Ageratina Adenophora

A study was conducted to investigate the effects of invasive weed Ageratina adenophora on the seed germination and seedling growth of Triticum aestivum, Brassica campestris and on weeds Ageratum conyzoides, Bidens pilosa, Galinsoga parviflora and Cyperus rotundus. The aqueous extracts of Ageratina plant’s part root, stem and leaf; and compost extract of Ageratina on different concentrations (control, 1, 2.5, 5 and 10%) were used to determine its effect on the seed germination, shoot and root length of Triticum aestivum, Brassica campestris and some common weed seeds under laboratory condition. The compost of A. adenophora at different doses viz. 0, 10, 20, 40 and 50g compost/kg soil was also applied to study the effect on the seed germination and seedling growth of B. campestris and T. aestivum and some weed seeds. The aqueous and compost extracts of Ageratina caused significant reduction in the seed germination and seedling length (shoot and root) which increased progressively on increasing the concentration of invasive plant's extract. The stem and leaf extracts of A. adenophora have more inhibitory effect on the germination percentage of winter crops as compared to root extract on the test crop seeds under study. In the compost of A. adenophora, the weeds showed more reduction in comparison to the crop plants B. campestris and T. aestivum. J. Biodivers. Conserv. Bioresour. Manag. 2018, 4(2): 11-20

Artemisia Dubia

Allelopathic effects of aqueous extract of different plant parts (root, stem and leaf) of Artemisia dubia on seed germination and seedling growth of two winter crops (Triticum aestivum and Brassica campestries, and some associated weeds (Bidens pilosa, Ageratum conyzoides, Galinsoga parviflora and Cyperus rotundus) have been investigated in the present study. Extracts of root, stem and leaves of Artemisia dubia showed significant reduction in germination and seedling growth of test crops and weeds. Germination of crop and weed seeds and growth of shoot and root were reduced significantly in test treatments in comparison to the control. The seed germination, shoot length and root length were low at higher concentration. Complete inhibition of seed germination of Ageratum conyzoides, Galinsoga parviflora and Cyperus rotundus at 5 and 10% leaf extract of A.dubia was observed. Allelopathic effects were more pronounced with leaf extract than root or stem extract in most cases.The result indicated difference in allelopathic effect on crop seed and weed seed at higher concentrations.

Allelopathic Potential

Allelopathic effects of Parthenium hysterophorus were studied on seed germination and seedling growth of Triticum aestivum, Oryza sativa, Glycine max and Cajanus cajan. The shade dried leaves of Parthenium hysterophorus were soaked in distilled water for 24 hours at room temperature to obtain aqueous extract and sterilized seeds were treated with 2%, 4%, 6%, 8% and 10% concentration of P. hysterophorus leaves aqueous extract. The germinated seeds were counted every day to observe mean germination time. It has been found that significant time is taken to germinate with increasing concentration. It has been also observed that germination percentage, root length, shoot length and seedling vigour value were reduced at >2% as compared to control. The 10 % aqueous extract showed the maximum inhibitory effect on seedling growth. In the present investigation, the leaves aqueous extract of P. hysterophorus had strong inhibiting effects on seed germination and seedling growth. It is necessary to keep this weed under check at the emerging stage at agro crop field so that crop growth constraint may be avoided

Artemisia Dubia

Allelopathic effects of aqueous extract of leaves of Parthenium hysterophorus were studied on seed germination and seedling growth of three cereal crops (Oryza sativa L., Zea mays L. and Triticum aestivum L.), three cultivated crucifers (Raphanus sativus L., Brassica campestris L. and Brassica oleracea L.) and two wild species of family Asteraceae (Artemisia dubia Wall ex. Besser and Ageratina adenophora (Spreng) King and HE Robins). Seed germination of all crucifer species was completely inhibited at >2% leaf extract of Parthenium hysterophorus but in other species, except maize, complete failure of seed germination was recorded only at >6% in Triticum aestivum and Ageratina adenophora; at 10% in Oryza sativa and Artemisia dubia. Seed germination of Zea mays was not completely inhibited but it was low at high concentration of the extract. The extract had strong inhibitory effect to root elongation of seedling in cereals and to shoot elongation in crucifers and wild Asteraceae. Leaves of Parthenium hysterophorus may be a source of natural weedicide against Ageratina adenophora which will help to control invasive plants.
