Abstract

Most of agricultural lands in Iran are located in arid and semi-arid regions and are considered as saline soils. In order to investigate the interaction of salinity as well as potassium and calcium on the growth and yield of tomato plants, a factorial experiment was perfected in the form of randomized complete blocks, in hydroponic conditions, with three replicates per treatment. Experimental factors include salinity at three levels (0, 20, and 40 mM NaCl), potassium content form chloride, nitrate (0 and 15 mM), and calcium from chloride, and nitrate (with 0 and 10 mM) . The studied growth factors, including plant height, stem diameter, number of leaves, flowers and fruits and leaf chlorophyll decreased Received 28.03.2021/ Revised 26.05.2021/ Accepted 27.06.2021/ Published 22.10.2021 :تفایرد 08 / 01 / 1400 / :حلاصا 05 / 03 / 1400 / :شریذپ 06 / 04 / 1400 / :راشتنا 30 / 07 / 1400 [ D O I: 1 0. 52 54 7/ nb r. 8. 3. 20 6 ] [ D O R : 2 0. 10 01 .1 .2 42 36 33 0. 14 00 .8 .3 .5 .8 ] [ D ow nl oa de d fr om n br .k hu .a c. ir o n 20 21 -1 203 ]

不同钾钙来源对水培条件下番茄产量及离子平衡的影响

伊朗的大部分农业用地位于干旱和半干旱地区，被认为是盐碱地。为了研究盐度以及钾和钙对番茄植株生长和产量的相互作用，在水培条件下，以随机完全块的形式完善了析因实验，每个处理重复三次。实验因素包括三个水平的盐度（0、20和40mM NaCl）、氯化物、硝酸盐（0和15mM）中的钾含量、氯化物中的钙以及硝酸盐（具有0和10mM）。所研究的生长因子，包括株高、茎径、叶数、花和果实以及叶片叶绿素下降。收到日期：2021年3月28日/修订日期：2021年5月26日接受日期：202年6月27日发布日期：2014年10月22日：2014年1月8日。52 54 7/nb r.8。3.20 6][日期：2.0。10 01.1.2 42 36 33 0。14 00.8.3.5.8][D ow nl oa de D fr om n br.k hu.a c.ir o n 20 21-1 203]
