Embodiment 1
[0023] 1. Materials and methods
[0024] 1. Plant growth conditions and material selection
[0025] First, soak the plump seeds of sandalwood (Santalum album L.) (after removing the aril) in 2mM gibberellin solution for 12 hours, then disinfect the surface of the seeds with 3% sodium hypochlorite solution for 5 minutes, rinse with distilled water for 3 times , sow in sterile sand in pots in a nursery (ambient temperature: 27-32° C.). After the seeds germinate and the seedlings grow at least 4 leaves (it takes about 1 month to 1.5 months), move the 10cm high seedlings into a 14cm×11cm plastic container filled with a mixture of loess and humus (5:1, v / v). Pots, placed in a shady shed. After 1 month, the seedlings were cultured together with the host Artemisia annua. When the seedlings grew to more than 30 cm, the seedlings and their hosts, Artemisia annua, were transferred to a 25 cm × 30 cm cloth bag filled with a mixture of loess and humus (5:1, v / v) to continue culturing. ...
Embodiment 2
[0051] 1. Materials and methods
[0052] 1. Test materials and drugs
[0053] The sandalwood for testing was planted in 2010, and the early hosts were mainly sandalwood such as Miruihua, Jiulixiang, and Neem. The row spacing was about 2m×2m, and the test plot was a flat terrain with good drainage.
[0054] In October 2015, 44 sandalwood trees with similar growth, diameter at breast height of 6-7cm, and heartwood had not yet formed were randomly selected in the test site for testing.
[0055] The tested drugs are: 6-Benzylaminopurine (6-Benzylaminopurine, BA) (~99%), Shanghai Yika Biotechnology Co., Ltd.; Ethephon (ETH) (≥85%), Beijing Suolaibao Technology Limited; 30% H 2 o 2 (Analytical grade), Sinopharm Chemical Reagent Co., Ltd.; Calcium Chloride (>99%), Beijing Combis Technology Co., Ltd.; Methyl jasmonate (MeJ) (95%), Aladdin Reagent (Shanghai) Ltd. Each drug has two concentrations of 2mM and 4mM, and the dosage is about 400ml / time, 4 times a year. See Table 1 for r...
