Allelopathic effects of Parthenium hysterophorus leaves on morphology and cytology of Trigonella foenum-graecum L.

摘要

The allelopathic effects of P. hysterophorus leaves on the morphology and cytology of T. foenum-graecum were investigated in Allahabad, Uttar Pradesh, India. Fresh P. hysterophorus leaves were chopped; incorporated in the soil at 50, 100, 150, 200, 250 and 300 gm; and allowed to decompose by watering for 7 days before T. foenum-graecum sowing. The lowest rate showed a stimulatory effect on plant height, number of branches per plant, length and breadth of leaves, pod number per plant and number of seeds per pod, while higher rates inhibited these parameters. Plants supplied with the decomposed leaves exhibited various frequencies of chromosomal abnormalities.
