Abstract
Coriander (Coriandrum sativum L.) is one of the most important annual spice and medicinal herbplant. It is an open pollinated crop and honeybees are effective pollinators for open pollinated crops because of a lot of nectar and pollens are available on the flowers of Coriandrum sativum. An experiment was conducted to evaluate the effect of honeybees pollination on Coriandrum sativum seed yield and yield related parameters at Sinana Agricultural Research center at on-station. The study had three experiment; these includes plots caged with honeybees (T1), plots caged without honeybees (T2) and open pollinated plots (T3). All collected data were analyzed using One-way-Analysis of Variance (ANOVA). There were no significant different (P>0.05) on Date of blooming, Date of flowering,, Primary and secondary branches among the three treatments. Whereas, there were a significant difference (P<0.05) on Flowering period, shading time, Number of capsule, Thousand kernel weight and total seed yield per hector. The result also revealed that about 29.70% of seed yield advantage of Coriandrum sativum pollinated by honeybees over control/un pollinated by any insect. From this result it was concluded that visits of honeybees at flowering time of Coriandrum sativum have very helpful in increasing seed yield and yield related components of this crop.
Highlights
Pollination is an essential biological process in higher plant reproduction that involves the transfer of pollen to the female sexual organs of flowers [1]
Plots caged with honeybees the highest Thousand kernel weight (TKW) (3.05 g), whereas plots caged without honeybees had the lowest TKW (2.16 g)
The result revealed that mode of pollination and pollinators had a significant effect on the total seed yield of Coriandrum sativum L per hector
Summary
Pollination is an essential biological process in higher plant reproduction that involves the transfer of pollen to the female sexual organs of flowers [1]. Pollination carried out by animals is considered an important ecosystem service with 35% of the plants cultivated in the world benefitting from this interaction [2]. Among the various pollinating agents, insects played a major role. It is known that honeybees (Apismellifera L.) play an important role in pollination of some cultivated plants, notably allogamous species for which cross pollination is essential. Cross pollination of entomophilous crops by honeybees is considered as one of the effective and cheapest method for triggering the crop yield both qualitatively and quantitatively. Being the pollination service provider bees contribute handsomely in enhancing the productivity and production of cross pollinated crops through efficient pollination in an inconspicuous and ilentmanner [5, 6]
