Agronomic Traits and Photosynthetic Parameters of Celery Under Facility Cultivation
摘要
Abstract
To explore the differences in agronomic traits and photosynthesis-related parameters among different celery varieties and to breed celery varieties with higher yields,this experiment used seven local celery varieties such as'SQ-1'as materials and conducted uniform planting management under facility cultivation.The results showed that in terms of agronomic traits,'SQ-4'had the most small leaves,and its single plant weight and root length were also superior to other tested varieties,reaching 78.23 g and 14.08 cm respectively;'SQ-5'had the largest leaf stalk width and thickness among the tested varieties,which were 7.92 and 7.32 mm respectively,while'SQ-4'had the second largest leaf stalk width and thickness among the seven tested varieties;the average plant height of'SQ-5'was 47.07 cm,significantly higher than the other six varieties,and the average plant height of'SQ-4'was 43.22 cm,ranking third among the seven tested varieties.In terms of photosynthesis-related parameters,'SQ-1'had the highest net photosynthetic rate of 4.80 μmol/(m2·s),and'SQ-3'had a significantly higher transpiration rate than the other varieties,reaching 1.81 mmol/(m2·s).Meanwhile,the net photosynthetic rate and transpiration rate of'SQ-4'were 4.78 μmol/(m2·s)and 1.75 mmol/(m2·s)respectively,slightly lower than the maximum values among the tested varieties but still highly significant.'SQ-7'had the highest relative chlorophyll content(SPAD)of 42.93 and nitrogen content of 13.40 mg/g among the tested varieties,while'SQ-4'had the second highest SPADand nitrogen content after'SQ-7'.In conclusion,'SQ-4'has a relatively prominent comprehensive advantage in key agronomic traits such as single plant weight,number of small leaves,and plant root weight,as well as photosynthesis-related parameters.关键词
