Which one combination of plant growth regulators are used for feminising effect in cucurbits?
1 Auxins $>$ Ethylene $>$ Cytokinins
2 Gibberellins $>$ Auxins $>$ Cytokinins
3 Ethylene $>$ Gibberellins $>$ Auxin
4 Auxin + Gibberellins $=1$
Explanation:
A Auxins, Ethylene and Cytokinins phytohormone are used for sex expression inducing formation of more female flower in place of male flower in cucurbits. Auxins is more effective to induce feminizing effect in cucurbits.

The chemical nature of gibberellins is that they are
1 Acidic
2 Alkaline
3 Proteinaceous
4 Amines
Explanation:
A Chemical nature of gibberellins are acidic. Gibberellins are plant growth regulators that facilitate cell elongation, help the plants to grow taller. Gibberellin was discovered by E. Kurosawa in 1926 while investigating foolish seeding (balance) disease. I was caused by a fungus Gibberella fujikuroi.

Green potatoes are toxic due to
1 Phytoalexins
2 Solanine
3 Triazine
4 Hormones
Explanation:
B Potato some time becomes green which may indicate high levels of a potentially toxic compound which is called solanine which is exposed after the vegetable is exposed in the light solanine is also present in the sprout, root and leaves of a potato. The substance is a neutering if a person eats solanine. It causes headaches, diarrhoea, stomach cramp and nausea.

An example of mitogen is
1 cytokinin
2 glucose
3 glycerol
4 fructose
Explanation:
A An example of mitogen is cytokinin. Any agent that stimulates cell division is called mitogen. Mitogens are non- specific stimulants of immune cells.Mitogens are signals that act from outside the cell to induce mitosis and cell division.
