Figleaf gourd when to pick up
Therefore, it is concluded that the activity (open/closed state) of aquaporin may be associated with the rate of water uptake and the sensitivity of root systems to low temperature. External application of HgCl2, which is known to inhibit the bulk water transport through aquaporins, also showed an insensitivity of individual figleaf gourd cortical cells as well as entire root system while marked reduction in hydraulic conductivity was observed in cucumber plants. Measurement of half-times of water exchange and hydraulic conductivity of cortical cells with cell pressure probe showed the insensitivity of figleaf gourd cells to low temperature. The different capability in generation of root pressure in two species upon exposure to low temperature was confirmed by measuring the root pressure with excised root system that was related to the activity of plasma membrane H+-ATPase.

Root pressure generated in figleaf gourd during the night under low temperature was able to transport xylem sap but there was little transport in cucumber when measured with heat-balance sap-flow gauge. Low temperature severely reduced xylem sap transport in cucumber but not in figleaf gourd to the same extent. Plants were grown hydroponically and low solution temperature was imposed for different periods. The sensitivity of cucumber and figleaf gourd root system to low temperature was evaluated in terms of water transport capacity. This review summarizes the state of the cucurbit grafting industry on a global level, translating work published in many languages. There have been thorough analyses of cucurbit grafting in other countries, but the literature in English is limited. Some seed companies now offer watermelon transplants grafted onto squash or bottle gourd rootstocks, and some transplant facilities offer grafting services. cucurbit industry sees grafting as an attractive option. Cucurbit grafting is rare in the United States, but with continued loss of quality disease-free farmland along with the phase-out of methyl bromide, the U.S. The type of rootstock affects cucurbit plant growth, yield, and fruit quality. Use of rootstocks can enhance plant vigor through vigorous attainment of soil nutrients, avoidance of soil pathogens and tolerance of low soil temperatures, salinity, and wet-soil conditions. China produces more than half the world's watermelons and cucumbers (Cucumis sativus L.), and approximately 20% of these are grafted. This practice helped control declining yield due to soilborne diseases. Soon after, watermelons were grafted onto bottle gourd rootstocks. It was first commonly used in Japan during the late 1920s by grafting watermelon onto pumpkin rootstocks. In fact, in many parts of the world, grafting is a routine technique in continuous cropping systems. Grafting can overcome many of these problems. Chemical pest control is expensive, not always effective, and can harm the environment. These conditions cause various physiological and pathological disorders leading to severe crop loss. Successive cropping can increase salinity, the incidence of cucurbit pests, and soilborne diseases like fusarium wilt caused by Fusarium spp. These conditions include environments that are too cold, wet, or dry, or are cool low-light winter greenhouses. It is suggested that the tolerance of grafted cucumber to low temperature is enhanced while figleaf gourd as stock is used.ĭue to limited availability of arable land and high market demand for off-season vegetables, cucurbits (plants in the family Cucurbitaceae) are continuously cultivated under unfavorable conditions in some countries. The iPA content in stem of both own-rooted and cucumber/cucumber grafted plants was less than that of cucumber/figleaf gourd grafted plant, while iPA content in leaves of both own-rooted and cucumber/ cucumber grafted plants was higher than that of cucumber/figleaf gourd grafted plant. The iPA distributed with a gradient in stem of both grafted and own-rooted plants, iPA content was the highest in stem apex, followed by upper stem segments, and then lower stem segments. The results showed that Suc, Glc, Pr and CE in cucumber/figleaf gourd grafted plant were higher than those in own-rooted and cucumber/cucumber grafted plants. Contents of sucrose (Suc), glucose (Glc) and soluble protein (Pr) in leaf and content of isopentenyl adenosin (iPA) in stem and leaf were determined respectively, and carboxylation efficiency (CE) was calculated. 4') as ingrafment and cucumber and figleaf gourd (Cucurbita ficifolia Bouché) as stocks, the tolerance of own-rooted and grafted cucumbers to low temperature was evaluated. Using cucumber (Cucumis sativus 'Jinyan No.
