Abstract:
Using the tender stems of the ‘Fangio’ lily as explants,the method of tissue culture was used,the effects of different disinfectant concentrations,disinfection times,and different hormone concentration ratios on the in vitro induction of ‘Fangio’ bulbils were studied.Using ‘Fangio’ as the test materials,in the greenhouse of the test base,the topping of the plants grown in the open field was combined with the spraying of paclobutrazol or chlormequat,the induction of bulbils on the plants were studied,in order to provide a reference for improving the efficiency of ‘Fangio’ bulbils by the two methods.The results showed that the optimal disinfectant concentration and time were immersed in 1% NaClO for 10 minutes;the optimum medium for ‘Fangio’ to induce bulbils was MS+0.5 mg?L-1 6-BA+0.3 mg?L-1 NAA+90 g?L-1 sucrose.The induction rate of bulbils in different parts of the same plant was upper>middle>lower;studies on the upper stem segments at different developmental stages showed that the plants in the vegetative growth stage were the most suitable for in vitro induction of bulbils.The traumatic induction experiment was carried out on the ‘Fangio’ of natural growth.It was found that the best period for the topping treatment was the beginning of the bud;the best induction method was to spray the paclobutrazol on the plant at the same time as the topping.
