Effect of parasitizing different numbers of Cistanche deserticola on the seed yield and quality of C.deserticola
Haloxylon ammodendron and Cistanche deserticola were used to study the effect of parasitizing different numbers of C.deserticola on the seed yield and quality of C.deserticola.The results showed that:When the number of C.deserticola parasitized on H.ammodetdron per plant within the range of one to seven,with the number of C.deserticola increased:1) The biomass of H.ammodendron-C.deserticola decreased 6.1% to 10.5%.2) The accumulation of non-structural carbohydrate of H.ammodendron per plant decreased 23.2% to 30.7%,while the accumulation of non-structural carbohydrate of C.deserticola seed improved 143.8% to 331.3%.3) The seed yield of C.deserticola on H.ammodendron parasitized by C.deserticola per plant improved 170.3% to 338.1%.These findings suggested that the appropriate number of C.deserticola parasitized on H.ammodendron could improve the seed yield of C.deserticola by optimizing the distribution of non-structural carbohydrate.
