A procedure of shoot tip culture for commercial production of plantlets of Ribes nigrum is described. An average multiplication rate of 4.7 proliferated shoots was achieved within 21 days of shoot tip (1-2 mm) cultures on a Murashige and Skoog (MS) medium supplemented with 1-2 mg 1“1 6-benzylaminopurine and 0.1 mg T1 indole-3-acetic acid. Following 1-3 d of dark treatment with three proliferated shoots per culture tube on half-strength MS medium, 83-96% of these shoots rooted. When these rooted shoots were transferred to wooden boxes with vermiculite as supporting medium for hardening, 97% survived. Plantlets grew well after transplanting to the nursery field. It is concluded that the use of (i) smaller shoot tip explants during shoot profileration stage, (ii) initial three days of dark treatment during the root initiation stage, and (iii) vermiculite as a supporting medium for plantlets during the hardening stage, are economic, efficient and practical procedures for commercial production of plantlets of R. nigrum by shoot tip cultures. 相似文献

对国家果树种质资源郑州葡萄圃内的94 份无核葡萄和40 份巨峰系葡萄的果粒颜色、形状、质量和大小进行了连续3 年的调查和统计分析。结果表明, 无核葡萄种质果粒质量和果粒大小遗传变异系数比巨峰系大得多, 无核葡萄种质的平均果粒质量主要在110~510 g 的范围内, 将近50 %无核葡萄种质的果粒为115~215 g , 为中等。因此目前国际及国内的现有描述评价标准都不适合评价无核葡萄种质的果粒质量及大小。根据本项研究结果提出了适合无核葡萄种质新的附加分级评价标准。 相似文献
