Here's all I could find on the subject of rooting and vitamin B: It shows an increase in rooting using vitamin B in some plants, but no advantage over auxin.

ABSTRACT:
An attempt was made to test whether the improvement in seed germination percentage and seedling growth in iD. innoxia/i [iD. fastuosa/i], attained by us in an earlier iin vitro/i experiment, could be confirmed in pot culture by pre-sowin
g seeds treated with vitamins Bsub1/sub [thiamin], Bsub6/sub [pyridoxine], B complex and C [ascorbic acid] each at five concentrations (0, 250, 500, 750 and 1000 ppm) according to a factorial randomized design. Most data were highly significant (P=
0.01). Vitamins improved seed germination percentage in general, which was recorded at weekly intervals up to 35 days after sowing. Root length, shoot length, total seedling length, fresh weight, dry weight and productivity index were recorded in 35-day-ol
d seedlings. Considering all the studied parameters, vitamin Bsub6/sub proved slightly superior to B complexCBsub1/sub. Among concentrations, 500 ppm proved optimum for most parameters. Higher concentrations were !
less efficacious or even inhibitory. Vitamin Bsub6/sub at 500 ppm proved most effective, with vitamin B complex at 500 ppm being a close second.

Pages: 114-117
ABSTRACT:
With a view to mitigating transplant problems in palms, a trial was conducted on 6-month-old, self-sown seedlings of iPtychosperma lineare/i from a garden and one-year-old nursery-grown seedlings of iAcoelorraphe wrightii/i. The seedlings we
re transferred to plastic pots (57 mm square x 127 mm deep) containing a sterile, soilless potting mix, grown at moderate light levels, with high temperature and humidity and daily irrigation, and monitored weekly from 7 May to 18 August 1999. Plants in th
e experimental treatments received a 0.01% vitamin Bsub1/sub solution, either as an initial drench, a weekly drench or a weekly foliar spray (to run-off), while control plants received tap water in the same manner. By the end of the experiment, there w
ere no visible differences between control and experimental plants, although statistical analysis did reveal a few significant differences in shoot and root masses. It was concluded that the treatments in this trial would n!
ot be commercially feasible for moving nursery stock up to marketable size.

ABSTRACT:
Adventitious rooting was investigated in shoot cuttings of neem (iAzadirachta indica/i) and karanj (iPongamia pinnata/i), collected from 10-yr-old trees near Jabalpur, Madhya Pradesh, from June/July 1993 to April/May 1994. The influence of a
uxins (IAA, IBA, NAA) and B-vitamins (neem only) was evaluated. Maximum rhizogenesis coincided with the emergence of new sprouts i.e. February (neem) and March (karanj). Considering both rooting percentage and root biomass, IBA was the most effective auxin
tested. Compared with auxin free controls, IBA (1000 ppm in neem and 800 ppm in karanj) significantly increased adventitious rooting percentage (to 80 and 100%, respectively), numbers of roots and root biomass for both species. In neem, B-vitamin treatmen
t gave 40-50% rooting of cuttings. This was significantly greater than rooting for controls but equivalent to the IAA treatments. In neem, some of the cuttings treated with 2000-3000 ppm IBA had well developed root systems !
without any sprouts.

In karanj, all auxin treatments promoted sprouting. The level of total soluble sugars in the rooting zone of neem and karanj was higher in non-rooted than in rooted cuttings.

ABSTRACT:
Vitamins have been shown to markedly affect rooting of cucumber hypocotyl cuttings. Among various vitamins tested, in experiments with the cv. Japanese Long Green, ascorbic acid, smallcapL-phylloquinone, calciferol, riboflavin, thiamine mononitrat
e, cyanocobalamin, nicotinic acid and pyridoxine hydrochloride significantly promoted rooting in terms of earliness of root initiation and number of roots produced per cutting. The effects of vitamins were concentration-dependant. Folic acid was inhibitory
to rooting, but its effects were not expressed in the presence of other vitamins of the B complex group.

ABSTRACT:
The roots of [unspecified] fruit plants were immersed for 30-60 s in 0.1% heteroauxin, 0.1% heteroauxin + 0.1% vitamin B1 or 0.005% 2,4-D before planting. The treatments induced early growth and vigorous root development. The best results were obtai
ned with heteroauxin + vitamin B1, which produced an average of 4.2 active roots 6.8 mm long per 1 cm of conducting root, compared with 3.0 roots 4.7 mm in length in untreated controls.
