The effect of different pruning methods on the storage substances of upland cotton seeds
摘要
Abstract
[Objective]This research aimed to investigate the effects of different pruning methods on the content of storage substances in upland cottonseed.[Methods]A field trial was conducted in Kashgar Prefecture,Xinjiang,in 2023,using a split-plot design.The main plots consisted of two cotton varieties(J8031 and Yuanmian 8),while the subplots involved different pruning treatments:retaining 3,5,7,or 9 bolls per plant from the flowering and boll-setting stage to harvest(T1,T2,T3,and T4 treatments);removing vegetative branches during the budding stage(T5);removing axillary buds during the flowering and boll-setting stage(T6);removing vegetative branches from the initial flowering stage to the flowering and boll-setting stage(T7);removing empty branches during the late flowering stage and early boll-opening stage(T8);and topping during the full flowering stage to boll opening stage(T9).No pruning was used as the control treatment(CK).The contents of total protein,19 amino acids,total fat,25 fatty acids,and gossypol in cottonseeds were measured under different treatments.[Results]Under T1 to T9 treatments,the total protein and total fat contents in cottonseed of J8031 and Yuanmian 8 showed no significant difference compared with CK.Compared with CK,T5 treatment significantly increased the contents of phenylalanine,arginine,tyrosine,proline,and glycine in J8031,as well as the contents of methionine,phenylalanine,arginine,tyrosine,proline,cysteine,and hydroxyproline in Yuanmian 8,significantly reduced the content of methionine in J8031.T6 treatment significantly increased arginine,tyrosine,and serine contents in J8031,as well as phenylalanine,tyrosine,and hydroxyproline contents in Yuanmian 8,significantly reduced methionine content in J8031.Compared with CK,the contents of stearic acid,heneicosanoic acid,and linoleic acid in J8031,and the contents of palmitic acid and eicosadienoic acid in Yuanmian 8 all significantly increased under T2 treatment.The contents of myristic acid,arachidic acid,eicosapentaenoic acid,and oleic acid in J8031 under T7 and T9 treatments significantly decreased.Under T1 treatment,the contents of palmitic acid,hexanoic acid,eicosapentaenoic acid,and eicosenoic acid significantly increased in Yuanmian 8;while the oleic acid content in J8031 and Yuanmian 8 significantly decreased.Under T7 and T8 treatments,the contents of heneicosanoic acid,linoleic acid,palmitoleic acid,oleic acid,and eicosenoic acid in Yuanmian 8 significantly decreased.Under T3,T5,T7,T8,and T9 treatments,both total(-)/(+)-gossypol and free(-)/(+)-gossypol contents in J8031 were significantly higher than that in CK.Compared with CK,total(-)/(+)-gossypol content in Yuanmian 8 significantly increased under T8 treatment,while free(-)/(+)-gossypol content significantly decreased under the nine treatments from T1 to T9.[Conclusion]Compared with CK,pruning treatment had no significant effect on the total protein and total fat contents in cottonseed of J8031 and Yuanmian 8,but significantly influenced the contents of certain amino acids,certain fatty acids,and gossypol.关键词
