 It converts the root into a source

2. Plant spacing in vegetable cultivation influences ______________

 Seed germination

 Light interception and competition

 Only pest incidence

 Only yield

3. Which statement accurately distinguishes a corm from other underground modified stems?

 A corm is an enlarged fleshy root with no nodes or buds

 A corm is identical to a bulb but lacks fleshy scales

 A corm is a horizontally growing stem that produces roots and shoots from nodes

 A corm is a solid, swollen underground stem with a basal plate, covered by papery sheaths, and bears distinct nodes and buds

4. Which of the following best defines physiological maturity?

 The point at which maximum dry weight and developmental completion are attained, regardless of harvest suitability

 The stage when chlorophyll content is highest in leaves

 The beginning of flower initiation in biennial crops

 The stage when the fruit or vegetable becomes ready for harvest for fresh market

5. Which activity is the primary focus of nursery management?

 Propagation and care of seedlings before transplanting

 Grading and packaging of mature vegetables
