温室与大棚中不同蓝莓品种的生长生理特性比较

Growth and physiological characteristics of blueberry among different cultivars in plastic greenhouses and artificial heating greenhouses

为了解不同蓝莓品种在温室和大棚中的生长差异,以4个蓝莓品种(‘蓝丰’‘伯克利’‘莱克西’‘布里吉塔’)为试材,分析了植株的生长生理特性。结果显示,在温室中‘伯克利’的新梢最长、茎最粗、单株叶面积最大、叶绿素a、b和类胡萝卜素含量最高,‘莱克西’新梢最短、茎最细、单株叶面积最小,但叶片最厚。大棚中,‘伯克利’新梢最长、叶片最厚、单株叶面积最大,‘莱克西’新梢最短,‘布里吉塔’叶绿素a和b、类胡萝卜素含量最少。总之,温室和大棚中,均以‘伯克利’表现最好。

In order to understand growth differences of different blueberry cultivars between plastic greenhouses and artificial heating greenhouse,the growth and physiological indexes of four varieties of blueberry(‘Bluecorp’‘Berkeley’‘Laikexy’‘Brigitta’)were analyzed.The results showed that the indexes of‘Berkeley’were the highest in the artificial heating greenhouse,including the longest new shoot,the thickest stem,the largest leaf area of single plant,the highest content of chlorophyll a,b,and carotenoids.‘Laikexy’possessed the shortest shoots,the thinnest stem,the smallest leaf area and the thickest blade.In the plastic greenhouse,the longest shoots,the thickest blade,the largest leaf area of single plant belonged to‘Berkeley’.The new shoot of‘Laikexy’was shortest,and its content of Chlorophyll A,B,and carotenoids of‘Brigitta’was the lowest.To sum up,the blueberry plants grow better in heating greenhouses,with‘Berkeley’best suitable for cultivation in greenhouse.
