A Brief Report on Dynamic Observation of Dry Matter Accumulation in Flue-cured Tobacco

Each flue-cured tobacco variety has three～four leafing peaks,they were 25 d,32 d,40 d,50 d after transplanting sepa-rately,the rosette stage of faint-scent type lines C2 and F1-35 is longer,the amount of dry matter accumulation is more at prophase,a-mong these varieties,the total amount of dry matter accumulation in C2 is more than others,but fertilization level is lower,it belongs to high efficient varieties of less westment and better profits,and should therefore be researched and popularized.
