Much of the first modern blackberry variety development was done in America, beginning with Judge Logan of California in 1880, and the release and introduction of the Loganberry.
A modified form of the thin-layer chromatography (TLC) method described by farnsworth and Euler (1962) is to be used. One gramme of the extract will be treated with 40 per cent calcium hydroxide until the extract is distinctly alkaline to litmus paper, and then extract twice with 10ml portions of chloroform. The extracts are to be combined and concentrated in vacuo to about 5ml. The chloroform extract is then spotted on thin-layer plates. Four different solvent systems (of widely varying polarity) are to be used to develop each plant extract. The presence of alkaloids in the developed chromotograms will therefore be detected by spraying the chromatograms with freshly prepared Dragendorff's spray reagent.
Different kinds of climatic calamities and sometimes artificial electrical damages cause power supply interruptions and blackouts. For these reasons, plant owners have sought out financial insurance for time loss and machinery damage. They have also installed backup electric supplying equipment to beat emergency. However, simply installing an added power generator may not solve the problem permanently and protect against climatic threats. Testing the backup power mechanism is important along with maintaining it to run the plants operations smoothly. A large number of managers are still not aware of the problems of their electrical backup systems and hence work with underperforming machines. Loadbank testing can help in finding the health of the backup system.
Summer adds colour and beauty to a garden because it is time for blossoms. It also means more heat and high humidity. Therefore, germination of the seeds becomes faster in the humid and warm soil. Bright indirect light usually is sufficient to encourage good flowering.
