Seed morphology (seed length and 20 seed weight) and oil content was studied in Azadirachta indica A. Juss. (Neem) of five provenances of northern and western India. Trees with wide ranges of girths were considered for study. Maximum average oil content was observed in trees from Hisar provenance. Seed oil content in most of the provenances was not consistently and significantly correlated with morphological parameters of seeds. Age of the tree had no significant effect on the oil yield.  相似文献

Buffalo (Bos bubalis) lymphocytes were purified and tested for their E and EAC rosette forming capacity as a marker for the detection of T and B cells, respectively. Sheep erythrocytes were found to form 17.7 per cent of E rosette with buffalo lymphocytes. This population of lymphocytes is believed to be T cell. Erythrocytes of guinea-pig, rabbit, hamster, rat, chicken, dog and donkey formed a lower percentage of rosettes. Five to 18.5 per cent of SRBC-EAC rosettes were detected with buffalo lymphocytes which are believed to be B cells.  相似文献

Distribution of T- and B-lymphoid cells in peripheral blood, lymph node, spleen and bone marrow of normal healthy calves and calves immunized against Theileria annulata followed by challenge on Day 50 post-immunization were studied by rosette tests. Significantly increased percentages of T- and B-lymphoid cells were recorded in immunized calves.  相似文献
