What are some good and bad results on irradiation being used on seeds
malfutka [58]

Explanation:

The effects of gamma radiation are investigated by studying plant germination, growth and development, and biochemical characteristics of maize. Maize dry seeds are exposed to a gamma source at doses ranging from 0.1 to 1 kGy. Our results show that the germination potential, expressed through the final germination percentage and the germination index, as well as the physiological parameters of maize seedlings (root and shoot lengths) decreased by increasing the irradiation dose. Moreover, plants derived from seeds exposed at higher doses did not survive more than 10 days. Biochemical differences based on photosynthetic pigment (chlorophyll a, chlorophyll b, carotenoids) content revealed an inversely proportional relationship to doses of exposure. Furthermore, the concentration of chlorophyll a was higher than chlorophyll b in both irradiated and non-irradiated seedlings. Electron spin resonance spectroscopy used to evaluate the amount of free radicals induced by gamma ray treatment demonstrates that the relative concentration of radiation-induced free radicals depends linearly on the absorbed

A new island formed by volcanic action may eventually become populated with biotic communities. describe the type of ecological
Katyanochek1 [597]

The type of ecological succession being described in the illustration is primary succession.

<h3>What is primary succession?</h3>

It is a form of succession that occurs when an area that has never been occupied by any living organism becomes exposed and eventually gets colonized by living organisms.

It is quite different from secondary succession which happens when an area that has been housing biotic communities before gets disrupted by a major disturbance.

A new island formed by volcanic action has never housed any biotic community before. Thus, only primary succession can occur there.
