“…It has been suggested that smoke can possibly be used in promoting the growth of horticulture and vegetable crops (Brown and Van Staden, 1998;Light and Van Staden, 2004). Particularly in vegetable crop production, maximum yield is achieved when there is a better emergence and stand establishment of the seedlings (Grassbaugh and Bennett, 1998). Staggered emergence results in seedlings of different sizes, which can develop into a heterogeneous crop (Bennett et al, 1992).…”

The ecologic significance of smoke-related seed germination is now well recognized. Consequently, smoke solutions and a pure butenolide, the active compound from smoke that stimulates germination of a number of plant species, show great potential for enhancing the growth of vegetable crops. Achieving maximum production and better and faster growth of the seedlings has always been a priority for vegetable growers. This study therefore highlights the effects of foliar application of smoke-water and a butenolide on seedling growth of okra [Abelmoschus esculentus (L.) Moench] and tomato (Lycopersicon esculentum Mill.). Treating okra seedlings with smoke-water (1:500 v/v) showed a significant (P < 0.05) increase in shoot/root length, shoot fresh/dry weight, number of leaves, total leaf area, and stem thickness compared with the control treatment. Treatment of okra seedlings with smoke-water significantly (P < 0.05) increased the absolute growth rate (AGR) per week. However, the seedling vigor index (SVI) did not improve as a result of no change in root fresh weight. On the other hand, foliar application of smoke-water and butenolide showed a pronounced effect on the seedling growth of tomato. Most of the growth parameters examined for both the treatments were significantly (P < 0.05) increased, resulting in a significantly (P < 0.05) higher SVI and AGR than the control. This study indicates that the foliar application of smoke-water or butenolide may be a useful and inexpensive technique for enhancing seedling growth of vegetable crops.

“…The major factors affecting plantlet establishment are seed health and vigour, plantlet quality and health, and the environmental conditions under which the transplantation is performed, namely abiotic and biotic stresses. Implementation of the best conditions at the transplanting stage and adjustment of agrotechniques enable the genetic potential of the seed to be realized (Grassbaugh and Bennett, 1998).…”

“…Vegetable growers need more uniformity and precise prediction of the emergence and crop stand (Pervez et al, 2009). Similarly, high yield of the vegetable crops can only be obtained with high stand establishment of seedlings so that they can compete with the environment and can produce best plantation (Grassbaugh and Bennett, 1998). Crops lacking a good stand show reduced efficacy of other agronomic practices and usually such inputs can never compensate for the negative impact of a poor stand.…”

Polyamines are low molecular weight organic compounds involved in diverse range of biological processes in all living organisms. Seed priming is a technique that improves seed performance by rapid and uniform germination with normal and vigorous seedlings. A laboratory study was performed to explore the benefits of seed priming with polyamines on seed germination and seedling growth of hot pepper (Capsicum annuum L.) Hot pepper seeds were primed in aerated solution of putrescine, spermine, or spermidine (25, 50, 75, and 100 mM) for 48 h at 25 ± 2 °C. Significant results (P < 0.05) were observed for different attributes of seed germination and early seedling growth. Polyamines priming resulted in earlier and synchronized germination via improving final germination percentage, time to 50% germination, mean germination time, germination energy, germination speed and germination index compared with control. Improvement in shoot and root length, seedling fresh and dry weight, seedling growth rate and seedling vigor index was clearly indicative of positive effects of seed priming with polyamines. Out of all polyamines, putrescine proved to be better at low concentrations (i.e. 25 and 50 mM) for most of the traits related to seed emergence and seedling growth.
