Abstract:
... Rooting media were evaluated to identify problems contributing to poor rooting. Seven media combinations of coir and perlite were investigated, including two sources of coir (‘CG’ and ‘GS’). Final rooting results showed that the 2:1 (‘CG’ coir: perlite), with or without Osmocote® Start, and the 50:50 (‘GS’ coir: perlite) medium supported the best rooting results (19.49%, 19.79% and 17.11%, respect ...

Abstract:
... Phytohormones such as cytokinins, abscisic acid (ABA) and auxins play a vital role in plant development and regulatory processes. Their role within the plant is a focus for much research, with studies using recent advances in mass spectrometry performance allowing the quantification of low levels of phytohormones extracted from plant tissues. Despite these advances, external factors influencing th ...

... Knowledge of substrate particle size and shape is beneficial for reasons such as increasing product efficiency, ensuring specified standards, and maximizing plant growth. Classification of aggregate materials has long been analyzed on the basis of sieve analysis. Sieves work by separating aggregate materials by a particle’s 2nd smallest dimension (Allen, 1997). The material is then expressed as a ...
