Metabolites Liberated by Roots of White Pine (Pinus strobus L.) Seedlings

The seen and unseen world of the fallen tree.

“…Some of these compounds may be secreted from the roots to selectively promote growth of certain micro-organisms (Slankis andothers 1964, Smith 1969). Some fungi are capable of penetrating feeder roots to tap the nutrients within.…”

Effect of foliar spray of hormones on the rhizosphere mycoflora of leguminous weeds

“…Agnihotri 1 reported that increase in the exudation of amino acids and glutamine together with inerease in glucose and fructose and decrease in organic acids might be the reason for the significant population changes in the rhizosphere of wheat following foliar spray of urea. By applying 0402 on the leaves of white pine Slankis et al 19 reported more than 55 radioactive compounds in root excretions. It is understood therefore, that the chemicals applied on the leaves enter into various metabolic pathways of the plant and are excreted through the roots along with other compounds.…”

The Excretion of the β‐Carboline Alkaloid Harman in Passionfruit

“…The BaCO3 was collected, dried and the radioactivity estimated. Root culture experiments were adapted from Slankis et al (1964). The regenerated seedlings were grown in sterilized tap water changed every two weeks.…”
