Mineral supply and growth

0% water only, 1%, 3%, 5%-inorganic fertilizer best nutrient supply, and growth

At 10% the inorganic fertilizer improves growth and in the case of crops the yield would also be better

When there is less than optimal nutrient supply there is stunted growth, inadequate supply of nutrients this is also associated with decreased plant productivity and fertility. When plants are nitrogen deficient the leaves die from the tip and turn brown.

Oversupply of nutrients also harms the plants and affects growth negatively. For instance, nitrogen is crucial to producing chlorophyll and absorbing light, but too much nitrogen in fertilizers can result in nitrate toxicity when the leaves and steams ‘burn’ and can also promote fungal diseases.

II. HORMONAL REGULATION OF GROWTH AND DEVELOPMENT (Week 2)

Terminal bud intact

Terminal bud removed and the mixture of lanolin+IAA (auxin) applied

Terminal bud removed

And lanolin applied

10) Auxin has an inhibitory effect on the growth of lateral buds, as auxin is required for apical dominance

11) Pinching the apical bud results in the lateral buds growing

12) Applying the auxin (lanolin+IAA) then inhibit the lateral bud growth again

13) Lanolin is the (control) in the experiment
