摘要

生长环境中可用的太阳辐照量会引起生理和叶片解剖的显著变化,使作物能够适应不同的光照条件。在这种意义上,目的是表征叶片解剖特征,并阐明半干旱条件下heliconia基因型在发育初期适应高太阳辐照的形态生理机制。试验在巴西伯南布哥州的佩特林纳市(09°19 ' 14 " S, 40°32 ' 40 " W,海拔387 m)进行,研究了三种向日葵基因型(heliconia rauliniana;H.比海cv。在全光照和遮阳(50%)环境下生长的龙虾爪2号和rostrata。试验实施后30 d,分析叶片解剖、叶绿素指数、株高、叶片数和分蘖数。向日葵叶片具有两形气孔和四胞气孔的特征。在其主静脉的背面和正面有通气组织和皮下组织。碧海、水蛭和rostrata三种植物对不同光照条件的响应具有基因型特异性。此外,在海螺和海螺中观察到的解剖结构和生理变化表明,这些基因型具有更大的可塑性,因此更有可能适应高太阳辐照条件。因此,基因型H. rauliniana和H. bihai作为一种潜在的替代植物在花园或开阔地区种植,并在太阳辐照度高的地区作为切花进行探索。

Leaf anatomy and morpho-physiological mechanisms of acclimation to high irradiance in heliconia genotypes
ABSTRACT The amount of solar irradiation available in the growing environment can cause significant changes in physiology and leaf anatomy that enable crops to acclimate to different light conditions. In this sense, the objective was to characterize the leaf anatomy and to elucidate the morpho-physiological mechanisms of acclimation to high solar irradiance of heliconia genotypes during the initial stage of development under semiarid conditions. The experiment was conducted in the municipality of Petrolina, Pernambuco state, Brazil (09° 19’ 14” S, 40° 32’ 40” W, and 387 m of altitude) and the behavior of three heliconia genotypes (Heliconia rauliniana; H. bihai cv. Lobster Claw Two, and H. rostrata) grown in full sun and shading (50%) environments were evaluated. At 30 days after the implementation of the experiment, leaf anatomy, chlorophyll index, plant height, number of leaves, and number of tillers were analyzed. Heliconia leaves are characterized as amphistomatous with tetracytic stomata. In its main vein there are aerenchyma structures and hypodermis on the abaxial and adaxial sides. The responses to different light conditions in plants of H. bihai, H. rauliniana, and H. rostrata are genotype-specific. Furthermore, the anatomical structures and physiological changes observed in H. bihai and H. rauliniana plants demonstrate that these genotypes present greater plasticity and consequently greater potential for acclimation to high solar irradiation conditions. Thus, the genotypes H. rauliniana and H. bihai emerge as a potential alternative for cultivation in gardens or in open areas and for exploration as cut flower in regions with high solar irradiation availability.
