摘    要:为研究不同世代组培生姜物质积累与分配特性及其产量形成差异,以确定组培生姜在生产上的最佳推广世代。以组培生姜原原种(T1)、原种(T2)、生产种(T3)3个世代为试验材料,于2017—2018年进行了大田栽培试验。结果表明:T3和T2世代植株生长特性优于T1,表现为生育前期T3和T2株高、茎粗快速增加,地上部快速生长;进入根茎膨大期后,生姜株高和茎粗增长减缓,但分蘖快速发生,由于T3和T2的分蘖发生少,保证了根茎光合产物的供给,延长了快速生长期,显著提高了其物质积累,为高产奠定了物质基础。根茎膨大期后,T3和T2较低的茎、叶和根系物质分配比例,使光合产物向根茎转移促进了根茎的膨大,从而获得高产。因此,与原原种和原种相比,生姜组培生产种具有明显的产量优势,能够有效提高生姜生产的经济效益。综合考虑不同世代组培生姜产量和经济效益差异与...

Abstract:To study the differences in matter production characteristics and yield formation of tissue cultured gingers in different generations, and to determine the best promotion generation of tissue cultured ginger in production, tissue cultured original-original seeds (T1), original seeds (T2) and production seeds (T3) were used as experimental materials to conduct a two-year field experiment in 2017-2018. The results showed that the growth characteristics of T3 and T2 were significantly better than that of T1, which showed the plant height and stem diameter of T3 and T2 grew rapidly, and ensured the rapid growth of shoot in the early growth stage. After entering the rhizome expansion period, the growth of plant height and stem diameter of ginger slowed down, and tillers occurred rapidly. T3 and T2 could effectively control the occurrence of tillering, reduce the consumption of photosynthetic products by excessive tillering, and ensure the supply of photosynthetic products of rhizomes, thereby increased the rate of dry matter accumulation, prolonged the rapid growth period, and significantly increased their dry matter accumulation, laid a material foundation for high yield. After rhizome expansion period, the lower proportion in stem, leaf and root of T3 and T2, which promoted the transfer of photosynthetic products to rhizomes and further promoted the expansion of rhizomes, thus achieved high yield. Therefore, compared with the original-original seeds and original seeds, the production seeds of ginger had obvious yield advantages, which could effectively improve the economic benefits of ginger production. Comprehensive considering the yield differences and economic benefits, and seeds degeneration law of tissue cultured ginger, the tissue cultured ginger production seeds (T3) could be used as the best promotion generation for production, which could realize its yield potential, improve economic benefits and effectively control the occurrence of diseases.
Keywords:ginger  generation  tissue culture  matter accumulation and distribution  yield
