Variation in biomass production of sunflower (Helianthus annuus) plants under the influence of Lemongrass (Cymbopogon erectus) extract

Öz

Plant extract is being used for crop yield and biomass enhancement since long time. Using plants extract for the enhancement of growth of other plant is a worthwhile strategy so as to enhance crop yield and crop biomass. Current study is an attempt to increase growth in sunflower plants using lemongrass foliar extract. For this purpose, various trials based on computer modeling have conducted. Pot experiment of sunflower plants has performed in greenhouse conditions that have irrigated by different concentrations of lemongrass extract. Results show that lower concentrations produced significant gain in biomass of crop i.e. greater fresh and dry weight was achieved by 1% samples (7.4±0.8mg and 2.0±0.3mg respectively) while lowest fresh and dry weight attained by 3% samples (2.5±0.2mg and 1.1±0.1mg respectively). Absolute growth rate (AGR) and Relative growth rate (RGR) of the plants are obtained in sequential order of treatment. Control, 0.5% and 2% samples form close linear fit to the model while 0.5% samples produce long tailed positive correlation fit whereas 3% samples are negatively fitted to the model. CDF model produce closely fitted relationship of 1% and control samples while 3% samples negatively corresponded to normal fit. Therefore, current study suggests promoting an efficient agriculture strategy that would be helpful in biomass gain of the crops to sequester carbon and effectively take part in climate mitigation.

Limon otu (Cymbopogon erectus) ekstresinin etkisi altında ayçiçeği (Helianthus annuus) bitkilerinin biyokütle üretiminde varyasyon

Öz

Bitki özütü, uzun süredir ürün verimi ve biyokütle arttırımı için kullanılmaktadır. Bitki ekstraktının diğer bitkilerin büyümesini arttırmak için kullanılması, mahsul verimini ve bitki biyokütlesini arttırmak için değerli bir stratejidir. Mevcut çalışma limon yaprakçık özü kullanarak ayçiçeği bitkilerinde büyümeyi artırma girişimidir. Bu amaçla bilgisayar modellemesine dayalı çeşitli denemeler yapılmıştır. Ayçiçeği bitkilerinin pot deneyi, farklı konsantrasyonlarda limon otu ekstresi ile sulanan sera koşullarında gerçekleştirilmiştir. Sonuçlar, daha düşük konsantrasyonların mahsul biyokütlesinde önemli bir kazanç sağladığını, yani daha yüksek taze ve kuru ağırlığın% 1 numunelerle (sırasıyla 7.4 ± 0.8mg ve 2.0 ± 0.3mg), en düşük taze ve kuru ağırlığın ise% 3 numunelerle (2.5 ± Sırasıyla 0.2mg ve 1.1 ± 0.1mg) elde edildiğini gösterir. Bitkilerin mutlak büyüme oranı (AGR) ve nispi büyüme oranı (RGR), sırayla değerlendirme sırasına göre elde edilir. Kontrol,% 0.5 ve% 2 numuneler modele yakın doğrusal uyum sağlarken,% 0.5 numuneler uzun kuyruklu pozitif korelasyon uyumu üretir. % 3 numuneler modele negatif bağlanmıştır. CDF modeli % 1 ile yakın ilişki kurar ve kontrol numuneleri oluştururken,% 3 örnekler normal uyuma negatif olarak karşılık gelir. Bu nedenle, mevcut çalışma, karbonu ayırmak ve iklimin azaltılmasında etkin bir şekilde yer almak için bitkilerin biyokütle kazancında yardımcı olacak verimli bir tarım stratejisinin geliştirilmesini önermektedir.
