“…The emergence of more than one seedling from a single seed due to polyembryony has already been reported in jamun [38]. However, this is the first report where a significant effect of the propagation substrate was found on emergence of multiple seedlings from a single seed (table II).…”

Introduction. Jamun, propagated through seed for raising rootstock, involves a lot of cost and risk for maintenance until attainment of graftable size. Use of suitable growing substrates is essential for production of quality nursery plants. Chemical mutagenesis is a simple approach to create mutation in plants for improvement of potential agronomic traits in rootstock materials. Materials and methods. Seeds originating from a single 'elite' tree were soaked in 0.1 and 0.5% ethyl methane sulfonate and colchicine solutions for 24 h prior to sowing in different propagation substrates (Arka fermented coco-peat and a mixture of sand, soil and farmyard manure). Morphological, physiological and biochemical analyses were performed after 3 months. Results and discussion. The Arka fermented coco-peat substrate resulted in earlier and higher seed germination, higher polyembryony, greater accumulation of photosynthetic pigments and total carbohydrates, and lower synthesis of stress-induced metabolites in leaves. These performances were probably due to a better balance between the water and air capacity than in the other growth substrate. Among different doses of chemicals, colchicine at 0.1% concentration was found to stimulate early seedling emergence, improve plant morphological characters and enhance production of total chlorophyll and total carbohydrates in leaves. Conclusion. The graftable stage can be attained rapidly if jamun seeds are treated with 0.1% colchicine and sown in Arka fermented coco-peat substrate.

Skeels) sur différents substrats. Introduction. Le jamelonier est traditionnellement multiplié sur porte-greffes issus de semis, ce qui engage des coûts élevés et des risques liés à l'entretien des porte-greffes jusqu'à la taille convenable au greffage. L'utilisation de milieux de culture appropriés est essentielle à la production de plants de pépinière de bonne qualité. La mutagenèse chimique est une approche simple pour créer une mutation sur les plantes porte-greffes pour en améliorer les caractéristiques agronomiques potentielles. Matériel et méthodes. Les graines originaires d'un seul arbre « élite » ont été trempées dans une solution de sulfonate de méthane d'éthyl ou de colchicine à 0,1 ou 0,5 % pendant 24 h avant semis sur un substrat composé d'un mélange coco-tourbe fermenté (Arka) ou d'un mélange de sable, terre et fumier de ferme (SS). Des analyses morphologiques, physiologiques et biochimiques ont été réalisées sur les plantes après 3 mois. Résultats et discussion. Le substrat Arka a permis une germination des graines plus précoce, une polyembryonie plus forte, davantage d'accumulation de pigments photosynthétiques et de glucides totaux que le substrat SS, et une synthèse plus faible de métabolites induits par le stress mutagène dans les feuil...

“…The skin of the fruit is glossy and smooth with purple or white pulp, discolored bark, rough and cracked on the lower part of the trunk (Bijauliya et al, 2017). Fresh seeds contain 20-80% of the total fruit weight with 6% seed coat and 94% cotyledons (Sivasubramaniam and Selvarani, 2012). Depending on the fruit size there are two varieties of Syzygium cumini; small and big, the smaller variety is round and has sweet flesh with low content of acids, tannins and anthocyanins.…”

Syzygium cumini (S. cumini) is an underutilized fruit of tropical and subtropical regions with various bioactive compounds distributed in all parts of the plant. The fruit and its by-products, such as seeds, have both nutritional and medicinal value. However, fruit and seeds have not been fully considered as potential functional food ingredients to develop foods with promising health benefits. Based on the available information in the literature, fruit and seed are rich in phytochemicals, such as myricetin, oxalic acid, gallic acid, citronellol, cyanidin diglucoside, hotrienol, phytosterols, flavonoids, carotenoids and polyphenols as well as micronutrients. In addition, they were reported to possess several beneficial health properties. Further, research in this area would provide valuable information for their potential utilization as functional food ingredients. This review presents comprehensive information about the bioactive compounds and nutraceutical properties of S. cumini fruit and seeds, as well as the potential of using them as functional food ingredients

“…Such embryos are often asexual. The seeds may be polyembryonic but all the embryos do not germinate (Sivasubramaniam and Selvarani, 2012). Rate of polyembryony was also observed to be varying from seed to seed, fruit to fruit, sector to sector and from year to year in the same plant (Soares Filho et al, 1995).…”
