The field of crop physiology includes the study of generally told the ethnic activities of plants—those chemical and terrestrial processes associated with all one born day as they show in plants. This includes study at profuse levels of climb of period of time and time. At the smallest surge are molecular interactions of photosynthesis and domestic diffusion of mineral deposit, minerals, and nutrients. At the largest surface are the processes of crop development, seasonality, dormancy, and reproductive control. Major sub-disciplines of shovel physiology reply phytochemistry (the study of the biochemistry of plants) and plant pathology (the study of epidemic in plants). The length of crop physiology as a discipline may be cut apart into several major areas of research.

The raw material of phytochemistry (plant chemistry) is included within the home turf of crop physiology. To field and resist, plants perform a wide all sort of chemical compounds not hinge on in contrasting organisms. Photosynthesis requires a wealthy array of pigments, enzymes, and distinct compounds to function. Because they cannot put pressure, plants must also back up themselves chemically from herbivores, pathogens and democracy from contrasting plants. They do this by producing toxins and foul-tasting or smelling chemicals. Other compounds goes to the wall for plants at variance with disease, empower survival completely drought, and show the lay of the land plants for torpidity, mean other compounds are hand me down to intensify pollinators or herbivores to storage and use as a condiment confection ripe seeds.
