Abstract

Plants exhibit morphological plasticity in response to changes in the proportion of far-red radiation (FR). However, little is known about the response to a sudden increase of FR component. Cucumber seedlings were acclimatized to radiation without FR (FR-) for 1 - 5 d after germination, and then transferred to radiation containing FR (FR+) at levels similar to those in natural sunlight. Other seedlings were acclimatized to FR-or FR+, which was maintained continuously. The sudden increase in FR damaged the cotyledons and the first true leaf, especially when radiation was changed from FR-to FR+ at days 3 or 4 after germination. Necrosis of the damaged leaves may have resulted from inhibition of water flow in leaf xylem, because wilting and decreased stomatal conductance were observed simultaneously with leaf necrosis. Plants in the treatment groups that showed the most frequent damage showed two peaks in cotyledon elongation. This suggests that the leaves that had been acclimatized to FR-were easily damaged by the sudden promotion of leaf expansion caused by FR+.

辐射引起黄瓜叶片坏死,远红色成分突变
植物对远红辐射(FR)比例的变化表现出形态可塑性。然而,对FR成分突然增加的反应知之甚少。黄瓜幼苗在萌发后1 ~ 5d先适应不含FR-的辐射,然后转入含FR+的与自然光照水平相近的辐射环境。其他幼苗则适应FR-或FR+,并持续维持。FR的突然增加对子叶和第一片真叶造成损伤,特别是在发芽后第3天或第4天,FR+的辐照变化更明显。受损叶片的坏死可能是由于木质部的水流受到抑制,因为在叶片坏死的同时还观察到枯萎和气孔导度下降。在损伤最频繁的处理组中,子叶伸长有两个高峰。这说明已经适应FR-的叶片很容易受到FR+突然促进叶片膨胀的伤害。

期刊介绍: BIOLOGIA PLANTARUM is an international journal for experimental botany. It publishes original scientific papers and brief communications, reviews on specialized topics, and book reviews in plant physiology, plant biochemistry and biophysics, physiological anatomy, ecophysiology, genetics, molecular biology, cell biology, evolution, and pathophysiology. All papers should contribute substantially to the current level of plant science and combine originality with a potential general interest. The journal focuses on model and crop plants, as well as on under-investigated species.
