[QUOTE="cannebosanac, post: 20021, member: 1357"] poglavlje 2 nastavak Layers often seem rejuvenated when they are re- moved from the parent plant and begin to be supported by their own root systems. This could mean that a clone will continue to grow longer and mature later than its parent under the same conditions. Layers removed from old or seeded parents will continue to produce new calyxes and pistils instead of completing the life cycle along with the parents. Rejuvenated layers are useful for off-season seed production. Grafting Intergeneric grafts between Cannabis and Humulus (hops) have fascinated researchers and cultivators for decades. Warmke and Davidson (1943) claimed that Humu- lus tops grafted upon Cannabis roots produced ". . . as much drug as leaves from intact hemp plants, even though leaves from intact hop plants are completely nontoxic." According to this research, the active ingredient of Canna- bis was being produced in the roots and transported across the graft to the Hum ulus tops. Later research by Crombie and Crombie (1975) entirely disproves this theory. Grafts were made between high and low THC strains of Cannabis as well as intergeneric grafts between Cannabis and Humu- lus, Detailed chromatographic analysis was performed on both donors for each graft and their control populations. The results showed ". . . no evidence of transport of inter- mediates or factors critical to cannabinoid formation across the grafts." Grafting of Cannabis is very simple. Several seedlings can be grafted together into one to produce very interesting specimen plants. One procedure starts by planting one seed- ling each of several separate strains close together in the same container, placing the stock (root plant) for the cross in the center of the rest. When the seedlings are four weeks old they are ready to be grafted. A diagonal cut is made approximately half-way through the stock stem and one of the scion (shoot) seedlings at the same level. The cut por- tions are slipped together such that the inner cut surfaces are touching. The joints are held with a fold of cellophane tape. A second scion from an adjacent seedling may be grafted to the stock higher up the stem. After two weeks, the unwanted portions of the grafts are cut away. Eight to twelve weeks are needed to complete the graft, and the plants are maintained in a mild environment at all times. As the graft takes, and the plant begins to grow, the tape falls off. Pruning Pruning techniques are commonly used by Cannabis cultivators to limit the size of their plants and promote branching. Several techniques are available, and each has its advantages and drawbacks. The most common method is meristem pruning or stem tip removal. In this case the growing tip of the main stalk or a limb is removed at approximately the final length desired for the stalk or limb. Below the point of removal, the next pair of axial growing tips begins to elongate and form two new limbs. The growth energy of one stem is now divided into two, and the diffusion of growth energy results in a shorter plant which spreads horizontally. [/QUOTE]
