Lawsonia inermis L., with medicinal and industrial applications, belongs to the family of Lythraceae and grows in warm and arid regions. This study was carried out to explore the effects of nitrogen (urea; N), phosphorous (single superphosphate; P) and potassium (potassium chloride; K) fertilizers (N: P: K, 0:0:0, 100:50:50, 200:100:100, 300:200:150 kg ha−1) on photosynthesis and growth of three henna ecotypes (such as Shahdad, Roodbar and Bam) in Kerman and Shahdad climatic conditions. The obtained results showed that photosynthesis parameters, some growth indices and biomass production improved with increase in fertilizer levels. The highest values of leaf gas exchange parameters including net photosynthesis rate, leaf stomatal conductance, and transpiration rate were obtained from Shahdad ecotype. The net photosynthesis rate, leaf area index, crop growth rate, specific leaf weight, leaf area duration, biomass duration, and dry matter production were further in climatic conditions of Shahdad. The most important variables that significantly affected henna leaf production were transpiration rate (in climatic conditions of Shahdad) and biomass duration (in both of Kerman and Shahdad climatic conditions).

氮,磷和钾水平影响指甲花(Lasonia inermis L.)生态型生长指数,叶片气体交换参数和生物量产生

无花Lawsonia inermis L.,具有药用和工业用途,属于千屈菜科,生长在温暖和干旱的地区。进行这项研究的目的是探究氮(尿素; N),磷(单一过磷酸钙; P)和钾(氯化钾; K)肥料(N:P:K,0:0:0,100:50: 50,200:100:100,300:200:150千克公顷-1)在克尔曼和沙赫达德的气候条件下研究三种指甲花生态型(如沙赫达德,罗德巴尔和巴姆)的光合作用和生长。结果表明,随着肥料水平的提高,光合作用参数,一些生长指标和生物量产量均得到提高。从Shahdad生态型获得了最高的叶片气体交换参数值,包括净光合作用速率,叶片气孔导度和蒸腾速率。在Shahdad的气候条件下,净光合速率,叶面积指数,农作物生长速率,比叶重,叶面积持续时间,生物量持续时间和干物质产量进一步增加。
