Although annual plants die after one season, not all annual plants truly lack overlapping generations. Many annual plants have seed banks containing dormant seeds that remain dormant for at least one year. This makes overlapping generations possible in annual plants. [6] N.B domestication of annual plants has led to a reduction of seed dormancy ...
Modern seed sizes range from 0.0001 mg in orchid seeds to 42 kilograms (92 lb 10 oz) in double coconuts. [7] [2] Larger seeds have larger quantities of metabolic reserves in their embryo and endosperm available for the seedling [8] than smaller seeds, and often aid establishment under low resource availability.

The Global Crop Diversity Trust is an independent international organisation which exists to ensure the conservation and availability of crop diversity for food security worldwide. It was established through a partnership between the United Nations Food and Agriculture Organization (FAO) and CGIAR acting through Bioversity International. [25]
Banana plants are among the largest extant herbaceous plants, some reaching up to 9 m (30 ft) in height or 18 m (59 ft) in the case of Musa ingens.The large herb is composed of a modified underground stem (), a false trunk or pseudostem formed by the basal parts of tightly rolled leaves, a network of roots, and a large flower spike.
Plants were independently cultivated in at least 11 regions of the world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output. As of 2021, small farms produce about one-third of the world's food, but large farms are prevalent. [2]
Research has determined that plants can recognize each other's root systems and differentiate between a clone, a plant grown from the same mother plants seeds, and other species. Based on the root secretions, also called exudates, plants can make this determination. [ 47 ]
Intercropping is a multiple cropping practice that involves the cultivation of two or more crops simultaneously on the same field, a form of polyculture. [1] [2] The most common goal of intercropping is to produce a greater yield on a given piece of land by making use of resources or ecological processes that would otherwise not be utilized by a single crop.
Plant breeders also manipulate their subjects to hybridize in order to optimize their hardiness, appearance, or whatever desired traits they want to select for. [1] This type of hybridization has been particularly impactful for the production of many crop species, including but not limited to: certain types of rice, corn, wheat, barley, and rye.
