Question

Some plants height stunting & some plants height increase, write down their reason.

Answer 1

Answer:

Stunting may be caused by viral, bacterial, fungal, or nematode (eelworm) infections and by noninfectious (abiotic) means including an excess or lack of water, imbalance of soil nutrients, excess light, chemical or mechanical injuries, insect or mite feeding, and too-deep planting.

Explanation:

Although being tall is advantageous in light competition, it entails costs for plants. As leaf height increases, plants need to invest biomass more than proportionately in the stem to support their own weight, which in turn reduces the fraction of leaf mass in the plant (Givnish, 1982; Niklas, 1992).
