well in advance. Being a heavy feeder of nutrients and water, these inputs are critical to the(More)
