梅花的叶片每到夏季就会自然卷曲,甚至泛黄早落,这往往给人的感觉是缺水,但实际上盆土并不干。经调查,也非病菌浸染所致,而是与其本身的结构密切相关的。根据实验结果分析,可看出梅花与桃、杏在输水与耗水结构上以及叶片耐旱能力上有差别。见下表:从表中可以看出梅与桃、杏相比,其输导组织结构与耗水组织结构不协调,气孔调节能力差,耐旱力差,以致叶片产生严重的水分亏缺,导致叶片卷曲。其叶片向上卷是因为梅叶上表皮层细胞特大及叶片厚,水分亏缺后上表皮细胞失水较多,体积缩小,因此表现为叶片向上卷曲而不是萎蔫。 Plum leaves every summer will naturally curly, and even yellowing early fall, which often gives the impression that water shortages, but in fact basin soil does not dry. After investigation, but also caused by non-pathogenic bacteria, but with its own structure is closely related. According to the analysis of the experimental results, it can be seen that plum, peach and apricot are different in water and water consumption structure and drought tolerance of the leaves. See the table below: As can be seen from the table plum and apricot, compared with the organization of its tissue structure and water consumption is not coordinated, stomatal regulation is poor, poor drought tolerance, resulting in severe water deficit leaves, Leaves the leaf curled. The leaves are rolled up because the plum leaf cells on the epidermis and leaf thick, water deficit epidermal cells after dehydration more volume shrinks, so the performance of the leaves curl up rather than wilting.
