disparity in the germination time of argan nuts (argania spinosa l. skeels) on the growth of their seedlings in nurseries

The challenges encountered for the propagation of the argan tree are embryonic and integumentary dormancy, which directly affect the rate and the duration of germination, the standards of aggregation of the plants for the reforestation, and in parallel on the stay time in the nursery. the study was conducted on argan tree (argania spinosa (l) skeels) seedlings from two types of experimental germination of the kernels in the nursery: one pre-treatment with hot water and the second without pre-treatment (control). the aim was to see the effect of the duration of germination on the growth of the seedlings. the argan nuts germinating for a short time gave rise to plants of almost convergent height (varying from 23 to 25 cm), i.e., the average height was very representative and similar to the height of their plants (24.94 cm). on the other hand, the nuts with a long germination period produced seedlings of varying heights (ranging from 09 to 27 cm), with an average height different from their range of seedlings (17.46 cm). regarding diameter growth, germination time did not affect young plants. when the germination period was short, it was possible to obtain homogeneous seedlings that met phyto-technical standards for reforestation. according to this study, argan seedlings should not be kept in the nursery for more than 33 weeks (8 months); otherwise, there is a risk of a poorly formed root system.
