Question

The water potential of a seed can be described by three components. Which are these components and how can they be explained by seed properties on a cellular basis

Answer 1

Components of water potential

Many different potentials affect the total water potential, and sum of these potentials determines the overall water potential and the direction of water flow:

    ÃŽÂ¨ = Ψ0 + Ψπ + Ψp + Ψs + Ψv + Ψm

where:

    * Ψ0 is the reference correction,

    * Ψπ is the solute potential,

    * Ψp is the pressure potential,

    * Ψs is the gravimetric component,

    * Ψv is the potential due to humidity, and

    * Ψm is the potential due to matrix effects (e.g., fluid cohesion and surface tension.)

Mainly Pressure potential , Solute potential and Matrix potential r considered.
