Evidence of castor plant R. communis, L. is recovered from the Early Holocene archaeological site of Kabbashi Haitah in the Central Sudan and dated to c. 7700 - 7200 bp. This evidence represents the earliest botanical evidence recovered –so far- from the Central Sudan and elsewhere in Eastern Tropical Africa and the World. No evidence is found in the material culture remains which might indicate the likelihood of its being imported. Most of the ancient and traditional utilizations of castor plant are strikingly similar despite their being practised at different times in different and far apart regions in the World. This modest contribution stands to show that the wide spread and utilizations of castor plant strongly accentuate its significant and indispensable role since ancient times. It also reflects that inedible plants, as seen in the case of castor plant, were (and still are) not less important than food plant, hence stresses the need for attending to their study in a fashion equal to that of studying foodplants since prehistoric and early historic times.

Effect of supplemental Ca2+on NaCl-stressed castor plants (Ricinus communisL.)Greenhouse experiments were conducted to assess the effects of supplemental Ca2+in salinised soil on germination and plant growth response of castor plant (Ricinus communisL. Var. Avani-31, Euphorbiaceae). NaCl amounting to 390 g was thoroughly mixed with soil of seven lots, of 100 kg each, to give electrical conductivity of 4.1 dS m-1. Further, Ca(NO3)2x 4H20 to the quantity of 97.5, 195, 292.5, 390, 487.5, and 585 g was separately mixed with soil of six lots to give 1:0.25, 1:0.50, 1:0.75, 1:1, 1:1.25, and 1:1.50 Na+/Ca2+ratios, respectively. The soil of the seventh lot contained only NaCl and its Na+/Ca2+ratio was 1:0. Soil without addition of NaCl and Ca (NO3)2x 4H20 served as control, with a 0:0 Na+/Ca2+ratio. Salinity significantly retarded seed germination and plant growth, but the deleterious effects of NaCl on seed germination were ameliorated and plant growth was restored with Ca2+supply at the critical level (1:0.25 Na+/Ca2+ratio) to salinised soil. Supply of Ca2+above the critical level further retarded seed germination and plant growth due to the increased soil salinity. Salt stress reduced N, P, K+and Ca2+content in plant tissues, but these nutrients were restored by addition of Ca2+at the critical level to saline soil. In contrast, Na+content in plant tissues significantly increased in response to salinity, but significantly decreased with increasing Ca2+supply to saline soil. The results are discussed in terms of the beneficial effects of Ca2+supply on the plant growth ofRicinus communisgrown under saline conditions.

And Storage

Two new anthocyanins (1, 2) were isolated from the stem bark of the castor plant, Ricinus communis L. by a combination of chromatographic techniques. The structures of the compounds were elucidated, mainly by nuclear magnetic resonance spectroscopy and high-resolution electrospray mass spectrometry, to be cyanidin 3- O-β-xylopyranoside-5- O-β-glucopyranoside (1) (21%), and cyanidin 3- O-β-xylopyranoside-5- O-(6′”- O-malonyl-β-glucopyranoside) (2) (79%). In addition, cyanidin 3- O-β-xylopyranoside-5- O-(6′”- O-methylmalonate-β-glucopyranoside) (3), formed by methyl esterification of the malonyl unit of 2 during isolation and storage, was identified.

The World

Castor (Ricinus communis L.) is a plant that is commercially very important to the world. It is produced in about 30 countries lying in the tropical belt of the world. It is an important plant for production of industrial oil. Assessment of genetic diversity of a crop species is a prerequisite to its improvement; hence it is important to identify the genetic diversity of castor genetic resources for development of improved cultivars. The present study is focused on estimation of genetic distance between 56 Tunisian castor genotypes, based on 18 RAPD markers. Seeds of castor were obtained from the University of Carthage, National Institute of Research in Rural Engineering, Waters and Forests (INRGREF), Regional Station of Gabès, Tunisia. The ricin genotypes were obtained from 12 regions of Tunisia. The efficacy of the RAPD technique in this study is further supported by the obtained PIC values of the primers used in the analysis. PCR amplification of DNA using 18 primers for RAPD analysis produced 145 DNA fragments that could be scored in all 56 genotypes of Tunisian castor. The number of amplified fragments varied from 3 (OPE-07) to 13 (SIGMA-D-01), and the amplicon size ranged from 100 to 1500 bp. Of the 145 amplified bands, 145 were polymorphic, with an average of 8.11 polymorphic bands per primer. The lowest values of polymorphic information content were recorded for RLZ 9 (0.618) and the the highest PIC values were detected for OPD-08 (0.846) with an average of 0.761. A dendrogram was constructed from a genetic distance matrix based on profiles of the 18 RAPD primers using the unweighted pair-group method with the arithmetic average (UPGMA). According to analysis, the collection of 56 Tunisian castor genotypes were clustered into five main clusters. Genetically the closest were four genotypes from cluster 1 (BT-1 – S-5 and K-1 – N-3). Knowledge of the genetic diversity of castor can be used in future breeding programs for increased oil production to meet the ever increasing demand of castor oil for industrial uses as well as for biodiesel production.
