There are a routine of factors that affectplant increase , include sufficient light source , water , dirt and filth nutrients . Overcrowding will affect plant outgrowth in many ways , including encouraging the development of diseases , halter yield and blossom production , provoke worm and pestilence problems and influencing the overall growth and development of a plant . Plants have a innate defense mechanism called allelopathy that is plan to prevent overcrowding and protect them from its consequences .
Overcrowding Root Crops
A pure example of the impact that overcrowding has on the growth of root vegetables is seen in the planting of radishes . Radish seed are so small that it would be virtually unimaginable to separate them and constitute a exclusive seminal fluid at the spacing urge by the seminal fluid company . This also put on to carrot . Once the seeds shoot and the seedling are sufficiently magnanimous , you must thin them in rules of order to provide the prominent and tidy seedling with the chance to grow and develop properly . When crops such as radishes and/or carrot are not thinned , there is no outer space for the root , which is the veg in this case , to grow and originate .
Allelopathy and Overcrowding
Allelopathy is limit as the chemical process that plant employ to foreclose other plants from germinate or acquire close to them . Alleopathy is designed to prevent overcrowding so that plants are levelheaded . Overcrowding can compromise the infinite that plants require for root growth . It can also lessen the amount of nutrients that any of the crowded plant can absorb from the soil , make developmental problem in all of the plant . Overcrowding can also allow improbable plant to forget sun from smaller plant , preventing photosynthesis and basically thirst the plants . Photosynthesis is the process through which plants change over lite energy into chemic energy , which is then stored in lucre bond .
Allelochemicals
Allelochemicals are chemical compound that one plant metal money turn to prevent another works metal money in the vicinity from encroaching on its space and overcrowding it . These chemical dissipate quickly , urinate them very in force as a rude weed killer . Allelochemicals are expel from works beginning , leaves , fruits and even from decaying flora matter , such as compost or mulch . Allelochemicals that are free from mulch are able-bodied to touch on the increase of blossom , fruit- and vegetable - producing industrial plant and trees and bush .
How Allelochemicals Work
There are several ways that allelochemicals act upon to kill the targeted plants . They can interfere with the activation of growth hormone or block protein synthesis . They can also inhibit cellular phone division in specific area of the roots , inhibiting root word increase and , by extension , overall works growth . They may also starve plants by foreclose photosynthesis . Without light , plant life can not exchange light push into the chemical energy that is stored as sugar . A plant without energy will die .
