Agricultural biodiversity is conserved:
1. in ex-situ locations commonly in the form of gene banks
2. in ex-situ locations commonly in botanical gardens
3. in in-situ locations such as biosphere reserves
4. in in-situ locations in agricultural institute fields
The first National Park established in India, the place where project tiger was started in 1972, is in:
1. | Madhya Pradesh | 2. | Kerala |
3. | West Bengal | 4. | Uttarakhand |
Recalcitrant seeds are:
1. seeds that do not survive drying and freezing during ex-situ conservation
2. seeds that can resist the effects of drying or temperatures less than 10 °C
3. can be stored for long periods
4. terminator seeds
The reasons to store seeds in a seed bank include all except:
1. To have available the genes that plant breeders need to increase yield, disease resistance, drought tolerance, nutritional quality, taste, etc. of crops.
2. To forestall loss of genetic diversity in rare plant species in an effort to conserve biodiversity ex-situ.
3. To preserve the historical and cultural value of plants not grown now.
4. To guard against biopiracy by limiting the use of seeds only in certain areas.
