摘要:
外源24-表油菜素内酯能够提高弱光下番茄果实产量与品质,缓解弱光胁迫伤害。以弱光敏感型番茄品种‘基尔斯’为试验材料,采用桶式基质栽培方式,研究了外源24-表油菜素内酯对弱光胁迫下番茄植株内源激素含量、碳水化合物代谢、果实产量与品质的影响。结果表明:弱光胁迫显著影响番茄植株叶片内源激素含量及碳水化合物代谢水平、果实产量与品质。弱光下叶面喷施24-表油菜素内酯后,吲哚-3-乙酸、玉米核苷和赤霉素含量分别提高22.8%、3.2%和16.6%;淀粉含量、蔗糖合成酶和蔗糖磷酸合成酶活性分别升高17.9%、18.8%和35.8%;单果质量、单株产量、果实直径、果肉厚度、维生素C含量、可溶性固形物、可溶性糖含量分别升高11.3%、34.7%、11.1%、6.6%、16.4%、11.0%和29.1%,可滴定酸含量降低8.1%,均达到显著水平。表明:外源24-表油菜素内酯能够调控弱光下番茄叶片碳水化合物代谢和内源激素的变化,增强植株的弱光胁迫耐受性,从而提高番茄果实产量和品质。
Abstract:
Exogenous 24-epibrassinolide(EBR)can improve the yield and quality of tomato fruits under low light,and alleviate the low light stress injuries.With low-light sensitive tomato variety‘Jiersi’as the tested material,this research was conducted to investigate the effects of EBR on the endogenous hormone concentration,carbohydrate metabolism in tomato leaves,and yield and quality of tomato fruits under low light stress by substrate culture in bucket.The results showed that endogenous hormone concentration,carbohydrate metabolism capability in tomato leaves,and yield and quality of tomato fruits were significantly changed under low light stress(P<0.05).The indole-3-acetic acid(IAA),corn nucleoside(ZR)and gibberellin(GA3)concentration were significantly increased by 22.8%,3.2% and 16.6%,respectively(P<0.05).The starch concentration,sucrose synthase(SS)and sucrose phosphate synthase(SPS)activities were significantly enhanced by 17.9%,18.8% and 35.8%,respectively(P<0.05).Fruit weight,yield of one plant,fruit diameter,peel thickness,vitamin C,soluble solids,soluble sugar concentration were significantly promoted by 11.3%,34.7%,11.1%,6.6%,16.4%,11.0% and 29.1%,respectively;titratable acid was significantly reduced by 8.1%in the treatment of foliar spraying EBR under low light(P<0.05).It was illustrated that exogenous EBR could regulate the carbohydrate metabolism and endogenous hormone concentration of tomato leaves under low light,afterwards strengthened the low light tolerance of tomato plant,and ultimately improved the yield and quality of tomato fruits.
