Until 1960 all the chromosome counts performed on cells of this species were done on histologically prepared specimens of testicular tissue. In January 1960, Chiarelli et al. published the results of their experiments to grow renal tissue in culture. Their specimens were obtained from male and female calves. They confirmed that 2n = 60 and described the chromosomes as being all acrocentric except the X chromosome, which was submetacentric.The purpose of the work described below was to try to apply the peripheral-blood culture technique of Moorhead to bovine blood, and to attempt to grow bovine muscle cells in a tissue culture.

Pineapple propagation by lateral shoots, suckers or crowns is often confronted with limited number of regenerated seedlings and high diversity in flowering and fruit formation. In order to solve this problem, this study offer an alternative method by using tissue culture techniques. This study aimed to determine the effect of growth regulators on plantlet regeneration from bud slicing of pineapple cv. Tangkit. Four levels of 2.4-D (0.0, 0.001, 0.01 and 0.1 ppm) in combination with BA (0.0, 0.1, 1.0 and 10.0 ppm) were tested on solid MS medium. Cultures were incubated in total darkness for a week followed by transfer to 16-hour photoperiod. Results showed that explants treated with 2,4-D and/or BA succeeded in regenerating adventitious shoots. Average leaf number did not differ significantly among treatments (P = 0.60). Highest leaf number (2.99 ± 0.23) was obtained on medium with 0.01 ppm 2,4-D without BA, followed by 0.1 ppm 2,4-D without BA (2.85 ± 0.33). Meanwhile, roots were only formed on medium with 0.1 ppm 2.4-D without BA (4.2 ± 0.37 per shoot). Thus, complete plantlets were regenerated only on medium supplemented with 0.1 ppm 2,4-D without BA. The growth of plantlets was relatively uniform, and plantlet acclimatization succeeded 100% on Jiffy pots. The finding of optimum concentration of 2.4-D and BA in this study is important to develop standard protocol for in vitro propagation of pineapple cv. Tangkit. Thus, the benefit of producing seeds in large quantities and relatively uniform in growth is made possible through tissue culture technique.

Tissue Culture Techniques

During the last three decades, plant cell, tissue, and organ culture have developed rapidly and become a major biotechnology tool in agriculture, horticulture, forestry, and industry. Many problems in conventional breeding techniques were solved via tissue culture techniques. Plant tissue culture technique permits the growing plants in test tube or closed container in vitro under controlled environment. This technique is devoted to solve two problems: 1) To keep the plant cells free from microbes. 2) To grow the desired plants by providing suitable nutrient medium and other environmental conditions. In this chapter, a review around plant tissue culture techniques that have been reported on oil palm breeding programme will be discussed. It is including the laboratory techniques, advantages and disadvantages of the technique, the problems to produce good and prolific oil palm tissue culture clones and mitigation measures that have been reported to overcome the problems. As a conclusion, this chapter reviews tissue culture techniques that could be used to propagate oil palm clones.

Neolamarckia cadamba (kelempayan) is a multipurpose and fast growing timber species. The tree is grown for timber, paper-making and as ornamental plant. It is reported that its barks and leaves possesed medicinal values and its flowers are used in perfumes. The species is also known to be suitable for plywood, packing case, toys and short-fibred pulp. Therefore, mass production of high quality planting material of N. cadamba is important to support plantation program of this species. Here we presented mass production of N. cadamba through tissue culture techniques. Nodal segments derived from in vitro germinated seeds were used and induced direct organogenesis to produce shoots and roots using MS media (1962) and plant growth regulators (BAP and IBA) that are relatively cheaper than previously used methods. The tissue culture technique of N. cadamba developed may help in ensuring supply of planting materials that are feasible for commercial plantation purposes.

Abstract Tissue culture techniques can increase the number of garlic seedlings. The purpose of this research is to determine the effect of NAA and coconut water in increasing the number of garlic seeds. This research used a Completely Randomized Design of two factors. The treatment used is NAA with concentrations of 0 ppm, 0.5 ppm, 1 ppm, 1.5 ppm, and coconut water concentrations of 0%, 10%, 20%. The variables observed were shoot emergence time, root emergence time, number of shoots, number of roots, number of leaves, shoot height, root length, and number of plantlets. The results showed that the addition of coconut water 20% without the addition of NAA in 1 bulb can produce 3.33 planlets and the results of explant propagation in 1 bulb can produce the number of shoots as many as 15.33 shoots. Giving coconut water with concentrations of 10% and 20% can increase the number of leaves, shoot height, and some planlets. The concentration of NAA 0.5 ppm can accelerate the root emergence time on garlic explant.
