不同浓度乙烯利耦合萘乙酸对'温185''新新2号'核桃采收的影响
Effect of Different Concentrations of Ethylene-coupled Naphthaleneacetic Acid on the Harvest of Walnuts of'Wen 185'and'Xinxin 2'
摘要
Abstract
[Objective]To understand the synergistic effect of different concentrations of ethephon(ETH)coupled with naphthaleneacetic acid(NAA)on the harvest of'Wen 185'and'Xinxin 2'walnuts and the optimal concentration combination.[Methods]10-year-old'Wen 185'and'Xinxin 2'were used as experimental materials in this study,and the effects of dif-ferent concentrations of ETH and NAA coupled treatments on the green peel cracking rate,leaf yellowing rate,and fruit quali-ty during the walnut harvest process were systematically investigated.[Results]The synergistic effect of ETH and NAA on leaf yellowing and green peel cracking is concentration-dependent and variety-specific.'Wen 185'had the lowest leaf yellowing rate(≤2.78%)under the E3N2 treatment and maintained a relatively high green peel cracking rate.'Xinxin 2'had a green peel cracking rate of 72.46%and a leaf yellowing rate of only 5.8%under the E2N2 treatment,with a significant increase in kernel yield to 48.55%.Neither treatment had a significant negative impact on fruit size,fat,protein,total sugar,and other quality indicators,and significantly increased the proportion of white kernels and reduced the proportion of yellowish-brown kernels.[Conclusion]The E3N2 treatment was the most effective for'Wen 185'walnuts,and the E2N2 treatment was the most effective for'Xinxin 2'walnuts,both effectively improving fruit quality.关键词
