Abstract:

 We aimed to investigate the effects of some seed priming and foliar applications on stress prevention in cotton under deficit irrigation conditions. Seed priming with mepiquat chloride PIX and foliar applications of salicylic acid SA and proline PRO were tested at three levels of irrigation at 25, 50, and 100 of field capacity. Plant height, boll number, fiber length and fiber strength were significantly affected by the interaction of irrigation level  treatment. The effects of irrigation level and treatment were significant for boll weight, seed index, seed cotton yield and lint yield. When deficit irrigation conditions 25 were compared with full irrigation, plant height decreased by 21.6 , boll number by 18.1 , boll weight by 26.0, seed index by 5.8, seed cotton yield by 25.6 and lint yield by 24.6. Seed priming with PIX and foliar application of PRO produced significantly higher seed cotton and lint yields, whereas SA application had favourable fiber quality parameters under deficit irrigation conditions. PRO slightly increased fiber fineness. Foliar application of SA positively affected chlorophyll content SPAD and leaf area index LAI under deficit irrigation. In conclusion, it was recommended that all three practices could be successfully used to alleviate negative impacts under deficit irrigation conditions.

 Pamukta su kısıntısı koşullarında bazı tohum ön uygulaması ve yaprak uygulamalarının stresi önleme üzerine etkilerinin araştırılması amaçlanmıştır. Mepiquat klorid PİX ile tohum ön uygulaması ve salisilik asit SA ile prolinin PRO yaprak uygulamaları tarla kapasitesine göre düzenlenen 100, 50 ve 25 sulama konularında test edildi. Bitki boyu, koza sayısı, lif uzunluğu ve lif dayanıklılığı özellikleri sulama seviyesi  uygulama etkileşiminden önemli ölçüde etkilenmiştir. Koza ağırlığı, tohum indeksi, kütlü pamuk verimi ve lif verimi için sulama düzeyi ve uygulamanın etkileri önemliydi. Kısıntılı sulama koşulları 25 tam sulama ile karşılaştırıldığında, bitki boyu 21,6, koza sayısı 18,1, koza ağırlığı 26,0, tohum indeksi 5,8, kütlü pamuk verimi 25,6 ve lif verimi 24,6 oranında azalmıştır. PİX ile tohum ön uygulama ve PROnun yapraktan uygulanması önemli ölçüde daha yüksek kütlü pamuk ve lif verimi sağlarken, SA uygulaması kısıntılı sulama koşulları altında yüksek lif kalitesi parametrelerine sahip olmuştur. PROnun lif inceliğini az da olsa artırdığı tespit edilmiştir. SAnın yapraktan uygulanması, kısıntılı sulama koşullarında klorofil içeriğini SPAD ve yaprak alan indeksini LAI olumlu yönde etkilemiştir. Sonuç olarak, her üç uygulamanın da kısıntılı sulama koşullarında olumsuz etkileri hafifletmek için başarıyla kullanılabileceği önerilmiştir.
