A significant difference was noted in the non-synchronously-emerged tillers （the tillers that formed from latent buds and did not emerge following the normal tillering law on seedling nursery beds and recovered to grow after scattered-planting or transplanting） as well as the percentage of the available synchronously-emerged tillers between seedlings raised on plastic trays under dry-land conditions （DPT） and seedlings raised on nursery beds under wetland conditions （WB）. The seedlings under DPT had some non-synchronously-emerged tillers, but those under WB had not. Therefore, the traditional formula for determining the number of rice seedlings was improved, and the formula for determining the number of basic seedlings under scattered planting with DPT in double-season rice was introduced. For early rice, it was X=Y/{（I＋t1r1）[1＋（N-n-SN）Rr2]＋（SN-3-t1）R2r5}, and for late rice, it was X=Y/{（1＋t1r1）[1＋（N-n-SN）Rr2]＋（N-n-SN-3）Rr2R1r3＋（SN-3-t1）R2r5}. Where, X represents reasonable number of basic seedlings per unit area at scattered-planting; Y, number of fitting panicles per unit area; t1, total number of tillers per plant; r1, percentage of the total available tillers; N, total number of leaves of the main culm; n, total number of elongated internodes in the main culm; SN, seedling leaf ages at scattered-planting; R, percentage of the primary tillers emerged in available node-position; r2, percentage of the available primary tillers; R1, percentage of the secondary tillers in the field （except the secondary tillers of the seedlings）; r3, percentage of the available secondary tillers; R2, percentage of the asynchronously-emerged tillers after scattered-planting; r5, percentage of the available non-synchronously-emerged tillers after scattered-planting.展开更多

Seven days later, all transplanted tumor were formed and the mice were intraperitoneally injected 200 mg/kg cytoxan(CTX) to establish the models of tumor-bearing mouse chemotherapy, then they were randomly divided into model group, continuing CTX chemotherapy group(CTX group), and three CHBF(117, 58.5 and 29.25 g/kg) groups. After ten days of treatments, histology was observed, contents of VEGF, KDR and b FGF in serum and tumor tissue were measured by enzyme-linked immunosorbent assay(ELISA), VEGF and b FGF protein expression and MVD tagged by CD34 were detected by immunohistochemisty.RESULTS: MVD in CHBF(117, 58.5 g/kg) and CTX groups was significantly lower than that in model group(P < 0.01); expressions of VEGF, KDR and b FGF in serum and tumor tissue in CHBF(117 g/kg)group were less than those in model group(P <0.05; P < 0.01); the expressions of MVD, VEGF and b FGF in tumor tissue of CHBF(117 g/kg) groupwere also less than those in CTX group(P < 0.05;P < 0.01).CONCLUSION: CHBF can effectively reduce the expression of VEGF, KDR and b FGF in serum and tumor tissue, and decrease MVD and delay tumor progression.展开更多
