肥料管理是药用植物种植成功与否的重要因素，在确定肥料对环境的生存力和对植物的适宜性之间，可以对植物的数量和质量指标产生理想的影响。为了研究化学和生物肥料对甜罗勒（Ocimum basilicum L.）的影响，于2010年在大不里士大学温室进行了试验。采用对照（T1）、化学肥料（T2）、生物肥料（T3）和化学与生物肥料组合（T4） 4个水平的2种肥料（化学与生物）和2个地方品种罗勒（大不里士和马赞达兰）进行评价。试验采用随机完全区组设计，共3个重复。移栽时接种生物肥处理，发芽和坐定时施用化肥。试验结果表明，施用生物肥显著提高了叶绿素(a)和叶绿素(b)浓度（2.929 mg/g.f.w）。T)和（1.788 mg/g.f.w）。T)，且生物肥处理的叶面积和氮密度最高，分别为233.5 cm2和4.84%。结果表明，叶绿素b密度与叶绿素a密度（r = 0.99**）和氮密度（r = 0.92**）呈高度相关。结果表明，生物肥料可作为甜罗勒的替代肥料。施氮率与叶面积、叶绿素a、b密度呈显著正相关，施氮率越大，叶面积、叶绿素a、b密度越大。由于叶绿素b转化为叶绿素a，降低了叶绿素b与叶绿素密度之比。*通讯作者：Samane Bakhshande Larimi (sb_farming@yahoo.com International Journal of Biosciences | IJB | ISSN: 2220-6655 (Print) 2222-5234 (Online) http://www.innspub.net Vol. 5, No. 9, p. 256-265, 2014
Management of fertilizer was successful major factor in the planting of medicinal plant and in between identification of consistence fertilizers viability to environment and suitable for plant can be desired effects on the quantity and quality plant indexes. In order to study of chemical and bio-fertilizer effects on Sweet Basil (Ocimum basilicum L.) was experiment in the year 2010 in green house of Tabriz University. Two kinds of fertilizer (chemical and biological) at four levels (control (T1), chemical fertilizer (T2), biological fertilizer (T3) and combination of chemical and biological fertilizers (T4)) and two landraces of basil (Tabriz and Mazandaran) were evaluated. Experiment was factorial based on randomized complete block design in three replications. Biological fertilizer treatment was inoculated in the time of implanting and chemical fertilizer was used in the time of germination and setting. Results of experiment was suggested that use biofertilizer chlorophyll (a) and (b) concentration was increased significantly (2.929 mg/g.f.w.t) and (1.788 mg/g.f.w.t) respectively and the highest value of leaf area (233.5 cm2) and nitrogen density (4.84%) obtained in biofertilizer treatment. According to results high correlation was toward chlorophyll b density with chlorophyll a density (r = 0.99**) and nitrogen density (r = 0.92**). The results showed that biofertilizer can be raised as an alternative chemical fertilizer in Sweet Basil. Also positive relations was shown between percent nitrogen with leaf area, chlorophyll a and b density, that with increased percent nitrogen increases leaf area and chlorophyll a and b density. Also because of conversion chlorophyll b to chlorophyll a, decreases chlorophyll b density ratio to chlorophyll density. * Corresponding Author: Samane Bakhshande Larimi sb_farming@yahoo.com International Journal of Biosciences | IJB | ISSN: 2220-6655 (Print) 2222-5234 (Online) http://www.innspub.net Vol. 5, No. 9, p. 256-265, 2014
