Pepper is a thermophilous and heliophilic vegetable. In China, pepper is grown in greenhouse during winter and spring under lower temperature and irradiation. In this study, we investigated the effects of low temperature and low irradiance (LTLI) on the physiological characteristics and the expression of related genes in five pepper species, Capsicum annuum(More)
One of the effective ways to address the effects of abnormal climate change on plant is to find germplasms that have better resistance to adverse environments. In this paper, we studied the responses of 5 pepper species Capsicum annuum L. (CA), C. baccatum L. (CB), C. chinense Jacquin. (CC), C. frutescens L. (CF) and C. pubescens Ruiz & Pavon (CP) as well(More)
Asian rice, Oryza sativa L., is one of the most important crop species. Genetic analysis has established that rice consists of several genetically differentiated variety groups, with two main groups, namely, O. sativa ssp. japonica kata and ssp. indica kata. To determine the genetic diversity of indica and japonica rice, 45 rice varieties, including(More)
Ca2+ has been considered as a necessary ion for alleviation of stress-induced damages in plants. We investigated effects of exogenous Ca2+ on waterlogging-induced damage to pepper and its underlying mechanisms. Pepper seedlings under stress were treated by spraying of 10 mM CaCl2. Applying exogenous Ca2+ increased the biomass of pepper leaves and roots,(More)
The aim of the study was to investigate the genetic distances and their relationships among pepper species using photosynthetic features under different stresses and genetic variability. The photosynthetic features under drought, waterlogging and low-temperature stresses, rDNA internal transcribed spacer (ITS) sequences of nuclear genome and trnH-psbA(More)
The ORF100, ORF29-TrnC(GCA) spacer, rps16 gene intron and TrnT(UGU)-TrnL(UAA) spacer of chloroplast DNA (cpDNA) of 6 photoperiod-sensitive genic male sterile (PGMS) rice, Nongken58S and its 5 derivatives, were amplified and sequenced. According to the result of ORF100 and ORF29-TrnC(GCA) spacer analysis, the cpDNA of japonica PGMS line Nongken58S was(More)
OBJECTIVE Using ITS sequence of nine species to identify counterfeiting medicine and analyse phylogenetic of Asparagus. METHODS Analysing ITS sequences by amplification, cloning,sequencing and alignment. RESULTS The length range of ITS sequence of nine species was from 711 to 748 bp, the percentage of G + C content was about 60%. The phylogenetic tree(More)
Huai Zi (HZ) is a new purple mutant of green pepper (PI 631133) that is obtained from the United States Department of Agriculture. The net photosynthetic rate (P N), chlorophyll fluorescence parameters, antioxidant substances, antioxidant enzymes, photosystem 1 (PS1) and PS2 activities were studied through methyl viologen (MV) treatment. The results showed(More)
The aim of this work was to develop a photoperiod-sensitive male sterile rice with stable sterility. We developed Changguang S, an indica rice strain, by using a short critical day length. Differences in the fertility responses of Changguang S strain pollen to temperature and photoperiod under natural and controlled conditions were studied. The results(More)
