1. Which elements play a role in regulation of osmotic processes?
a. Potassium
b. Calcium
c. Iron
d. Magnesium
e. Sodium
f. Boron
2. Which are the most important micro-elements in plant life?
a. Iron
b. Magnesium
c. Boron
d. Nickel
e. Zinc
f. Selenium
3. What does the Law of Liebig declare?
a. Each nutrient should be present in an equal amount for the optimal plant development.
b. Microelements are not effective without the presence of macroelements.
c. Plant production is determined basically by the element present in the lowest quantity
4. What does the Law of Mitscherlich declare?
a. Plant reaction decreases as the circumstances become better.
b. As response to nutrient supply is following an optimum power, overdosage is also dangerous.
c. Dosage of nutrient should overcome a minimum level for reaching its useful effect.
5. Which data are necessary for determining the nutrient need of the plant to a unit surface (kg/ha)?
Need of nutrient= Specific nutrient content x fresh yield
Need of nutrient = Need of the plant + corrections based on soil –other corrections
Need of nutrient = Nutrient content in soil+ dry yield – correction factors
6. What is the specific nutrient content?
a. Proportion of individual elements in soil compared to the total element content in mg/kg.
b. Plant dry mass multiplied by the atomic mass of the given element (%).
c. Amount of the element extracted from the soil by unit yield of the plant (kg/t)
7. What kind of groupings are there in the case of fertilizers?
a. aggregate
b. nutrient content
c. size of granules
d. nitrogen content
e. origin
f. pH value
8. Which medicinal plant species have a high nutrient demand?
a. peppermint
b. basil
c. savory
d. hairy mullein
e. dill
f. caraway
9. Which statement is not right?
a. Chamomile is salt tolerant, because the strong osmotic potential of the roots enables water uptake even from salty soils.
b. Chamomile prefers salty soils because it can develop bigger leaves and more flowers here.
c. Chamomile prefers good soils because root meristem dyes quickly in salty soils.
d. Chamomile is able to propagate itself on salty soils because of lack of concurrent species.
10. Which factors and processes may be influenced by the nutrient supply?
a. Speed of plant development
b. Disease tolerance
c. Drug yield
d. Accumulation of active ingredients
e. Frost tolerance
f. Seed setting and ripening
11. What are the known connections between the yield of active compounds, concentration of active compounds and plant biomass?
a. logarithmic, linear and/or power functions
b. linear, power and polynomial functions
c. according to the negative correlation coefficient
d. sinus or tangent functions
12. Which statement is not right?
a. Composition of active ingredients is influenced by the nutrient supply often only indirectly.
b. Accumulation of active ingredients follows an optimum function influenced by nutrient supply.
c. Production of effective materials is usually higher in poor soils and/or stressed environment.
d. Assuring an optimal development of the plant contributes to the profitability of production of active compounds.
