Abstract

Genomic assessment of the in vitro raised variations is necessary to protect the useful characteristics of the elite cultivars. Populus ciliata has significant potential among the commercially propagated tree species such as teak, Eucalyptus, red wood and radiata pine. Himalayan poplar occupies a unique and important position in the rural economy of India as it is a rare forest species ideal for successful intercultivation with agronomically important crops. Populus ciliata is a deciduous tree with sexually differentiated male and female plants, grown at an altitude of 1200-3500 m and largely distributed in temperate and subtemperate regions of the Himalaya.

Abstract

Genetic integrity of tissue culture-raised plantlets of broccoli cv. Solan green head from India was assessed using RAPD. First, highly efficient, reliable and highfrequency shoot regeneration was achieved in leaf (62.96%) and petiole (91.11%) explants on MS medium containing 4.5 mg/l BAP + 0.019 mg/l NAA, and 4.0 mg/l BAP and 0.5 mg/l NAA respectively. Maximum ischolar_maining ability (93.99%) with healthy and vigorous ischolar_mains was observed on MS medium containing 0.20 mg/l NAA. The regenerated plantlets with welldeveloped shoot and ischolar_main system were acclimatized successfully. For genetic stability studies, a total of 66 amplicons were amplified using 15 informative primers with a high degree of monomorphism (88.45%) across the mother plant and 20 randomly selected in vitro regenerated plantlets.

Abstract

We are in the midst of a global pandemic, the COVID-19. With no vaccine against the infection or medicines to treat the infected, the world is struggling to cope up with the increasing infections and casualties. It is recognized by everyone that the only option available to reduce the spread of the infection is to bring in lifestyle changes. Active participation by everyone is mandatory for success of this strategy. It is emphasized that the scientific community can play a very effective role in conveying this message across the entire population.

Abstract

The present policy of the Government asking regional electricity grids to absorb all the power generated by renewable power installations, and the thermal power stations to run at lower capacities than their installed values would not only force many thermal power plants to run at power levels much lower than their design values, but also constantly ramp up and down their outputs every day causing more wear and tear of the system. We suggest that the problem can be avoided by running the thermal power plants at their installed capacities, and use the surplus electricity to produce and store onsite hydrogen and oxygen. The stored hydrogen can be subsequently used not only to supplement coal in their own furnaces, but also for a variety of applications such as production of ammonia for fertilizers, as automobile fuel or for any other industrial applications. The ultrapure oxygen may be marketed for medical and other industrial applications.
