The movement of materials(photoassimilate) from leaves to other part of tissues throughout the plant. Carbohydrates produced by plants in their leaves by photosynthesis - Non photosynthetic part of plant also require carbohydrate, organic and non-organic materials. Nutrients translocated : SOURCE (areas of supply/region of excess carbohydrate-mature leaves) TO SINK (areas of metabolism/region where carbohydrate is needed-roots, tubers, developing fruits, immature leaves.) How is translocation affected by drought? - Insufficient amount of water will affect the movement of solute from source to sink) ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],*photoassimilate is one of a number of biological compounds formed by assimilation using light-dependent reaction . TRANSLOCATION

Earliest method. Choosing individual plants that exhibit the best traits and saving their seeds to sow the following year.

Process of combining different varieties or species of organisms to create a hybrid . The pollen grains from a plant with desired characters are transferred to the stigmas of female flowers of other plant
