温度对生姜生长及根茎产量和营养品质的影响OA

To investigate the effects of different environmental temperatures on the growth and development of ginger plants,'Shannong No.1'ginger was used as the experimental material.Three day/night temperature treatments were established:22℃/16℃(T1),27℃/21℃(T2),and 32℃/26℃(T3).The study examined their impacts on the growth,yield,and quality of ginger roots,stems,leaves,and rhizomes.Results indicated that both growth and growth rates of all ginger organs were highest under T2,lowest under T1,and intermediate under T3.The growth rates of all organs increased with treatment duration.At 10,20,30,40,and 50 days post-treatment,the rhizome growth rates under T2 were 2.05,2.51,3.01,3.88,and 4.99 g·d-1,respectively.By day 50,the fresh rhizome weights for T1,T2,and T3 were 104.79,174.99,and 135.48 g,respectively,with T2 showing increases of 66.99%and 26.16%compared to T1 and T3.The study also found that higher temperatures promoted elongation growth of both aboveground stems and underground rhizomes,but reduced the dry matter,starch,and cellulose content in the rhizomes while increasing soluble sugars,soluble proteins,and free amino acids.As temperatures rose,rhizome ginger oil resin content decreased significantly.
