- Abstract
Proteins possible effects on roots have received little attention. Here, we investigated how externally supplied protein influences root formation of Cinnamomum camphora cuttings. Cultivation matrix was composed of vermiculite, perlite and river sand based on the proportion 2 2 3. Softwood cuttings were soaked and injected by the bovine serum albumin (BSA). The results demonstrated that the addition of low to intermediate concentrations of protein ( 7.58 M BSA) increased rooting rate, average number of lateral roots and average root length of cuttings. However, the rooting rate, the number and length of lateral root decreased at higher concentrations of BSA ( 15.15 M BSA). The treatment of injection was more effective than that of soaking. The endogenous hormones (ZR, IAA, ABA, GA) content of the cuttings rapidly decreased after cutting. On the different days after cutting, four endogenous hormones decreased to the lowest value respectively. Low to intermediate concentrations of BSA will alter the content and proportion of 4 endogenous hormones and be conducive to root development. But the higher concentrations of exogenous BSA changed the content and proportion of 4 endogenous hormones was not in favor of root formation.
