“…The Pb 2+ has a lower hydrated radius (401 pm) than Zn 2+ (430 pm) and Cu 2+ (419 pm) (Nightingale, 1959), which increases Pb retention in the plant. In a study carried out in Arachis hypogaea L. cultivars, changes in Zn and Cu contents showed similar results (Nareshkumar et al, 2014). No significant difference in Mn content of switchgrass was observed in varying Pb doses.…”

Madencilik, kentsel veya endüstriyel katı, gaz ve sıvı atıklar, pestisit ve suni gübre kullanımı, boya sanayi ve araba egzoz gazları ağır metallerin doğaya salınmasına neden olur. Çevresel kirleticilerin neden olduğu bu ağır metal stresi, bitkilerin büyümesini sınırlamakta, ürün verimini ve kalitesini düşürmektedir. Aynı zamanda, ağır metal stresi bitki besin maddelerinin bitkiler tarafından alınmasını, taşınmasını ve kullanılmasını engeller. Sonuç olarak, bu çalışma, geniş bir habitat ve iklim yelpazesine uyum sağlayabilen switchgrass’taki kurşun, kadmiyum ve kromun toksisitesini ve toleransını değerlendirmek için yapılmıştır. Ağır metallerin besin alımı üzerindeki etkilerini belirlemek amacıyla, Switchgrass (Panicum virgatum L.) bitkisi farklı konsantrasyonlarda Cd, Pb, Cr çözeltileri ile suni olarak kontamine edilmiş toprakta yetiştirilmiştir. Uygulanan metallerin farklı konsantrasyonlarından etkilenen switchgrasstaki makro ve mikro besin içeriklerindeki değişiklikler değerlendirilmiştir. Krom, kadmiyum ve kurşun fitotoksik etkiye sahip ve bitkiler için esansiyel olmayan elementler olmalarına rağmen, bu elementlerin switchgrass bitkisinin toprak üstü kısımlarında kolayca emilip biriktiği gözlenmiştir. Genel olarak, switchgrass bitkisindeki makro ve mikro besin konsantrasyonlarının farklı dozlarda Pb, Cd ve Cr uygulamalarında önemli ölçüde veya nispeten azaldığı bulunmuştur. Ca2+ ve Pb2+'nın kök hücrelere giriş için rekabet etmesi nedeniyle, uygulanan farklı Pb dozları ile sadece bitkideki Ca konsantrasyonları önemli ölçüde artmıştır. Bununla birlikte elde edilen sonuçlar lineer regresyon ve Pearson korelasyonu kullanılarak yorumlanmıştır.

“…The cooking of different seeds was carried out with and without presoaking step for different time periods. After cooking, samples were tested for their softness as per the method given by Singh et al (1991). The time required to obtain hundred per cent cooked seeds was recorded as the cooking time.…”

Background: From ancient times, lentil has been a prominent part of our diet. Nowadays, there is an emerging interest in lentil, as it is a potential food of plant origin having ample amount of nutrients, which contributes to numerous health benefits. Methods: The seeds of lentil (PL 8) were screened for visual impurity and deformity and sound seeds were selected for further analysis. The seeds were subjected to milling and the flour obtained was further used to analyze the physical parameters, nutritional quality, antinutrient content and cooking characteristics of the chosen variety. The impact of soaking on cooking quality was also observed. Result: It was observed that lentil (PL 8) seeds had higher content of protein, dietary fibre and anti oxidants. However, the antinutrient content as well as physical properties were comparable with the other varieties studied by various authors. It was further observed that soaking of seeds prior to cooking reduced cooking time.

“…The Pb toxicity causes a decrease in the percentage of seed germination (Shafiq et al, 2008), plant growth and yield (Kumar & Jayaraman, 2014), nutrient and mineral disturbances (Lamhamdi et al, 2013;and Nareshkumar et al, 2014), inhibits photosynthesis (Tian et al, 2014), enzyme activity (Malar et al, 2016), as well as causes imbalance and changes in membrane permeability (Sharma & Dubey, 2005;Israr & Sahi, 2008). It is important to note that germination and root growth are the stages of plant development considered to be very sensitive to the contamination of this element.…”

This research aimed to determine the effect of different concentrations of Lead (Pb) on the morphology of kale and spinach plants. The process involved planting kale and spinach seeds in tubs and transferring them to polybags with planting media in the form of soil and sand at a ratio of 4:1 after strong roots were developed. It is important to note that the media were analyzed to ensure the Pb content in the soil was below the threshold before planting. Pb was later provided 1 week before planting in the form of PbNO 3 in the media at a dose of 1 and 2 g/polybag and mixed effectively to ensure even distribution, while the sample used as the control was not given any Pb. The transplanting process was conducted after the plants were 18 days old in the nursery and the initial observations at 9 DAT showed that the kale leaves were darker with a score of 3 than spinach with a score of 1, but the spinach leaves became darker in color with score 3 as the age of the plants increased. Moreover, the kale changed to a lighter color with a score of 2 from the 9 th day of observation after transplanting, while spinach requires 15 DAT to become score 2 until the end of the observation. It should be pointed out that both plants showed morphological changes due to the existence of the Pb but their base leaves did not reflect any effect. The kale leaf tip became blunt, while the spinach leaf tip was not affected and both plants were discovered to have longer roots and more root hairs in the control compared to the treatments. Furthermore, the total chlorophyll of spinach in the control was higher than kale but observed to reduce as the concentration of Pb increased in the treatments. The morphology and physiology of spinach and kale plants changed due to the Pb exposure with the spinach was discovered to be more sensitive as indicated by more visible morphological damage to its leaves at the end of the observation. It is possible to use the morphology of spinach and kale to detect Pb-contaminated land.
