Cannabis growing. Grafting.
Intergeneric grafts between cannabis and Humulus ( hops ) have fascinated analysts and cultivators for years. Warmke and Davidson ( 1943 ) claimed that Humbles tops grafted on cannabis roots produced “. As much drug as leaves from intact hemp plants, although leaves from intact hop plants are utterly nontoxic. ” According to this research, the active constituent of cannabis was being produced in the roots and transported across the graft to the Humulus tops. Later research by Crombie and Crombie ( 1975 ) completely disproves this speculation. Grafts were made between low and high THC strains of cannabis as well as intergeneric grafts between cannabis and Humulus, Detailed chromatographic research was performed on both donors for each graft and their control populations. The results showed “. No proof of transport of inter mediates or factors important to cannabinoid formation across the grafts. ” Grafting of cannabis is simple.
A few seeds can be grafted together into one to provide terribly fascinating example plants. One process starts by planting one seed ling each of a few separate strains close together in the same container, putting the stock ( root plant ) for the cross in the middle of the rest. When the sprouts are 4 weeks old they’re prepared to be grafted. A diagonal cut is made roughly half-way thru the stock stem and one of the scion ( shoot ) sprouts at the same level. The cut portions are slipped together such the inner cut surfaces are touching. The joints are held with a fold of cellophane tape. A second scion from an opposite seedling might be grafted to the stock higher up the stem. After 2 weeks, the unwelcome portions of the grafts are cut away. 8 to 12 weeks are wanted to complete the graft, and the plants are maintained in a mild environment at every point. As the graft takes, and the plant starts to grow, the tape falls off.
