Allelopathic Effect of Root and Leaf Lechates of Selected Tree Species on the Growth of Pulses | Chapter 6 | Current Research Progress in Agricultural Sciences Vol. 9

The present experiment was carried out study the effect of teak, eucalyptus and casuarina tree leaf and root leachates on the growth of green gram, black gram, chickpea and cowpea. Results were affected significantly by tested parameters. There were both stimulatory and inhibitory effects were seen on the crop growth by the tree leachates. The inhibitory effect of leachates was greater during the early stages of crop growth (15 DAS) and in later stages, the effect was reduced. And some of the parameters show stimulatory effects at later stages.

Investigating the Allelotoxic Activity of Eucalyptus rostrata Schlecht. on Seed Germination and Seedling Growth of Chenopodium album L. and Portulaca oleracea L. | Chapter 11 | New Visions in Biological Science Vol. 6

 A range of allelopathic compounds have been found in Eucalyptus rostrata. Two noxious weeds, Chenopodium album and Portulaca oleracea, were studied for their allelopathic effect of Eucalyptus rostrata leaf (ERLAE) and bark (ERBAE) aqueous extracts on seed germination and seedling growth. Depending on the extract type and recipient species, the biological action of the two types of extracts on germination efficiency differs. The extracts had the following effect on the two weeds: ERLAE > ERBAE, and the action in C. album was practically as effective and substantial as it was in P. oleracea. The current study's findings suggest that the presence of allelochemicals in the aqueous extracts causes a slower rate of cell division and elongation, which results in shorter plumule and radical lengths. Finally, the findings of this study may help to solve the problem of excessive use of synthetic herbicides by applying and testing a variety of promising medicinal plants rich in allelochemicals, such as E. rostrata.
