“…A number of environmental conditions can influence the growth and rooting speed of vegetative propagation including humidity [ 14 ], temperature [ 15 , 16 ], cutting length, stem thickness [ 17 , 18 ], season [ 16 , 18 ], and the age and health of mother plants [ 16 , 19 ]. Yet, there is little published data describing the effect of light, cutting method, or spatial arrangement of cuttings on the success of those cuttings.…”

“…By modifying the conditions under which clones are collected and grown, we could increase the number of clones that successful produce roots and the speed at which they do so. Basal stem wounding when combined with applications of the auxin IBA (1H-indole- 3-butanoic acid) has been shown to encourage rooting in difficult to propagate plant populations [ 14 , 15 , 20 , 21 ]. Exposure of vascular cambium and secondary xylem (i.e., wounding) to the rooting environment can be beneficial by inducing hormonal changes in plant tissues capable of producing lateral roots [ 22 ].…”

“…Jojoba ( Simmond siachinensis ) stem cuttings show roots emerging from the entire wound rather than just the base, although there is no increase in overall success or time to root [ 20 ]. Alternatively, Colutea istria displays increased rooting success and root number when wounded [ 14 ]. Some cannabis growers suggest wounding may be a useful method for enhancing rooting speed in the high-throughput production of clones.…”

“…Finally, managing water stress in soft stem cuttings is essential to encouraging rooting of clones. Previous studies have revealed that optimal relative humidity conditions for rooting are species-specific requirements [e.g., 14 , 23 ]. If wounding is not imposed, a 45° cut maximizes the contact between tissue surface area with the rooting medium.…”

The burgeoning cannabis market requires evidence-based science such that farmers can quickly and efficiently generate new plants. In part, horticultural operations are limited by the success of cloning procedures. Here, we measured the role of environmental conditions and cultivar identity on the success of generating long branch material with many meristems in planting stock (mothers) and in rooting success of stem-derived clones. To evaluate the influence of lighting treatments on the optimal production of branching mothers, four lighting conditions (Fluorescent High Output T5s [T5], Metal halide lamps [MH], Plasma lamps [PL], or Metal halide lamps augmented with far red LED lights [MH+FR]) were applied to two cultivars of container grown plants (Cannabis sativa L. ‘Bubba Kush’, ‘Ghost Train Haze’) grown in peat-based organic substrates in mylar grow tents. To evaluate the influence of lighting, cutting tool (secateurs or scalpels), and stem wounding (present/absent) on optimal rooting of stems, three lighting conditions (Fluorescent T8s, T5, PL) were applied to three cultivars of peat pellet grown plants (C. sativa L. ‘Bubba Kush’, ‘Ghost Train Haze’, ‘Headband’). Mothers grown under T5 and MH (vs MH+FR) produced ~30% more meristems. However, growing mothers under MH+FR were 19% taller than mothers under T5, with ~25% longer internodes on dominant stems than plants under any other lighting condition. Canopies were denser under T5 because petiole length was ~30% shorter under T5 and fan leaves were longer and narrower under MH+FR and MH+FR and PL, respectively, than under other lighting conditions. Cultivar Ghost Train Haze stems rooted most frequently and most quickly. Wounded stems were 162% more likely to root than unwounded stems and rooted 1.5 days earlier. Our results will guide producers attempting to maximize the rate of clone production in licensed facilities; although results may differ among cultivars, where cultivars differed in their average phenotype as mother plants, and their propensity to root from cuttings, and the speed with which they produced those roots.

“…The differential response of softwood and hardwood cuttings to different auxins might be due to different ratios of endogenous root promoting substances in each type of cuttings. This may be explained by the greater accumulation of reserves in hardwood cuttings [13].…”

Colubrina travancorica Bedd. is a medicinally important endemic plant species of Southern Western Ghats. Scientific studies are lacking due to the non availability of this Rare Endangered and Threatened (RET) species. For the conservation and establishment of C. travancorica, propagation methods have to be standardized. In the present study, propagation of the plant is achieved through hard wood cuttings, softwood cuttings and in vitro seed germination with different plant growth regulators. The type of auxins, Indole-3-acetic acid (IAA), Indole-3-butyric acid (IBA) or Naphthalene acetic acid (NAA) at varying concentrations affect the rooting response of hardwood and softwood cuttings. Significantly (p<0.001) high rooting was observed in hardwood cuttings treated with 2.5 mM IAA (53.3%). The number of roots (25.16) was significantly (p<0.001) high in cuttings treated with 0.5 mM NAA. Seasonal variation in the rooting response was observed in both hardwood and softwood cuttings. In soft wood cuttings maximum rooting (26.6%) was observed in 20 mM IBA treatment. Control set completely failed to root in the soft wood cuttings. Highest in vitro seed germination was achieved with 6.0µM Gibberellic acid. Among the various propagation methods hard wood cuttings are found to be the most suitable material for the propagation of C. travancorica and it can be effectively used for the large scale multiplication of this plant.
