| Abstract: |
| In…order…to…research…the…effects…of…harvest…maturity…on…yield…and…quality…characteristics…of…middle…and…
upper…leaves…of…flue-cured…tobacco…NC297…and…NC102， the…appearance…quality， economical…characteristics， chemical…
components…of…cured…tobacco…leaves…with…different…harvest…maturity…were…studied.…The…results…showed…that…harvested，
in…26…d…after…topping， there…were…the…best…economic…traits…and…appearance…quality…for…middle…leaves…of…both…this…two…
cultivars.…and， there…were…the…harvested…in…47…d…after…topping…best…appearance…quality…for…the…upper…leaves…of…the…two…
cultivars， while…harvested…in…54…d…and…47…d…after…topping， there…were…the…best…economic…traits…for…flue-cured…tobacco…
NC297…and…NC102， respectively.…In…the…main…chemical…components， the…middle…leaves…harvested…in…20…d…after…topping…
of…flue-cured…tobacco…NC297…were…more…harmonious， which…accorded…with…that…obtained…by…the…local…practice， and…in…
26…d…after…topping…for…the…flue-cured…tobacco…NC297； while…in…54…d…and…47…d…after…topping…for…the…upper…leaves…of…NC297…
and…NC102， respectively.…It…was…concluded…that…the…optimum…harvest…time…was…26…d…after…topping…for…the…middle…leaves…of…
the…two…cultivars， while…54…d…and…47…d…after…topping…were…the…suitable…harvest…time…for…upper…leaves…of…flue-cured…tobacco…
NC297…and…NC102， respectively. |
