“…Ayala-Silva et al, [11], reported that mechanical scarification is an effective method of increasing seed coat permeability in Tamarindus indica seeds. Rusdy et al, [12] investigated how mechanical scarification affected the germination of Leucaena leucocephala seeds and concluded that scarifying seeds by clipping the seed coat around the micropyle at the distal end considerably improved germination.…”

Acacia nilotica plays an important ecological role in its native habitats and has great relevance for restoration as well as in terms of economic worth. Acacia nilotica species frequently exhibit seed dormancy, which makes planting and seed testing difficult. In the present work, we examined the degree of dormancy and the impact of various pre-treatments on the dormancy breaking of Acacia species. Several tests were carried out against this backdrop to standardize the mechanical scarification, seed priming, and coating techniques. The results showed that mechanical scarification of Acacia nilotica seeds with @6 min scarification improved the seed germination percentage and vigour index percentage by 117 and 184 percent over the control. Correspondingly, the application of the TNAU seed coating formulation on Acacia nilotica seeds at 2g kg-1 increased the germination percentage and vigour index percentage by 129 and 186 percent, respectively, over the control. Also, humid priming of Acacia seeds (12 h soaking in water + 2 days humid incubation) resulted in a gradual increase in the seed germination percentage and vigour index percentage by 181 and 263 percent over the control. The seeds were not harmed by any of these treatments, which all reduced hard seeds to zero and improved germination percentages.

“…Tamarindus indica L. (tamarind) is a widely distributed tropical fruit tree found in Africa and Asia (Morton, 1987;El-Siddig et al, 1999;Janick and Paull, 2008;Ayala-Silva et al, 2010. Although its precise origin is unknown, most systematists consider tamarind to be indigenous to the drier grasslands of tropical Africa (Gunasena and Hughes, 2000;Ayala-Silva et al, 2013). However, it has long been naturalized in tropical Asia, the Caribbean, Mexico and Central America.…”

“…Tamarind, which originated in India, is the only genus belonging to the family Fabaceae (Leguminosae), and it is popularly known as 'Indian Date' (Morton, 1987). It is primarily valued for its fruits, especially the pulp, which is used for a wide variety of domestic and industrial purposes (Morton, 1987;Parrota, 1990;Janick and Paull, 2008;Ayala-Silva et al, 2013).…”

“…Ripe tamarind fruit is popular, due to its acidic sweetness: it is used in desserts, such as jam, blended into juices or sweetened drinks or eaten as a snack; tamarind is also a natural laxative (Morton, 1987;Okello, 2010;Ayala-Silva et al, 2010). The pulp is also a rich source of carbohydrates and vitamins (Karnataka, 2004;Okello, 2010;Obulesu and Bhattacharya, 2011;Ayala-Silva et al, 2013;Gullipalli and Kasiviswanatham, 2013) and is widely used as a spice in the preparation of chutneys, sauces, soups, and certain beverages. Because it is very rich in ascorbic and tartaric acids, tamarind is also used as a food preservative (El-Siddig et al, 2006;Gullipalli and Kasiviswanatham, 2013).…”

“…Farmers have generally selected genotypes from natural populations based on desirable fruit characteristics, such as fruit pulp quality. Variation in the vegetative growth characters, such as shoot length, root length, germination percentage, plant height, and pinnae per plant have been recorded for many cultivated genotypes (Bennet et al, 1997;Ayala-Silva et al, 2013).…”

Tamarind (Tamarindus indica L.) is a large evergreen tree belonging to the family Fabaceae (Leguminosae). Its fruits are eaten fresh, processed into a paste, used as a spice, made into a beverage, and used for tanning hides. Although this commercially important species has a wide geographical distribution, research on tamarind is sparse. Hence, the purpose of our research was to characterize 13 genotypes of tamarind at the Subtropical Horticultural Research Station in Miami, FL, USA, and to determine whether physical and pomological traits of this collection in fact reflect the genetic diversity within this fruit tree species. This work was conducted at SHRS in Miami, Florida. The pomological diversity of 13 tamarind genotypes was analyzed based on 18 qualitative and quantitative traits. Principal components analysis (PCA) conducted on quantitative traits showed an important degree of variability of about 72% for the first three principal components. A dendrogram was constructed based on average distances. Cluster analysis grouped all tamarind genotypes into three major clusters ('A', 'B' and 'C'). Cluster 'B' includes the genotypes predominantly with brown to dark brown sweet and semi-sweet pulp and from South East Asia (Thailand and Philippines); the B cluster individuals were then grouped into sub-clusters 'B1', 'B2', 'B3' and 'B4'. Semi-sour genotypes were grouped in cluster 'A' and the sour genotype in cluster 'C' Cluster 'B' contained genotypes predominantly characterized by sweet, dark pulp, and smaller fruit size, while the sour genotypes were characterized by trees of sour pulp and from other regions (Australia, Brazil, India and the Caribbean). We detected moderate genetic diversity among these tamarind genotypes. This information could be used as a basis for selection during genetic improvement of tamarind genotypes.
