ABA (Abscisic acid) is the chemical that acts as an aid for mechanical harvesting.
Abscisic acid (ABA) is a key hormone involved in tuning responses to several abiotic stresses and also has remarkable impacts on plant defense against various pathogens.
It acts as plant growth regulator, especially in seed maturation, seed dormancy, adaptive responsive to biotic and abiotic stresses and leaf and bud absicission.
Mechanical harvesting systems are designed to achieve the mass removal of the commodity during the harvesting season at once.

Botanical name of Mango ginger is Curcuma amada.
Mango ginger is an annual plant that belongs to Zingiberaceae family.
It has been cultivated throughout the world and is used for food flaovouring. It contains cic-trans hydrocimene, ocimene and myrcene.

Percent of outcrossing in autogamous crops is < 5%.
Autogamous plants are such plants in which pollination of a flower occurs by its own pollen.
Outcrossing, also known as allogamy or xenogamy, is the transfer of gametes from one individual to another, genetically different individual. Thus, percentage of outcrossing is very less in case of autogamous plants.

Pollination behavior of Robusta coffee is Cross pollinated.
The Robusta coffee plant depends on cross pollination. Robusta requires cross-pollination by wind and insects. The main pollinators of coffee flowers are different kinds of bees.
