Allelopathic Potential

An extensive survey of floristic of native and invasive weed species was carried out during 2016 to 2019 in the semiarid agro ecosystem of Baramati Tahsil, Dist- Pune (M.S.). About 18 dominant invasive weeds such as Ageratum, Alternanthera, Croton., Xanthium, Parthenium and Tridax were encroaching the natives, becoming a serious threat to the major crops of this area such as wheat, sorghum, pearl millet, mung bean, pigeon pea, chillies and tomato. Amongst these Croton bonplandianus was highly dominant and wide spreading. Hence, its allelopathic potential was investigated. The allelopathic influence of leaf and root leachates as well as extracts of Croton bonplandianus Bail. was examined on seed germination of mung bean (Vigna radiata L.). The germination assay revealed that allelopathic potential and other factors are responsible for its dominance and successful invasion. The allelopathic influence of rhizosphere soil and its aqueous leachates indicated that both are responsible for inhibiting the seed germination and seedling growth of mungbean. Both the experiments have clearly confirmed the allelopathic potential of Croton bonplandianus. The HPTLC analyses confirmed the existence of a broad groups of allelochemicals like terpenoides, steroids, flavonoids, pungent and bitter essential oils and phenolics in its leaves and roots, which confirmed its allelopathic potential. Further characterization of above mentioned allelochemicals is in progress.

Germination And Growth

Etlingera coccinea, a native Borneon Zingiberaceae are found to exert allelopathic effect on some weed species. The objective of this study is to investigate the allelopathic effects of hexane (80%), methanol (80%), ethyl acetate (80%) extracts from the dried powder of both stem and leaf of E. coccinea on mung bean (Vigna radiata) and Siam weed (Chromolaena odorata). The phytochemical screening of both stem and leaf crude extracts elicited saponin, tannin, flavonoid, and terpenoid, which are targeted bioactive compounds for allelopathy. The allelopathic activity was assessed by evaluating their effects on seed germination and percentage of radicle and shoot growth. The results showed that both stem and leaf extracts have a suppressive effect on the mung bean development during in-vitro bioassay. The methanolic extracts of both stem and leaf showed the most significant suppression (100%) than other solvent extracts. In the pot experiment, the methanolic stem extracts suppressed the Siam weed’s germination by 57 ± 0.13% and the methanolic leaf extracts suppressed the growth by 46 ± 0.29%. The present study shows that E. coccinea methanolic extract has the potential as bio-herbicide.

Major Constraint ◽  
Voluntary Intake

Goats are an important component of the livelihoods of resource poor livestock keepers (RPLK) in Nepal. A major constraint is the poor health (and low economic value) of goats in the early part of the wet season, and this is partly brought about by the shortage of available forage in the dry season. Two invasive weeds (Eupatorium adenophorum, EA, and Chromolaena odorata, CO) now grow throughout Nepal. The plants grow year round, and so could be used as a source of forage, but their voluntary intake and perceived nutritive value by goats is low. If an appropriate means of treating EA and CO could be developed, their nutritive value may increase. EA and CO could then be included in the forage harvested for goats. The objective of this experiment was therefore to determine the effect on the nutritive value of EA and CO of either wilting or soaking these plants.

Invasive Weed

Buffalobur is a noxious and invasive weed species native to North America. The influence of environmental factors on seed germination and seedling emergence of buffalobur were evaluated in laboratory and greenhouse experiments. The germination of buffalobur seeds occurred at temperatures ranging from 12.5 to 45 C, with optimum germination attained between 25 and 35 C. Buffalobur seeds germinated equally well under both a 14-h photoperiod and continuous darkness; however, prolonged light exposure (≥ 16 h) significantly inhibited the seed germination. Buffalobur seed is rather tolerant to low water potential and high salt stress, as germination was 28 and 52% at osmotic potentials of −1.1 MPa and salinity level of 160 mM, respectively. Medium pH has no significant effect on seed germination; germination was greater than 95% over a broad pH range from 3 to 10. Seedling emergence was higher (85%) for seeds buried at a soil depth of 2 cm than for those placed on the soil surface (32%), but no seedlings emerged when burial depth reached 8 cm. Knowledge of germination biology of buffalobur obtained in this study will be useful in predicting the potential distribution area and developing effective management strategies for this species.
