Rhee, Y.; Sekhon, R.S. ; Somchit, M.N. Similar to the Makapuno, the Lono nut could only be distinguished from other nuts upon splitting of the nut. The coconut is a major crop of many tropical countries, with the endosperm being one of its main products. In angiosperms, the zygote is diploid, while the primary endosperm cell is triploid.

Hence, a coconut has many uses and applications throughout its various stages of development, which is why it is present in daily diets all over the world, in one form or another. As a coconut continues to ripen, layers of endosperm deposit on the insides of the walls of the coconut, making up the edible ‘flesh’ of coconuts. ; Rival, A.

By the third month of fruit development, there are small quantities of coconut water. Some important coconut genes deposited in the NCBI nucleotide database so far are those for fatty acid biosynthesis and oil storage, carbohydrate metabolism, plant defense, hormone synthesis, and for plant development.

This is what forms the characteristic coconut meat. The xenia effect has been found in dates, maize and coconuts [, The Makapuno nut is classified into three types based on the appearance of the solid and liquid endosperms, with type A having the same thickness as the normal and its liquid endosperm being slightly viscous, type B with a thicker solid endosperm having a soft inner layer and a very viscous, translucent liquid endosperm, and type C having the thickest solid endosperm and a soft inner proliferating layer filling up the whole cavity while its liquid endosperm is almost non-existent and is replaced by an oily semi-solid endosperm [, Depending on the study, proteins, fats, and sugars levels were similar or different between Makapuno and the normal coconut endosperm [, The characteristic viscous and jelly-like Makapuno endosperm is generally attributed to the increased galactomannan content compared to the normal coconut and depends on the developmental stage [, Two forms of AGAL were also observed by Mujer et al., (1984) [, Recently, Dela Cruz et al., (2013) reported the cloning of partial cDNAs from normal and Makapuno coconut solid endosperms [, The Lono cultivar is a high-value, soft-endosperm coconut [, Lono trees are about 6–6.5 m tall and measures 91 cm in its stem while its trunk’s diameter is 1 m from the base of the plant. 35–40. ; Sarpan, N.; Azimi, N.; Hashim, A.T.; Ishak, Z.; Rosli, S.K. ; Li, Q.; Rohr, N.A.
