Abstract Fragrant rice is popular for the good grain quality and special aroma. The present study conducted a field experiment to investigate the effects of ultrasonic seed treatment on grain yield, quality characters, physiological properties and aroma biosynthesis of different fragrant rice genotypes. The seeds of three fragrant rice genotypes were exposed to 1 min of ultrasonic vibration and then cultivated in paddy field. The results of present study showed that ultrasonic seed treatment increased grain yield of all fragrant rice genotypes but the responses of yield formation to ultrasonic were varied with different genotypes.

Abstract Brassinolide (BR) is a new green plant growth regulator. The present field study was conducted on two fragrant rice cultivars (i.e., Meixiangzhan-2 and Xiangyaxiangzhan) to study the effects of foliar application of BR on fragrant rice performance. At the heading stage, BR solutions at 0.05, 0.15, 0.25 and 0.50 mg L-1 were sprayed on fragrant rice at 600 liters per hectare; these treatments were named as BR1, BR2, BR3 and BR4, respectively. The treatment sprayed with distilled water was taken as a control (CK). Compared with CK, the BR2 treatment significantly enhanced the chlorophyll concentration and… More >

Abstract Vermicompost is an organic fertilizer contains multiple nutrient elements. However, the application of vermicompost in fragrant rice production is rarely reported. In order to study the effects of vermicompost application on fragrant rice (Oryza sativa L.) seedling performances, present study was conducted with two fragrant rice cultivars and four vermicompost rate treatments (0 (CK), 2.5 (Wo1), 5.0 (Wo2) and 10.0 (Wo3) g kg⁻¹ ). The results showed that vermicompost treatments significantly increased dry weight of fragrant rice seedling by 8.31–32.56% compared with CK. 21.10–59.13% higher net photosynthetic rates and 10.66–59.16% higher chlorophyll contents (chlorophyll a, chlorophyll b More >

Abstract Climate conditions is an important factor affected the fragrant rice growth and development. In order to study the effects of different planting seasons on fragrant rice performance in South China, present study was conducted with three planting seasons (early season (April to July), middle season (June to September) and late season (August to November)) and three fragrant rice cultivars, ‘Basmati-385’, ‘Meixiangzhan-2’ and ‘Xiangyaxiangzhan’. The results showed that the highest grain yield and grain 2-acetyl-1-pyrroline (2-AP, key component of fragrant rice aroma) content were both recorded in late season treatment while the fragrant rice in middle season treatment… More >
