尽管水稻对硼(B)缺乏相对不敏感(Rerkasem等人1988年，Rerkasem和Jamod 1997年)，但在巴基斯坦(Chaudhary等人1977)和其他地方(Shorrocks 1997)都患有这种疾病。例如，巴基斯坦约有60万公顷大米患有缺硼(NFDC，1998)。虽然B肥是解决这一问题的最简单和最具成本效益的方法，但各种实际限制因素阻碍了种植低B土的农民采用B肥。在许多作物品种中，获得硼的遗传变异和生物量生产的效率被用来控制缺硼(Rerkasem和Jamod 1997)。因此，我们研究了巴基斯坦几个主要水稻品种的比较硼效率。
Rice, despite being relatively insensitive to boron (B) deficiency (Rerkasem et al 1988, Rerkasem and Jamod 1997), suffers from this disorder in Pakistan (Chaudhary et al 1977) and elsewhere (Shorrocks 1997). For example, about 0.6 million ha of rice in Pakistan suffer from B deficiency (NFDC 1998). Although B fertilization is the simplest and most cost-effective solution to the problem, various practical constraints prohibit its adoption by farmers cultivating low-B soils. Genetic variation in B acquisition and efficiency in biomass production is manipulated in many crop species for managing B deficiency (Rerkasem and Jamod 1997). Therefore, we studied some major rice cultivars in Pakistan for their comparative B efficiency.
