Abstract Pakistan is the 8th most climate-affected country in globe along with a semi-arid to arid climate, thereby crops require higher irrigation from underground water. Moreover, ~ 70% of pumped groundwater irrigated agriculture brackish and major cause secondary salinization. Cucumber ( Cucumis sativus L.) an important vegetable crop annual growth rate about 3.3% Pakistan. However, it relatively salt-sensitive crop. Therefore, dire need for alternate environment-friendly technology like grafting managing salinity stress cucumber by utilizing indigenous cucurbit landraces. In this regard, non-perforated pot-based study was carried out lath house explore landraces; bottle gourd Lagenaria siceraria ) (cv. Faisalabad Round), pumpkin Cucurbit pepo. L) Local Desi Special), sponge Luffa aegyptiaca Local) ridge acutangula Special) as rootstocks inducing tolerance Yahla F1). Four different salts (NaCl) treatments; T 0 Control (2.4 dSm –1 ), 1 (4 2 (6 3 (8 were applied. The grafted plants transplanted into already-induced pots (12-inch). Different morpho-physio-biochemical, antioxidants, ionic, yield attributes recorded. results illustrate that increasing negatively affected growing plants. showed salt relative non-grafted ones. Indigenous landrace Round) exhibited compared due up-regulation also confirmed principal component analysis (PCA). Shoot root biomass, chlorophylls contents (a b), activities superoxide dismutase (SOD), catalase (CAT) peroxidase (POX) enzymes, antioxidants scavenging activity (ASA), ionic (↑ K Ca, ↓ Na), yield-related found maximum onto landrace. Hence, ‘cv. round’ may be utilized rootstock under mild saline environment. further evaluated moderate field conditions possible developing hybrid and, subsequently, sustainable production.

Physiological and Germination Responses of Muskmelon (Cucumis melo L.) Seeds to Varying Osmotic Potentials and Cardinal Temperatures via a Hydrothermal Time Model

ACS Omega, Journal Year: 2023, Volume and Issue: 8(37), P. 33266 - 33279

Published: Sept. 7, 2023

Climatic changes have a direct negative impact on the growth, development, and productivity of crops. The water potential (ψ) temperature (T) are important limiting factors that influence rate seed germination growth indices. To examine how responds to in temperature, hydrotime model hydrothermal (HTT) been employed. HTT calculates concept time across temperatures, between Tb-To, with alteration, Tb-Tc, supra-optimal ranges. seeds Cucumis melo L. were germinated laboratory for hydro-thermal experiment. Seeds sown Petri dishes containing double-layered filter paper at different osmotic potentials (0, -0.2, -0.4, -0.6, -0.8 MPa) by providing PEG 6000 (drought stress enhancer) temperatures (15, 20, 25, 30, 35 °C). controlled replicate was treated 10 mL distilled rest solution. Results indicated vigor index (SVI-II) highest 15 °C 0 MPa lowest 30 -0.2 MPa. However, activity shown catalase (CAT) guaiacol peroxidase (GPX) (-0.6 MPa), while values CAT GPX recorded control °C, respectively. Germination energy positively correlated (GI), percentage (G%), index, index-I (SVI-I), mean moisture content (MMC), root shoot ratio (RSR) had correlation rate, percent root, CAT, superoxide dismutase, ascorbate peroxidase, GPX. In conclusion, thermal models correctly predicted muskmelon response varying temperature. agronomic attributes found be maximum minimum °C.

Morphoanatomical and Physiological Adaptations of Triticum aestivum L. against Allelopathic Extract of Trianthema portulacastrum L. (Horse purslane)

ACS Omega, Journal Year: 2023, Volume and Issue: 8(39), P. 35874 - 35883

Published: Sept. 21, 2023

Weed infestation can be harmful to crop growth and cause severe losses in yield by absorbing nutrients releasing inhibitory secondary metabolites thus needs controlled for food security. The use of synthetic herbicides is one the most widely applied methods, but its frequent usage a serious threat health environment develops resistance weeds. Allelopathy an eco-friendly bio-control method, Trianthema portulacastrum extracts are known effective against various weeds Triticum aestivum (wheat), their effect on main (wheat) still unknown. pot experiment was carried out, concentrations (30, 60, 100%) root shoot T. herbicide (Metafin Super) along with control (distilled water) were wheat plants. Various morphological, physiological, anatomical parameters recorded under natural conditions. objective this study explore allelopathic impact compared wheat. This displayed that characteristics significantly affected at p ≤ 0.05 water less as herbicide. inhibition coupled significant increase total free amino acids, K ions, CAT (catalase), proline, epidermal cortical thickness, abaxial stomatal density. In addition, reduction correlated decrease photosynthetic pigments. revealed could safer than plants would beneficial field.
