“…In addition, it is accepted that high NO donor concentrations may induce detoxification responses while lower concentrations might more accurately reflect its role as a signalling molecule (Wink and Mitchel, 1998;Beligni and Lamattina, 1999). Nayanakantha et al (2014) demonstrated that application of 50ml of SNP (at 50-500μM) into polybagged rubber seedlings greatly improved the root and growth characteristics under glass house conditions.…”

Shoot die-back condition has been observed in young-budded rubber plants especially under hot and dry weather conditions. This is partly attributed failure of the root system. Therefore, it is imperative to find ways to improve the root system while enhancing other growth attributes of polybagged rubber seedlings. Nitric oxide (NO) functions as a signaling molecule as well as a phytohormone in numerous physiological processes in plants from seed germination up to senescence. In the present study, the effect of sodium nitroprusside (SNP) as a NO donor on the root architecture and growth characteristics of polybagged rubber seedlings were investigated. Seven days old rubber seedlings were soaked in 200 µM and 500 µM solutions of SNP for 6 hours and 24 hours respectively prior to transplanting in polybags. Mock treated seedlings were soaked in water. Pretreatment with SNP greatly improved the root architecture of rubber seedlings by increasing the number and the length of lateral roots and the dry weight of roots while enhancing other growth parameters viz., stem diameter, shoot height and dry weight, leaf area and chlorophyll content in dose and time-dependant manner. Pretreatment with SNP at 500 μM for 6 hrs was found to be more effective for overall growth improvement in rubber seedlings. The improved growth characteristics of rubber seedlings could be attributed to the beneficial effect of SNP as a NO donor in modifying phytohormone signalling pathways, enhancing antioxidant enzyme activity, increase in nutrient uptake and effective allocation of photoassimilates.

“…Sphagnaticola species have antimicrobial, insecticidal, larvicidal and trypanosomicidal properties and are used for medicinal purposes (Huang et al 2006;Maldini et al 2009;Toppo et al 2013) and as a decorative ground cover in many parts of the world (Wagner et al 1990;Macanawai 2013). It is also used as a cover crop in rubber and tea plantations to control soil erosion in Asia (Nayanakantha 2007). Furthermore, it is used for ground cover in Middle Eastern countries, which helps stabilize the soil and prevent it from moving due to wind.…”

Allelopathic effects of the invasive plant Wedelia (Sphagneticola trilobata L.) aqueous extract on common beans (Phaseolus vulgaris L.)

Sphagneticola trilobata (L.) Pruski is an alien invasive weed with aggressive growth habits, environmental stress tolerance, and the ability to synthesize allelochemicals. However, in many parts of the world, this plant is still recommended for use in composting, phytoremediation, and as an ornamental ground cover in gardens. The present study investigated the allelopathic effect of S. trilobata on the seed germination, growth and yield of Phaseolus vulgaris L. To analyze the allelopathic effects of S. trilobata on P. vulgaris seed germination, hundred seeds of P. vulgaris were exposed to different concentrations of the aqueous extracts of fresh and dry S. trilobata (2.5×102, 5.0×102 and 7.5×102 g/L) in Petri dishes for five days. The impact of S. trilobata aqueous extract on the growth and yield of P. vulgaris was also studied with seedlings planted in a compost soil mixture. Results of the study suggested negative impacts of S. trilobata extracts on P. vulgaris seed germination, growth and yield. P. vulgaris seed germination was significantly lower in the treatments than in the control (p<0.05). Further, P. vulgaris plants treated with fresh plant extracts at 5.0×102 and 7.5×102 g/L concentrations had significantly lower shoot height, growth rate, leaf area, fresh shoot weight, dry shoot weight, root length, pod length and yield (p<0.05) than controls. From the results of the study, it can be concluded that S. trilobata aqueous extracts have a dose-dependent allelopathic effect on P. vulgaris seed germination, growth, and yield and among the dry and fresh plant extracts, fresh plant aqueous extracts have a more significant allelopathic impact. As S. trilobata contains water-soluble allelochemical, it should not be used in biofertilizer production, phytoremediation, or as live mulch.
