Increasing commercial demands from the textile and food industries are putting strong pressure on the cultivation of cotton and its derivatives to produce high yields. At the same time, cotton has high nutrient and irrigation requirements and is highly susceptible to insect pests. Coating cotton seeds with beneficial fungi could address these problems. The aim of this study was to investigate the growth of cotton using (A) conventional seeds and (B) seeds coated with the entomopathogenic fungus (Hypocreales: Cordycipitaceae). The experiment was conducted in a greenhouse of the Department of Agriculture of the University of Ioannina, in a completely randomized design. The growth characteristics of cotton plants were recorded weekly while the fresh weight and dry matter of the leaves, shoots and roots of the developed cotton plants were calculated at the end of the experiment. Weekly determination of total chlorophyll content (TCHL) was used as an indicator of plant robustness during the 80-day experiment. Many cotton growth parameters of treated plants, like number of leaves, shoots and apical buds, plant height, stem diameter, fresh and dried biomass and TCHL, were significantly higher than those of the untreated ones. Apart from plant growth, naturally occurring by (Hemiptera: Aphididae) infestation which also monitored for six weeks. A significantly lower aphid population was recorded for inoculated plants after the fifth week compared to the control. The overall evaluation revealed that coating treatments appear to have a significant biostimulatory and bioinsecticidal effect. Our results could represent responsive applications to the demands of intensive cotton growing conditions.
纺织和食品行业不断增长的商业需求给棉花及其衍生物的高产种植带来了巨大压力。与此同时，棉花对养分和灌溉的需求很高，且极易受到虫害影响。用有益真菌包衣棉花种子可以解决这些问题。本研究的目的是调查使用（A）常规种子和（B）用昆虫病原真菌（肉座菌目：虫草科）包衣的种子种植棉花的生长情况。该实验在约阿尼纳大学农业系的温室中进行，采用完全随机设计。每周记录棉花植株的生长特征，并在实验结束时计算发育成熟的棉花植株叶片、茎和根的鲜重和干物质重量。在为期80天的实验中，每周测定总叶绿素含量（TCHL）作为植物健壮程度的指标。处理过的植株的许多棉花生长参数，如叶片、茎和顶芽数量、株高、茎直径、鲜干生物量和TCHL，均显著高于未处理的植株。除了植物生长情况外，还对自然发生的（半翅目：蚜科）虫害进行了为期六周的监测。与对照相比，接种植株在第五周后记录到的蚜虫数量显著减少。总体评估表明，包衣处理似乎具有显著的生物刺激和生物杀虫作用。我们的结果可能代表了对集约化棉花种植条件需求的响应性应用。
