摘要:

为进一步掌握德阳雪茄主栽品种特性,采用SPAD 502叶绿素仪对4个当地主栽品种大田生育期叶绿素含量进行测定,分析不同品种、不同时期、不同叶位、不同位置叶绿素含量变化。结果表明,4个品种整体叶绿素含量两两相近,‘德雪五号’和‘德雪七号’高于‘德雪一号’和‘德雪三号’,在大田期的叶绿素含量变化均为先升高后降低,在移栽后37天左右达到最高点,移栽后82天左右为最低点,不同品种不同叶位叶绿素含量均随叶位上升而上升,叶片不同位置叶绿素含量均呈叶尖>叶中>叶基的规律。其中‘德雪七号’在打顶后叶绿素含量呈现一定特异性,‘德雪一号’、‘德雪五号’与‘德雪三号’、‘德雪七号’进入成熟期时间点相差约13天。试验结果反映了4个雪茄品种在大田生育期叶绿素含量变化规律,为生产管理、烟叶采收等提供了理论依据。

Abstract:

To clarify the characteristics of main cigar varieties in Deyang, SPAD 502 chlorophyll meter was used to determine the chlorophyll content of four local main varieties during the field growth period, and the changes of chlorophyll content in different varieties, different periods, different leaf positions and different positions on leaf were analyzed. The results showed that the total chlorophyll content of the four varieties were similar. The chlorophyll contents of ‘Dexue 5’ and ‘Dexue 7’ were higher than those of ‘Dexue 1’ and ‘Dexue 3’. The content of chlorophyll increased first and then decreased in field growth period, and reached the highest point about 37 days after transplanting, and the lowest point was found 82 days after transplanting. The chlorophyll content in different leaf positions of different varieties increased with the increase of leaf position, and the chlorophyll content of different positions on leaf showed the rule of leaf tip> the middle of leaf > leaf base. After topping, the chlorophyll content of ‘Dexue 7’ showed a certain specificity, and there was a time difference of entering maturity for about 13 days among ‘Dexue 1’, ‘Dexue 5’ with ‘Dexue 3’ and ‘Dexue 7’. The results show the change rule of chlorophyll content of the four cigar varieties during the field growth period, and can provide a theoretical basis for production management and tobacco harvest.
