中文摘要：
以梭梭和肉苁蓉为试验材料，研究了梭梭树龄与肉苁蓉种子产量的关系。结果表明：1）梭梭基径粗、株高、冠幅、肉苁蓉直径、花序长、蒴果数、有效果数、单蒴果重和单株种子产量与梭梭树龄呈显著正相关，相关系数在0．93以上。2）随着梭梭树龄增长，与对照相比，单株肉苁蓉种子产量提高了2～5倍。直径〈0．5mm的种子所占比例下降，直径为0．5～0．7mm种子所占比例提高。3）5年生及以上的梭梭所寄生的肉苁蓉直径和花序长可达21．72mm和30．8cm以上，并且蒴果数、有效果数和单株种子产量分别可达143个、128个和11．810g以上。5年生及以上的梭梭可作为寄主培育肉苁蓉留种植株。
英文摘要：
To study the relationship between the seed yield of Cistanche deserticola and the age of Haloxylon ammodendron, three to six years old H. ammodendron parasitized by C. deserticola were selected and the seed yield, the yield components of C. deserticola were measured. The results showed that： （1） The base diameter, the height and crown of H. ammodendron, the base diameter and inflorescence length of C. deserticola, total number of capsules, number of effective capsules,single capsule weight and seed yield per plant were interrelated significantly with the age of H. ammodendron and the correlation coefficients were above 0.93; （2） compared with the control and the growth of H. ammodendron （from three years to six years old）,the seed yield per plant increased 2- 5 times, the proportion of the seed diameter declined less than 0.5 mm,and the seed diameter increased around 0.5 to 0.7 mm; （3） the base diameter and inflorescence length of C. deserticola, the total number of capsules,the number of effective capsules,the single capsule weight and the seed yield per H. ammodendron plant of five years old and above parasitized by C. deserticola were increased more than 21. 72 mm, 30. 8 cm, 143, 128 and 11. 810 g respectively. Therefore, H. ammodendron with five years old and above could be used as the host plants of C. deserticola for seed production.
