Chemical composition of pods and seeds of Dichrostachys cinerea as a basis of seed dispersal

1994

The occurrence of very few seeds of Dichrostachys cinerea in the soil seed bank prompted the present study as to why animal browsers and seed predators should select the infructescence of this plant . The preferential and extensive browsing of this indehiscent legume is apparently not due to any exceptional nutritive value of the pods and seeds . However, it is probably the strong rich aroma of the infructescence which initially attracts animals to this food source . The structure of the infructescence, ensures that upon location a large number of pods and seeds are consumed . Ingestion of the pods will provide fibre, lipid, fatty acids, carbohydrates, amino acids, nitrogen and protein . 273 . IntroductionDichrostachys cinerea (L .) Wight et . Am is an indigenous legume invader of grasslands . The seed coat dormancy [10] is broken naturally by alternating temperatures (50/15'C), wet heat, seed burial and ingestion by herbivores [16] . Low numbers of Dichrostachys cinerea seeds were found in the soil seed bank suggesting that the seeds and/or pods are consumed, dispersed or rapidly and heavily predated .A large proportion (95%) of the seeds are lost to bruchid beetle damage . They are also eaten by rodents, black rhino, kudu, nyala, impala, cattle and duiker . Digestion by large mammals is not detrimental as action of gastric juices kills bruchid larvae and allows the seeds to remain viable provided there has not been any damage to the embryonic axis [15] . Seeds egested by large mammals (dispersal agents) have a greater probability of establishment as they end up in a microclimate conducive to germination . Bruchids and rodents are seed predators and destroy the seed .The pods of D . cinerea are indehiscent and collectively up to 40 pods form an infructescence which may attract browsers to the trees . It has not been established to what extent the browsers and seed predators benefit from consumption of pods and seeds of D . cinerea. This study was initiated to establish the nutritional value of the seeds and pods of D . cinerea . . Materials and methods .1 Plant materialMature green infructescences containing mature green seeds were collected from Mkuzi Game Reserve, Zululand . In the green pods, the seeds fill the pods whereas the mature brown seeds found in the brown, dry pods are much smaller . As the pods are indehiscent, animals will always consume both pods and seeds . The reproductive potential of D . cinerea was determined by collecting 30 infructescences and counting the number of pods per infructescence and the number of intact and predated (destroyed) seeds per infructescence . Pods and seeds were separated prior to chemical analysis . All

“…the seed oils of Euphorbia heterophylla L. and E. marginata Pursh have been stated as equal to, or superior to, linseed as a drying oil (Earle et al, 1960). Seeds of Jutropha gossypifoolia L. were reported as a common oilseed crop as compared with palm oil (Husain et al, 1982). The nutkernels of Cnidoscolus margravii contained 28.8% total fat and may serve for the manufacture of paints, soap and other articles where soybean oil is used (Bondar, 1942).…”

The chemical constituents and economic plants of the Euphorbiaceae. A chemical review of the different classes of compounds which have been isolated from the Euphorbiaceae (other than the diterpenoids) is given. This includes triterpenoids and related compounds (sterols, alcohols and hydrocarbons), phenolic compounds (flavonoids, lignans, coumarins, tannins, phenanthrenes, quinones, phenolic acids, etc.), alkaloids, cyanogenic glucosides and glucosinolates. A summary of the industrial and medicinal uses of members of the Euphorbiaceae is provided.
