Contents and recovery of gibberellins in monoecious and gynoecious cucumber plants.
Diffusates from seedlings and root exudates from 6-week-old plants of a monoecious line of cucumber, Cucumis sativus L., contained considerably higher levels of gibberellin-(GA-) like substances than did those from plants of an isogenic gynoecious line. Most of the GA-like activity was found in a chromatogram region typical of GA(1) and GA(3); some activity, particularly in root exudates, appea...
متن کاملContents and Recovery of Gibberellins in Monoecious and Gynoecious Cucumber Plants 1
Diffusetes from seedlings and root exudates from 6-week-old plants of a monoecious line of cucumber, Cucumis sativus L., contained considerably higher levels of gibberellin.(GA-)like substances than did those from plants of an isogenic gynoecious line. Most of the GA4ike activity was found in a chromatogram region ty.pical of GA1 and GA3; some activity, particularly in root exudates, appeared a...
متن کاملSex Expression and Level of Phytohormones in Monoecious Cucumber as Affected by Plant Growth Regulators
The hormone levels of auxin and gibberellin were studied in monoecious cucumber plants treated with growth regulators e.g. 2-chloroethylphosphonic acid (ethrel), gibberellic acid (GA3) and maleic hydrazide (MH). The studies were conducted at Vegetable Crops Research Programme, National Agricultural Research Centre Islamabad, Pakistan during 2003 and 2004. The greatest increase in female flower ...

تعداد 20 رأس میش نژاد نائینی 6+-24 ماهه، با میانگین وزن 2/3-+40 کیلوگرم، همراه با 20 رأس بره های آنها در قالب طرح کاملا تصادفی اثر بتائین و مکمل سولفات بر خصوصیات شیر و پشم و عملکرد بره ها بررسی شد. میش ها بطور تصادفی در چهار تیمار قرار گرفتند. تیمارها عبارت بودند از: 1-گروه شاهد 2-بتائین (05/0 درصد ماده خشک) 3-سولفات (24/0 سولفور درصد ماده خشک 4-بتائین هرماه با سولفات. جیره غذائی طبق nrc با مح...
15 صفحه اولSugar signalling is involved in the sex expression response of monoecious cucumber to low temperature.
This study aimed to investigate how low temperature alters the sex expression of monoecious cucumbers (Cucumis sativus L.). Plants were grown under different day/night temperature regimes, 28 °C/18 °C (12 h/12 h), 18 °C/12 °C, 28 °C/12 °C, and 28 °C/(6 h 18 °C+6 h 12 °C). It was found that plant femaleness is highest in the 28 °C/(6 h 18 °C+6 h 12 °C) treatment. Analysis of endogenous phytohorm...
