0: Germination, vegetative propagation 00: Dry seed (11–12% moisture content), beige color if parchment present or bluish-green if parchment and silver skin removed. Cutting (orthotropic, mononodal, 60 mm long, two half trimmed leaves). Stump with bulky nodes and no buds visible 01
It is a measure of germination time course and is usually expressed as a percentage, e.g., an 85% germination rate indicates that about 85 out of 100 seeds will probably germinate under proper conditions over the germination period given. Seed germination rate is determined by the seed genetic composition, morphological features and ...
Seeds were used as dice in games of chance that were common in eastern tribes. It is likely that indigenous community members carved patterns on coffeetree seeds used in ceremonial dice games, which also served to scarify the seeds and prepare them for germination. [29] The seeds were also used in jewelry.
True dormancy or inherent (or innate) dormancy is caused by conditions within the seed that prevent germination even if the conditions are favorable. [7] Imposed dormancy is caused by the external conditions that remain unsuitable for germination [8] Seed dormancy can be divided into two major categories based on what part of the seed produces dormancy: exogenous and endogenous.

A coffee bean is a seed from the Coffea plant and the source for coffee. It is the pit inside the red or purple fruit. This fruit is often referred to as a coffee cherry, and like the cherry, it is a fruit with a pit. Even though the coffee beans are not technically beans, they are referred to as such because of their resemblance to true beans ...
The coffee cherry has the fruit or pulp removed leaving the seed or bean which is then dried. While all green coffee is processed, the method that is used varies and can have a significant effect on the flavor of roasted and brewed coffee. Coffee production is a major source of income for 12.5 million households, most in developing countries. [1]
The polycyclic disease cycle of Colletotrichum kahawae is heavily dependent on rain/water for conidial production, dispersion, germination and infection. The timing of infection is regulated by the seasons and rainfall. Coffee growing regions of Africa receive two seasons of rain: long rains and short rains with relatively dry weather in between.
Norman C. Deno (February 15, 1921 – September 22, 2017) was an American chemist and plant scientist.He was a professor of chemistry at Penn State University and is known as one of the foremost researchers in seed germination theory.
