霍霍巴(jojoba)Simmondsia chinensis的种子含有与鲸蜡油基本相似的蜡状物,是一种有希望的植物。为了寻找鲸蜡油的代用品,对其进行了研究。霍霍巴是雌雄异株的植物,用播种方法繁殖往往雄株偏多,而且播种后2—4年开花时才能辨别出来。密播虽能保证雌株有适当密度,但由此而引起的株间竞争却阻碍其发育,延缓其生长。因此,要发展霍霍巴这种经济作物,就需要改进繁殖和培育的方法,同时,还要选择具有优良性状(如种子产量、含蜡量及抗病性等)的无性系。但是关于霍霍巴无性繁殖方面的资料为数甚少。为了确定霍霍巴扦插生根所需要的某些条件,我们对植株个体生根力的变异、插穗的采集季节以及植物生长刺激素对生根的影响进行了探讨。
Jojoba The seed of Simmondsia chinensis contains a wax that resembles whale oil and is a promising plant. In order to find alternatives to sperm oil, it was studied. Jojoba is a dioecious plant that grows more often with sowing methods than male plants, and can be distinguished when it blooms 2-4 years after sowing. Although sowing can ensure that the female plants have the proper density, the competition caused by the strains hinders their growth and slows their growth. Therefore, in order to develop such economic crops as Jojoba, we need to improve breeding and breeding methods, and at the same time, we must choose clones with excellent traits (such as seed yield, wax content and disease resistance). However, there is very little information on the clonality of Jojoba. In order to determine the conditions for the rooting of Jojoba cuttings, we studied the variation of rooting ability, the season of cuttings collection and the effect of plant growth hormone on rooting.
