A planting system involving a non-damaging stimulus (3) which is placed in the vicinity of a propagule (2) causes a naturally defensive substance (5) to be produced by the propagule. This substance may exist within an encapsulant (1) for a period of time so that the propagule may have enhanced disease control until it develops sufficiently to fend for itself. In one embodiment a large encapsulant surrounds a potato tuber. This encapsulant may include chitin to cause the release of chitinase through intermediate stimulants such as mRNA and activated carbon to absorb or release particular substances. The encapsulant is bound through the use of pentosan which acts with flaked chitin to achieve an outer casing and further protect the propagule both mechanically and chemically.

The invention provides a method for improving the quality of expanded cut rolled stem of tobacco by microbial enzyme. The procedures are as follows:1) Preparation of bio-enzyme: (1) Aspergillus niger is activated and cultured by potato cane sugar culture medium and is then transferred into sterilized seed culture medium, and shake cultivation is carried out at the temperature of 28 DEG C for 24 hours with 250r/min<-1>; seed liquid with 10% of inoculation amount is transferred into a sterilized 500ml shake flask (containing 100ml culture liquid for enzyme), and the seed liquid carries out incubation for culturing at the temperature of 25 DEG C for 96 hours and then zymotic liquid is obtained. (2) Extraction of lignin degradation complex enzyme: After being filtered by filter paper, the zymotic liquid is centrifugally separated at the low speed of 1500rpm. The supernatant carries out fractional salting out by (NH4)2SO4 till the saturation is 0.7 to obtain crude enzyme liquid, after the crude enzyme liquid carries out ultrafiltration dialysis, the lignin degradation complex enzyme is obtained. Activities of enzyme components: 350U/L of Lip, 11U/L of MnP and 5.6U/L of Lac; 2) Improvement of the quality of expanded cut rolled stem of tobacco: The expanded cut rolled stem for cigarette is weighed and sprayed evenly by lignin degradation complex enzyme liquid containing 0.2-0.4% of expanded cut rolled stem after being diluted by distilled water at the temperature of 27 DEG C-29 DEG C. The expanded cut rolled stem of tobacco is placed in a sealed container for enzymolysis for 95-97 hours and dried naturally till the moisture content is 12.5%-15%. The result by subjective analysis suggests that the complex enzyme preparation can effectively decrease the lignin content of the expanded cut rolled stem, promote the transformation of aroma matter and improve aroma quality and taste.
