Robusta And Arabica Coffee Plants

robusta and arabica coffee plants
Glance Coffee Plant
Coffee plant is an evergreen perennial dicotyledon wood owned by the family Rubiaceae. Due to grow to a height which is relatively large, is more accurately described as a coffee tree. Having a main vertical rod (orthotropic) and secondary, and tertiary horizontal branch, primary (plagiotropic).

Coffee Plant Growth and Development
Three to four years after the coffee is grown, sweet-smelling flowers grow in clusters in the axils of leaves coffee .. Fruit is produced only in the new network Coffea Arabica coffee plant is self-pollinating, while robusta coffee plant depends on cross-pollination. Approximately 6-8 weeks after each coffee flower is fertilized, cell division occurs and cherries remain as the head of a pin for a period of time depending on the climate. The ovaries will develop into drupes in a period of rapid growth that takes about 15 weeks after flowering .. During this time of the integument take the form of coffee beans After the end of a period of rapid growth integument and parchment are fully grown and will not grow. endosperm remains small until about 12 weeks after flowering .. At this time will suppress, consume, and replace the remnants integument integument is what constitutes the silverskin. The. endosperm will have totally fill the cavity created by the integument nineteen weeks after the current flowing white endosperm and humid, but it will get dry ingredients over the coming months coffee. During this time of the endosperm attracted more than seventy percent of the total photsynthesates produced by trees. The mesocarps will expand to form a sweet pulp that surrounds the coffee beans. cherry will change color from green to red approximately 30-35 weeks after flowing. See the Flash movie at Coffee Bean Development.
Coffee Plant Root System


Coffee tree roots may extend 20-25 km in total length (Malavolta, 195) and absorbing surfaces of trees ranging from 400-500 m 2 (Nutman) ,. There is a main vertical roots tap root and lateral roots that grow parallel to the ground. Tap roots extend no more than 30-45 cm below the soil surface. Four to eight axial roots may be encountered which often originate horizontally but pointing downwards. Lateral roots can extend 2 m from the trunk. Approximately 80-90% of the feeder roots in the first 20 cm of soil and 60-90 cm from the trunk of coffee (Mavolta, 195-196) ,. However Nutman stated that the greatest concentration is in the roots to a depth of 60 cm 30. The root system is highly influenced by the type of soil and mineral content of the soil. To be thick and strong, coffee roots require extensive supply of nitrogen, calcium and magnesium. During planting the main vertical Often roots are clipped to promote the horizontal growth of the roots, the which then have better access to water and added nutrients in the top soil. During the planting of the main vertical roots are often clipped to promote horizontal root growth, which then have a better access to water and add nutrients to the soil above.
Coffee Leaf
Elliptical leaves of the coffee tree, glossy, dark green, and waxy (. Coffee bean leaf area index is between 7 and 8 for superior coffee Malavolta, 195). The coffee plant has become the main source of oxygen in. the world over each hectare of coffee produces 86 pounds of oxygen per day, which is about half the production of the same area in the rainforest (source: Anacafe).
