Identification of water stress-tolerant edible pumpkin seed (Cucurbita pepo) genotypes using seed yield-based tolerance indices

Atilla DURSUN

Pumpkin is usually cultivated in arid and semiarid regions, and the lack of water stress-tolerant cultivars is a major limiting factor. Therefore, this study was carried out to identify superior water stress-tolerant genotypes. For this purpose, 44 inbred lines with superior agronomic traits were selected from the gene pool. In addition, two hybrids (G1-Mert Bey F1 and G2-Sena Hanim F1) and two landraces (G3-Hatun Tırnağı and G4-Cercevelik) with high commercial value were used as commercial cultivars. The water stress indices were calculated from seed yields from the pumpkin genotypes grown in ...Daha fazlası

A review: use of soilless culture techniques in ornamental plants

Atilla DURSUN

The use of soilless culture in the cultivation of ornamental plants is becoming widespread, especially in the production of cut flowers. The aim of this review is to present a brief summary of both standard and new findings obtained from using soilless culture techniques in ornamental plant cultivation, based on a detailed literature review. In the researches reached for this review, Calendula officinalis L., Matthiola incana L., Pelargonium zonale L., Petunia x hybrita L., Pinus pinea, Cupressus arizonica, C. sempervirens, Sternbergia lutea, Galanthus elwesii Hook, Lilium candidum, Limonium s ...Daha fazlası

Improvement of frost tolerance in tomato by foliar application of potassium sulphate

Atilla DURSUN

The study aimed to determine the mean low-temperature exotherms (LTE) of the shoot tip of the dOmur F-1, Cuma F-1, Safir F-1, VT-1770, Elibol F-1, and Adelya F-1 tomato cultivars and Yerli-14 and Yerli-24 local tomato genotypes. Moreover, this investigation intended to specify the most effective dose of potassium sulfate with its efficacy time by applying four different doses of potassium sulfate (K2SO4) foliar fertilizer on the most and least tolerant cultivar. The mean LTE of the shoot tip of seedlings was determined by using differential thermal analysis (DTA). In the second part of the stu ...Daha fazlası

Investigation of genetic diversity of squash (Cucurbita maxima Duchesne) genotypes collected from Erzincan in Turkey

Atilla DURSUN

Plant genetic resources constitute the most valuable assets of countries. It is of great importance to determine the genetic variation among these resources and to use the data in breeding studies. Cucurbita maxima species in the Cucurbitaceae family have high genetic diversity, but molecular genetic diversity studies of this species are insufficient in Turkey. To determine the genetic diversity among genotypes of Cucurbita maxima species of squash, which is widely grown in Erzincan, 14 different squash genotypes collected were examined based on the morphological parameters and molecular chara ...Daha fazlası

Interactive effects of salinity and drought stress on photosynthetic characteristics and physiology of tomato (Lycopersicon esculentum L.) seedlings

Atilla DURSUN

Sufficient quantity and quality of water are essential for vegetable production. Evaluating the individual and combined effects of drought and salt stress on plant establishment may help inform management of plant production in terms of stabilizing yield. This study investigates the effects of drought and salt stress on plant growth, nutrition elements, and select physiological parameters of tomato (Lycopersicon esculentum L. cv. H2274) through a pot experiment under greenhouse conditions. Drought stress was applied to tomato seedlings at 3 different levels of irrigation: D0 (control), D1, an ...Daha fazlası
