Studies on the Physiological and Biochemical Composition of Different ber (<i>Zizyphus mauritiana</i> Lamk.) Cultivars at Rajshahi

Abstract

An investigation was carried out at the Bangladesh Council of Scientific and Industrial Research (BCSIR) Laboratories. Binodpur Bazar, Rajshahi during the period November 2006 to March 2007 to evaluate the physiological and biochemical composition of five cultivars of ber (jujube). Among the fruit cultivars, Thai kul produced the largest fruits (51.85 g each) having the highest pulp (92.38%) and juice (60%) and also the lowest vitamin C content (21.13 mg/100g). The fruit weight of the other cultivars varied from 9.6 0 to 45.09g. The seed weight ranged from 6.38 to 15.00%. Sugar content varied from 6.25% to 9.72% and starch content ranged from 0.715% to 0.963%. The apple kul had the highest qualitative score through organoleptic test while Thai kul had the lowest. The highest edible portion (pulp content) was in Narikeli kul (93.61%) and that of lowest in Apple kul (85.38%) and Local kul (85.38%) respectively. Considering all, fruit characters and yield are potential. Keywords: Ber, Cultivar, Fruit characters, Quality, Yield. DOI: 10.3329/bjsir.v44i2.3678 Bangladesh J. Sci. Ind. Res. 44(2), 229-232, 2009

Potential Antioxidant and Antibacterial Properties of a Popular Jujube Fruit: Apple Kul (Zizyphus mauritiana)

“…It is fleshy and juicy and has a smooth skin and a sweet taste. Its whole weight is approximately 9.6 g and it contains 85.94% pulp, 14.06% stone and 40.00% juice of its whole weight (Ibrahim et al 2009). Apple kul has a high yielding capacity and is suitable for cultivation.…”

Phytochemical Constituents and Antioxidant Activities of Some Indian Jujube (Ziziphus mauritiana Lamk.) Cultivars

“…Thus, it is important to characterize different types of fruits for the content of such substances in order to better identify their overall nutritional value (Kamiloglu et al 2009), which in turn may depend on the specific plant genotype. Elsewhere, the health-promoting components of a few Indian jujube genotypes have been reported (Muchuweti et al 2005;Ibrahim et al 2009;Memon et al 2012). However, more detailed information about the health-promoting components of different ber genotypes, grown in India, could lead to a better understanding and appreciation of the pharmaceutical, nutraceutical and medicinal value this fruit offers, and an increased consumption of the fruit by the general public.…”

Evaluation and Economic Analysis of Some Integrated Pest Management Packages for Suppressing Tube Spittle bug (<i>Machaerota planitiae</i> Distant) Infesting Jujube (<i>Zizyphus mauritiana</i> Lamk), in North-Western Bangladesh

“…The jujube (Zizyphus mauritiana Lamk), tropical fruit species belonging to the family Rhamnaceae is locally known as 'kul' or 'boroi'. Ber is a popular fruit in Bangladesh (Ibrahim et al, 2009). It is gaining popularity among the growers because of its higher yield, higher economic return and suitable for the arid and semi-arid regions of Bangladesh where most of other fruit crops cannot be grown either due to lack of proper irrigation facilities or adverse climatic and soil conditions (Bose and Mitra, 1990).…”
