Influence of season of the year, cutting week within a propagation cycle (number of weeks from which a stock plant has been harvested), stock plant age, and rooting compound on postpropagation cutting quality, and adventitious rooting was examined for ‘Stained Glass’ coleus (Solenostemon scutellarioides). Cuttings were of higher quality and produced more robust root systems when a propagation cycle started in summer vs. fall or spring even when cuttings were harvested from stock plants of the same age.

Abstract:
Experiments with field-grown hybrid Paradox (Juglans hindsii × J. Regia) walnut trees were conducted to assess the effects of stock plant water status, auxin application method, and the addition of spermine on adventitious root formation in stem cuttings. A 2-fold increase in rooting was noted when semihardwood cuttings were collected from dry (midday Ψw = –1.3 MPa) stock plants compared to the same trees six days later when fully hydrated (midday Ψw = –0.6 MPa). Spermine, when combined with potassium indolebutyric acid (KIBA) and applied as a quick dip, enhanced the rooting percentage in hard

Abstract Greenwood cuttings from greenhouse-produced tamarack seedlings and 3- to 10-year-old tamarack wildlings transplanted from natural stands in north-western Ontario were rooted under mist in peat-vermiculite. Eighty-five percent of cuttings from seedlings rooted; treatment with indolebutyric acid increased number of roots per cutting, but not rooting percent. At 6 weeks after planting, rooting of cuttings from wildlings averaged 66%, and at 12 weeks, 91%. Twelve-week rooting percent of cuttings from individual ortets ranged from 12 to 100, but cuttings from the majority of ortets exhibit

Abstract The benefits from root colonization by mycorrhizal fungi are thought to be highest when colonization occurs as early as possible during plant growth. We assessed whether addition of VA mycorrhizal fungi (VAMF) inoculum into rooting medium during cutting propagation would increase the quantity of rooting and the quality of rooted cuttings for five different cultivars of miniature roses (Rosa spp.). Four weeks after cuttings were stuck, the number of cuttings with roots for two cultivars that normally take longer to root, increased with addition of VAMF inoculum into the rooting medium.

However, problems such as poor rooting and restrict market availability for superior clones have been a problem in vegetative propagation of the Lavandula species.
