Fair Test: Plant Propagation


Fair Test: Plant PropagationVersion en ligne Fair test basics for plant propagation par Jeorge Pascual 1 What is the main goal of a fair test in plant propagation experiments? a Prove all variables affect propagation b Show propagation success is random c Isolate the effect of one variable on propagation. d Test all variables at once 2 Which variable should typically be kept constant when comparing propagation methods? a Soil type b Propagating hormone used c Watering frequency d Light exposure 3 What is a control in a plant propagation fair test? a A treatment with no change in the variable tested b A random variation in conditions c A highly altered environment d A different species as benchmark 4 Why should seeds or cuttings come from the same parent plant in early trials? a To save time b To be easier to label c To reduce genetic variation d Because all parents are identical 5 What is a good way to structure replicated trials in propagation tests? a Multiple runs with the same conditions b Vary every factor each time c Randomize without replication d Only one trial is enough 6 How can randomization improve a plant propagation experiment? a Keeps all units identical b Allocates treatments to units randomly c Removes the need for a control d Manually biases outcomes 7 Which environmental factor is safest to vary when testing propagation methods? a Container size but not medium b Time of day c Pots’ color d Propagation medium (substrate) composition 8 What should be recorded to assess propagation success fairly? a Root formation rate and number of new plantlets b Color of leaves only c Species height after a year d Vegetative scent 9 Why is it important to randomize the position of pots in the growing area? a To complicate data collection b To keep plants stressed c To prevent micro-environment bias d To make watering harder 10 What is the role of a hypothesis in a fair propagation test? a Defines seed color b Lists all possible results c Predicts how one variable affects propagation d Determines pot size to use Feedback 1 A fair test changes only one factor at a time to reveal its true effect. 2 Constancy of identical factors (e.g., light) avoids confounding results. 3 Controls help compare against a baseline with no alteration. 4 Using a single parent minimizes genetic differences that affect outcomes. 5 Replication increases reliability and reduces random error. 6 Randomization minimizes systematic bias in treatment assignment. 7 Medium composition often influences rooting and can be isolated. 8 Quantifiable outcomes like rooting rate are essential. 9 Position randomness avoids location-based biases (light, drafts). 10 A test begins with a testable prediction about a single factor.
