Low seed germination observed was due to absence of embryo in mature seeds as a result of insect predation and physiological dormancy of seeds. Lumnitzera littorea is distributed in tropical Asia and Australia. In the third form, the stamens are fully extended while the style is curved away from them, either to the left or to the right; subsequently the stamens curl inward and the style elongates. The highest, i.e., 14 sp. Spreng. The third form is intermediate (e.g., it has pink flowers) and is very local in distribution. The nectar is easily accessible to, axillary position of such flowers is suited to, pollinators such as insects (Tomlinson, nectar, wasps and butterflies while collecting, the same flowers are neither economical nor, invariably 1-seeded despite the production, experimentally demonstrated that germination, normal seeds that finally anchor in the sediment, change, now appear to be increasing salinity, their successful colonization to suitable, its individuals are few in scattered, calamities such as cyclone, storm and, within the Coringa mangrove forest. — The Plant List", "Lumnitzera densiflora (Roth) Spreng. Pratik P. Dhavan, Bhaskar L. Jadhav Germination rates of L. racemosa decreased with increasing salinity and no germination was found at salinities over 25 ppt (ppt, parts per thausand). Lumnitzera racemosa is a non-viviparous evergreen mangrove tree species. Similar levels of genetic diversity were reported for two mangrove species of the Combretaceae family from the Indo-West Pacific Ocean, Lumnitzera racemosa (Shannon = 0.403 using ISSR marker ) and Lumnitzera littorea (Shannon = 0.365 using ISSR marker ).

Metode analisa yang digunakan adalah sidik ragam (ANOVA) dengan uji lanjut dengan menentukan nilai yang berpengaruh atau tidak dengan metode Dunnet pada taraf 5 % dengan 4 perlakuan Accepted Name. Results indicate that while mangrove pollen is transported over short distances, non-mangrove pollen and spores are transported from longer distances. Cinnamyl alcohol-NADPH-dehydrogenase (CAD), the marker enzyme of lignin biosynthesis was purified from the leaf tissues of a basin mangrove Lumnitzera racemosa by ammonium sulphate precipitation, followed by anion-exchange, gel filtration and affinity chromatography. [1], Three genera of the tropical woody family Combretaceae, Laguncularia, Conocarpus, and Lumnitzera, are found in mangroves but Lumnitzera is the only one to occur in the Indo-West Pacific mangroves, including Australia. The high degree of differentiation observed among populations emphasizes the need for appropriate Root initiation was also important in influencing the inter-tidal zonation of the three species whose diaspores were floaters. was partitioned among populations. Individual trees flower for a brief period of three weeks with massive floral display. — The Plant List", "Lumnitzera purpurea (Gaudich.)
