Organoleptic and grain quality traits of aromatic rice varieties as influenced by supplementation of Zn and 2-acetyl-1-pyrroline

Abstract

Aromatic rice fetches premium prices in world markets due to its pleasant smell and enchanting flavor. In Bangladesh, the quality of aromatic rice is much inferior than those of other rice growing countries because of lack of improved variety and judicious agronomic management. Selection of appropriate variety and supplementation zinc (Zn) and 2-acetyl-1-pyrroline (2-AP) can improve the aroma. The present study exhibited the effects of 2-AP and Zn supplementation on yield and quality of aromatic rice. Two well-known aromatic cultivars, BRRI dhan80 and BRRI dhan34, were cultured separately in pot supplemented with 2-AP and Zn. The results showed that supplementation of 2-AP and /or Zn along with conventional practices had significant effects on organoleptic and some quality parameters studied in this study. The concentration of 2AP and Zn in rice grain increased with increasing their application rate. Additionally, grain 2-AP concentrations were significantly and positively correlated with organoleptic characters. Interactions of both these elements with the complex process of 2-AP formation remain to be explored.

Response of Rice (Oryza sativa L.) to Soil and Foliar Application of Nano-ZnO and Bulk Zn-fertilizer in Red Acidic Soil of West Bengal, India

“…Kandoliya et al (2018) reported that soil Zn application influenced wheat grain protein content.Foliar Zn spray was found to be the most effective way to increase grain protein content (Kamboj & Mathpal, 2019). Roy et al (2019) reported a positive linear relation (R² = 0.0774) between grain Zn content (g) and grain protein content (µg/g).…”
