Seed Priming Based on Iodine and Selenium in Tomato Crop

These flashcards cover key concepts and findings from the research on the influence of iodine and selenium on the nutraceutical quality of tomato crops.

What is the main objective of the research on seed priming using KIO3 and Na2SeO3 in tomatoes?

To evaluate the nutraceutical quality of tomato fruits and leaves.

What essential roles do iodine (I) and selenium (Se) play in human health?

They are related to the proper functioning of the thyroid gland and act as antioxidants and antiproliferatives.

What negative effect was noted with the application of KIO3 and Na2SeO3 on tomato fruit compounds?

Vitamin C content was negatively affected.

How does seed imbibition affect the germination process?

It improves uniformity and germination percentage by stimulating pre-germination metabolic processes.

What are the main non-enzymatic antioxidant compounds measured in tomato fruits?

Lycopene, β-carotene, flavonoids, and vitamin C.

What effect does KIO3 have on the chlorophyll-a content in tomato leaves?

KIO3 increases the phenol and chlorophyll-a contents of leaves.

How does Na2SeO3 affect the GSH content and GPX activity in tomatoes?

Na2SeO3 favors GSH content and GPX activity in tomato fruits and leaves.

What is the significance of the 52-factorial design used in the research?

It allows the evaluation of various interactions between different KIO3 and Na2SeO3 concentrations.

What was a significant finding regarding the antioxidant capacity of hydrophilic compounds by DPPH?

It significantly increased in tomato leaves with Na2SeO3 treatments.

What method was used to prepare KIO3 and Na2SeO3 treatments for the tomato seeds?

A stock solution was prepared for each with specific concentrations and subsequently diluted for treatment use.
