“…The cashew apple is an accessory fruit (sometimes called a pseudo or false fruit), a hypocarpium, that develops from the pedicel and the receptacle of the cashew flower (Varghese and Pundir, 1964). The cashew apple has a base at the point of attachment to the peduncle, ridges on its body and a cavity attached to the nut.…”

To promote the better utilization of genetic resources of cashew, 91 accessions maintained at Cashew Research Station, Madakkathara were assessed for 38 phenotypic traits. Frequencies of the phenotypic classes of each character were calculated. The Shannon diversity index (H ') was used to estimate the magnitude of diversity. Polymorphism was high for tree habit (0.96), tree height (0.89), branching pattern (0.89), colour (0.80), ridges (0.93), apex (0.95), cavity (0.90) and weight (0.84) of cashew apple, attachment of nut to apple (0.85), flanks of nut (0.95) and cotyledonary grooves (0.99). The cluster analysis using the squared Euclidean distance method classified the accessions into 13 clusters at a 55 per cent similarity level. More than 50 per cent of the accessions were high yielding with moderate quality kernels. Grouping of the genotypes into agronomic groups revealed the existence of highly prolific accessions with high quality kernels that can be exploited for crop improvement programmes.

“…Schizogenous development of ducts is reported for some members of Anacardiaceae as in Rhus diversiloba (McNair 1918), Schinus (Venning 1948), Rhus glabra (Fahn & Evert 1974) and Anacardium occidentale (Nair et al 1983). Lysigenous development of ducts is reported in floral organs of Mangifera indica (Venning 1948), pseudocarp of Anacardium occidentale (Varghese & Pundir 1964), shoot and fruit of Mangifera indica (Fahn & Joe11976; Joel & Fahn 1980a, b, c), shoot of Schinus molle (JoeI1978) and root of Pistacia lentisus (Joel 1978).…”

Development and ultrastructure of primary phloem secretory ducts in the stem of Semecarpus anacardium are described. Ducts are formed schizolysigenously in the phloic procambium of the young stem just below the shoot apex. The cytoplasm of the epithelial cells is rich in osmiophilic material (resin), plastids, rough endoplasmic reticulum (RER), free ribosomes, polysomes, mitochondria with swollen cristae and golgi bodies. The plastids are of varying shapes, have an electron dense matrix and a poorly developed internal membrane system. They are highly contorted and invariably surrounded by a sheath of RER. Osmiophilic material is frequently observed in the plastid stroma. Epithelial cell cytoplasm and its plastids are the plausible sites of resin formation. The gum component of the secretion may be derived from the inner tangential wall (ITW). The secretory substances reach the apoplast principally by granulocrine and eccrine secretion. Epithelial cells are linked with each other and with the neighbouring cells by numerous plasmodesmatal connections. Some epithelial cells undergo lysis while others retain their secretory function.

“…Other studies of Anacardium (Nair et al 1983), Toxicodendron (McNair 1918, and Schinus (Venning 1948) reported their development as being schizogenous. However, Anacardium hypocarp secretory ducts were reported to be lysigenous (Varghese and Pundir 1964), as were vegetative and reproductive organs of Mangifera (Venning 1948;Fahn and Joel 1976), and shoots of Schinus (Joel 1978).…”

Neotropical Anacardiaceae (cashew family)

et al. 2022

View full text Add to dashboard Cite

Anacardiaceae is an ecologically and economically important plant family of about 200 species in 32 genera in the Neotropics. The family is particularly diverse in leaf architecture and fruit morphology, making it a model family to study the evolution of structural diversity as it correlates with lineage diversification. This fruit diversity is the primary reason 11 of the Neotropical genera are monotypic and that so many genera are recognized in the Anacardiaceae. The economic value of the family is driven by the global markets for cashews, mangoes, and pistachios, but there is great potential value in its medicinal properties. At least 10 Neotropical genera cause contact dermatitis, which is a rich area for research in the family. Here presented is a review of the systematics and structural diversity of the family. Particular attention is given to the morphology, economic botany, paleobotany, ecology, and taxonomy of native and naturalized genera. Keys to Neotropical Anacardiaceae subfamilies and genera are provided along with descriptions of native genera.
