Growth and Development of Horticultural Crops (1+1)

Introduction

• Plant needs an effective transport system for translocation of their photoassimilates from the area of synthesis (source) to area of utilization (sink).
  
• Every plants needs an effective transport system for the translocation of their photoassimilates from the areas of synthesis(source) to areas of utilization(sink).
  
• For instance during germination, stored assimilates in the seed is mobilized and moved to active meristems for leaf, stem and root development and soon the seedlings become autotrophic.
  
• Assimilates produced by green tissue is translocated throughout the plant for growth, development, storage and maintenance.
  
• The division of assimilates among these process termed partitioning determines the crop production.
  
• The partitioning of assimilates and inorganic nutrients can affect both the efficiency of phloem transport, dry matter production and the partition of matter in the harvest.
• In plant growth & development, materials are moved from source to sink, primarily through xylem & phloem.
1. Assimilates produced by green tissues is translocated throughout plant for growth, development, storage and cell maintenance .The division of assimilates among these process is termed as partitioning
2. It determine the dry matter production and productivity of crop
