Improving Growth and Active Constituents of (Coriandrum sativum l.) Plant Using Some Natural Stimulants Under Different Climate Conditions.

Abstract

The present study was carried out at El-Baramoon Experimental Farm, Hort. Res. Institute, Agric. Res. Center, Ministry of Agric., during the two seasons of (2013 / 2014) and (2014 / 2015) to study the effect of sowing dates (Sept., Oct., Nov., Dec. and Jan.) and foliar application of some natural stimulants (Seaweeds extract, Moringa leaf extract, Salicylic acid and Chitosan) as well as their interaction on vegetative growth, fruit yield and essential oil of coriander (Coriandrum sativum L.) plant. The results showed that sowing coriander seeds in October resulted in significant increase in growth characters, fruit yield and essential oil composition compared with other sowing dates in both seasons. Foliar applications of some natural stimulants (Chitosan, followed by Moringa leaf extract then Salicylic acid) significantly affected all studied parameters compared to the treatments of seaweed extract and the control plant. Moreover, the interaction treatments indicated that the highest means values for most growth characters, fruit yield and essential oil productivity were recorded from plants sown in October and sprayed with Chitosan. Delayed sowing in December and January and spraying with Moringa leaf extract gave good production at cold temperature. The G.L.C. of essential oil revealed total of 11 compounds. The main compound was linalool which constitutes 79.8 % in October sowing date with Chitosan foliar application and the sowing date in January with Moringa leaf extract application was 78.3 %.These results showed that, it is possible to produce coriander plants under different climate conditions by using some natural stimulants. Fruits yield and active constituents under early and normal sowing dates could be improved by spraying plants with chitosan foliar application, while under delayed sowing dates spraying plants with moringa leaf extract.

The efficiency of salicylic acid and poultry manure on growth and volatile oil production of Coriandrum sativum L. plants

“…These results are in line with those found by Gahory et al (2022), Hekmat Massoud et al (2016), Said-Al Ahi et al (2014), and Hesami et al (2012), and Coriander, Talaat et al (2014) on khella, Abd El-Latif (2007 on borage, Abd on sweet pepper, Ghaly and Abd El-Sayed (2009) on guar and Ahmad et al (2023) on Pea plant.…”

Effect of Some Safety Growth Stimulants and Zinc Treatments on Growth, Seeds Yield, Chemical Constituents, Oil Productivity and Fixed Oil Constituents of Chia (Salvia Hispanica L.) Plant

“…citrata and Jamali et al (2015) on basil plants and Tadayyon (2017) on Guizotia abyssinica. Regarding the effect of chitosan, Orlita et al (2008) on Ruta graveolens and Massoud et al (2016) on Coriandrum sativum reported increases in essential oil productivity by chitosan treatments. Ibrahim and Helaly (2017) illustrated that, the better fixed oil production, chemical constituents of seeds and as well as trigonelline content in seeds could be obtained by spraying humic acid at 2 l/feddan level on fertilized fenugreek plants with NK at 75% of recommended rate.…”

Impact of Planting Dates and Organic Fertilization on Growth, Productivity and Essential Oil Components of Coriander (Corianderum sativum L) Plant.

“…1 (2023) SARA A. KAMAL et al maximum productivity of plants (Massoud et al, 2016). Climate changes will have farreaching consequences for agriculture that will disproportionally affect crop productivity.…”
