栽培基质对丝瓜幼苗生长及叶绿素荧光特性的影响
The effects of culture substrates on towel gourd seedling growth and characteristics of chlorophyll fluorescence
摘要
Abstract
The cultivar Min-Zao-1-Hao of towel gourd (Luffa cylindrica L.) and five culture substrates (peat, perlite, vermiculite, coconut chaff, and river sand) were involved in a greenhouse study.The effects of six different combinations (CK, M1, M2, M3, M4, and M5) of culture substrates on towel gourd seedling growth and chlorophyll fluorescence parameters were investigated.The results showed that when the culture substrate was composed of equal volumes of peat and coconut chaff (M4), the best values of growth index, root/shoot ratio, G value, root activity, superoxide dismutase (SOD) activity, soluble sugar and protein contents, chlorophyll content, and chlorophyll fluorescence parameters were observed.In addition, the malondialdehyde (MDA) content was lower than those grown on five other combinations of culture substrates.Based on the morphological and physiological indexes and chlorophyll fluorescence parameters, it was concluded that the M4 culture substrate combination, i.e., equal volumes of peat and coconut chaff, was an optimum growth medium for towel gourd seedlings.关键词
