VEGETATIVE PROPAGATION IN JADE TREE USING ROOTING BIOSTIMULATORS OF STEM CUTTINGS
The present study analyzed the influence of some bioactive substances on vegetative propagation based on stem cuttings of Crassula ovata (Miller) Druce (jade tree). Stem cuttings were taken from the source plants for vegetation propagation. The cuttings were 5 cm long, 0.6 cm in diameter and had two...

| description | The present study analyzed the influence of some bioactive substances on vegetative propagation based on stem cuttings of Crassula ovata (Miller) Druce (jade tree). Stem cuttings were taken from the source plants for vegetation propagation. The cuttings were 5 cm long, 0.6 cm in diameter and had two pairs of leaves, with a high degree of uniformity. Three biostimulant products were used, Raiza, Rhyzo and Sangral, along with a control variant (Ct). A peat substrate, Klasmann TS3, was used for rooting. The cuttings treated with the biostimulating products and those from the control variant were placed on the rooting substrate on June 16, 2022. The number of roots (RN) and the length of roots (RL) were evaluated at three times during the study period; June 30 (t1), July 7 (t2) and July 14 (t3). The variation of RN and RL in relation to time (days) during the study period was described by polynomial equations of the 2nd degree, under statistical safety conditions (p<0.01). According to PCA, PC1 explained 60.665% of variance, and PC2 explained 26.216% of variance. Associated with the Sangral product were RN-t2 and RN-t3 parameters, and associated with the Raiza and Rhyzo products were RN-t1 parameters and especially root length, RL-t1, RL-t2 and RL-t3. Under the aspect of the increase in the formation of the number of roots, based on the recorded values, it was found that the Sangral product generated a stronger rooting (RN-t2-I = 4.92; RN-t3-I = 3.25), and with regard to the length of the roots (RL), the Rhyzo product generated the largest increases (RL-t2-I = 1.03 cm, respectively RN-t3-I = 1.49 cm). |
