The study was conducted in Completely Randomized Design (CRD) with 5 treatments & four replications. The treatments were T1 (pineapple juice (700ml) + Beetroot extract (35gm)  + 20° brix + Beetroot extract (35gm)  wine yeast (0.133%), T2 (pineapple juice (700ml) + Beetroot extract (35gm)  + 25° brix + wine yeast (0.133%), T3 (pineapple juice (700ml) + Beetroot extract (35gm)  + 30° brix + wine yeast (0.133%), T4 (pineapple juice (700ml) + Beetroot extract (35gm)   + 35° brix + wine yeast (0.133%), T5 (pineapple juice (700ml) + Beetroot extract (35gm)  + 40° brix + wine yeast (0.133%) Total soluble solids, pH and Specific Gravity decreased while the alcohol content, Acidity and the Sensory Qualities increased with increasing length of fermentation. From the above treatments, it is concluded that treatment T4 was found superior in respect of the parameters like Total Soluble Solids, Acidity, pH, Alcohol content, Specific gravity. With respectively Color and Appearance, Taste, Aroma and Overall acceptability also T4 was found best. In terms of economical evaluation, Net return and cost benefit ratio was found best in treatment T4. Since Pineapples contains good sugar proportion which makes it suitable for wine making, while beetroot contains huge amounts of biologically active substances and commonly used in manufacturing as a food coloring agent, the production of wine from this fruit can help increase wine variety and reduce post-harvest losses. This study showed that acceptable wine can be produced from pineapple using yeast especially Saccharomyces cerevisiae.

Plants are subjected to a wide range of environmental stresses which reduces and limits the productivity of agricultural crops. Two types of environmental stresses are encountered to plants which can be categorized as (1) Abiotic stress and (2) Biotic stress. The abiotic stress causes the loss of major crop plants worldwide and includes radiation, salinity, floods, drought, extremes in temperature, heavy metals, etc. On the other hand, attacks by various pathogens such as fungi, bacteria, oomycetes, nematodes and herbivores are included in biotic stresses. Establishment of a reliable, reproducible and efficient in vitro plant regeneration system with cell and tissue culture is a vital prerequisite for biotechnological application of crop improvement programme. An in vitro plant regeneration technique refers to culturing, cell division, cell multiplication, de-differentiation and differentiation of cells, protoplasts, tissues and organs on defined liquid/solid medium under aseptic and controlled environment. Recent progress in the field of plant tissue culture has made this area one of the most dynamic and promising in experimental biology. There are many published reports on in vitro plant regeneration studies including direct organogenesis, indirect organogenesis and somatic embryogenesis. This review summarizes those plant regeneration studies that could be helpful in drawing the attention of the researchers and scientists to work on it to produce healthy, biotic and abiotic stress resistant plant material and to carry out genetic transformation studies for the production of transgenic plants

Abstract. The aim of this research was conducted to improve fruit set using different types of treatments and to find out the best treatment on the basis of number of fruits and pomological traits. For the research, ten years old 12 Lang cultivar of jujube trees and 3 seedlings from open pollinated of Ukraine genotypes were used. The tree spacing was 3.50×1.26 m. Spraying of Borax showed that average numbers of fruits were higher than the other treatments, average values of height, weight, width and thickness were also higher than the other treatments. On the other hand Urea and Girdling gave poor results in both years. In case of seedlings, different treatments for fruit setting have not given good results. Spraying with different treatments did not affect fruit-setting and pomological characteristics as well, in a larger scale. In 2006, bud breaking started in jujube cultivars on 28th April and in seedlings on 6th May. In 2007, bud breaking started in jujube cultivars 11 days earlier and 10 days earlier on 26th April in seedling. In jujube cultivars, there were some variations in the dates of flowering during 2006; the average date of flowering was 26th June in 2006 for all cultivars of jujube. In seedlings, flowering started on 6th July 2006. During 2007 flowering started in jujube cultivar jujube cultivars started flowering 12 days earlier and seedlings 22 days earlier. During 2006, fruit set started in jujube cultivars and seedlings, on 12th July and 14th July respectively. During 2007, fruit set started in jujube cultivars and seedlings on 1st July and 10th July respectively. In 2007 fruit set in jujube cultivars started 11 days earlier and in seedlings 4 days earlier. During 2006, ripening started in jujube cultivars and seedlings on 26th Sept. During 2007 ripening started in jujube cultivars and seedlings on 2nd and 10th Sep. respectively. In 2007, ripening started in jujube cultivars 24 days earlier and seedlings 16 days earlier. Statistical evaluations of the data showed the differences between 2006 and 2007.
