Jacaranda mimosifolia of 55-year-old in Sichuan Neijiang was selected as test material. Through the observation of its growth and development by 2011 and the analysis of temperature and relative humidity, this study discussed its basic law of growth and development and the relationship between temperature and RH factor. By analysis of variance, there was no significant difference in monthly average temperature and RH between 2011 and the climate in Neijiang, the temperature and RH of 2011 could reflect the situation of Neijiang regional climatic. The results showed that the average annual growth of J. mimosifolia new shoot was 32.4cm and the average thickness was 11.2mm, and appeared thrice sprouting and twice flowering phenomenon per year. Combined the characteristics of growth and development of J. mimosifolia, the length and thickness of spring shoot, summer shoot and autumn shoot were both extremely different (P<0.01), and two florescence appeared in Spring and Autumn when the temperature was not different significantly. Therefore, temperature played an apparently predominant role in its growth and development.

“…However, the type of fruits and their conservation time affect the germination capacity of the seeds, according to Póvoa (2018), who observed germination results ranged from 11.3% (dark brown old fruits) to 93.5% (light brown, new fruits). Other methods of propagation of Jacaranda mimosifolia include the addition of GA3 to immature seeds of Jacaranda mimosifolia (Miyajima et al, 2005) and thermal treatments to the seeds (Póvoa, 2018). Works on the application of laser and its effect on the germination of this species of Prosopis and other woody species including Jacaranda mimosifolia are lacking.…”

“Jacaranda” (Jacaranda mimosifolia) and "mezquite” (Prosopis laevigata) are timber species that generally present problems with regard to the germination of their seeds in natural conditions, since they have a very hard and impermeable cover. Different treatments have been applied to improve the germinative response of both species with unfavorable results. This study aimed to know the effect of the pre-sowing laser biostimulation on germination and seedlings growth of these species. The seeds were biostimulated with a He-Ne laser (632 nm, 10 mW). Considering three replications of 50 seeds for each species, five irradiation treatments were applied (30 s, 60 s, 90 s, 120 s, 150 s) and control. The results for mezquite demonstrated that the highest number of germinated seeds (96%) was obtained with the treatments 90 s and 150 s; in contrast, the control seeds showed a lower germination percentage (16%). Additionally, the 30 s treatment produced a positive effect on the growth of the root, and it was different (p < 0.05) to the remaining treatments and the control. For Jacaranda, there were significant statistical differences (p < 0.05) between the control and the different treatments. 29% of seed germination occurs without any treatment. However, for 90 s and 120 s, germination is induced in a relatively high percent (97%-99%). For both species, the best treatment was 120 s, since higher values were recorded for all the morphological variables. It is concluded that laser biostimulation can produce beneficial effects on the germination of seeds and seedling growth and it could contribute to the propagation and conservation of these species.

Growth and mineral absorption of ornamental woody plant such asJacaranda mimosifolia D. Don., in gnotoxenic conditions out of a mycorrhization by a commercial inoculum containing Glomus irregulare were studied. Used Jacaranda plants are one-year old, they were first grown, in 10/12cm caliber pots then in 16/18cm caliber pots for 6 months in a sterile substrate consisting of 2/3 commercial peat and 1/3 sand. Four treatments, achieved three times, were processed. Apart from the control, two other treatments consisted of the addition of commercial inoculum containing Glomus irregulare to the culture substrate, at a rate of 62.5 mg / plant for the first and 100 mg / plant for the second. These quantities respectively correspond to 100 propagules / plant and 160 propagules / plant. The fourth treatment is illustrated by the incorporation of 4g/plant of OSMOCOT EXACT standard-Scotts fertilizer; 15 + 9 + 12 (+2.5), into the substrate. Mycorrhization rate of inoculated plants by 100mg/plant dose reached 43.21% while it only reached 21.48% for those that received 62.5mg/plant. Colonization remains at the beginning of installation presenting essentially mycorrhizal hyphae structures. Mycorrhization significantly improves nitrogen, phosphorus and potassium nutrition of Jacaranda. This result in a stimulation of plant growth Level of mycorrhization by 21.48%, and achieve gains of aerial dry biomass of about 45.5% and root volume of about 46.29%. When the level of mycorrhization is equal to 43.21%, these gains correspond to, respectively, 59.1% and 67.28%. Fertilization provides for gains of 29.58% in aerial dry biomass and 9.69% in plants height. It has no effect on roots volume.
