It's utilised to preserve the plant material obtained fresh for a long time. The vasculum is painted white to reflect light and to make it easier to find because of the contrast with the green vegetation. A belt is attached to both ends, allowing it to be carried like a bag.
Secateur: It is used for cutting the twigs of shrubs, trees for Herbarium specimens.
Press for Plants: It's made up of two 30 cm × 45 cm wire guage frames . Three iron plates with two holes, one on each end, are installed at an equal distance on one side of the wire-gauge frame. Similarly, the other is equipped with three more plates. Six thin ropes or chains (three on each side) should be tightened at one end with the plates' holes on both sides.
5. The herbarium specimen on whose basis a new species is described for the first time is known as ?
a) Isotype b) Lectotype c) Holotype d) Neotype
Answer :- Holotype, the specimen designated by the orginal author. Isotype:- any duplicate specimen of the holotype. Lectotype: a specimen or illustration designated as the type when no holotype was indicated at the time of publication. A substitute specimen was selected under unusual circumstances (accidental fire, war) to replace the holotype specimen is referred to as Neotype.
6. Steps come first in the herbarium preparation?
a) poisoning b) deposition c) mounting d) collection
Answer:- Step 1. Collection :- The healthy plant specimens were collected, kept in metalic vasculum or polythene bags.
Step 2. Drying:- The collected plant material were pressed in newspapers, followed by field press to avoid the decaying of the plant material.
Step 3. Poisoning:- Mercuric chloride is used to prevent the growth of microbes. After this treatment, the plant specimens were again dried.
Step 4. Mounting, Stitching and labelling:- The completely dried plant specimens were glued and stitched on the herbarium sheets. Field data was entered.
Step 5. Deposition :- The sheets were arranged according to the Bentham and Hookers system Classification.
7. What is the standard size of Herbarium sheet?
a) 42 x 29cm b) 42 x 30cm c) 41x 30 cm d) 43 x 29cm
