摘　　要：以新香优80、R80、TANGARA和IAPAR9为材料,进行水旱种比较试验,并以TANGARA为材料,喷洒多效唑、云大120、黄腐酸3种植物生长调节剂,对不同时期的陆稻进行化学调控,初步研究水、旱种及化学调控对稻米营养品质的影响。结果表明：各品种水种的米质优于旱种,以IAPAR9品质最优,R80其次;旱种下,TANGARA品质最优,R80其次。喷洒化学药剂能有效地改善稻米的营养品质,提高粗蛋白质含量,与对照相比,黄腐酸处理的粗蛋白质含量增加10.7%,多效唑处理增加7.5%,云大120处理增加5.5%。3种植物生长调节剂有利于提高水稻整精米率,降低垩白率。Arenaria rotumdifolia Bieberstein has a strong ability to absorb heavy metal Pb. In order to solve the problem of seeding supply for phytoremediation of Pb polluting soil in mining area, tissue culture conditions of Arenaria rotumdifolia Bieberstein were studied by using apical buds or stems of Arenaria rotumdifolia Bieberstein as explant materials. The results showed that the suitable medium for callus induction of A renaria rotumdifolia Bieberstein was MS＋ 6-BA 0.2 mg/L ＋ NAA 0.02 mg/L, the best mediums for bud differentiation was MS＋6-BA 1 mg/L＋NAA 0.1 mg/L, and the best mediums for root formation was MS＋6-BA0.1 mg/L＋NAA 0.5 mg/L. But pollution in the process of tissue culture and low survival rate after temporary planting should be studied in further.
