While it is conceivable that an excess of bases in the cell solution might be protective against mild sulfur burn, this possibility has not yet been tested. On the other hand, a small increase in buffer capacity might reduce sulfur burn. An example of this effect may be seen in the buffer curves of the leaf sap in two of the United States Department of Agriculture s muskmelon varieties. No. 5, which is susceptible to sulfur burn, has a buffer curve which lies 0.2 to 0.3 pH unit closer to the acid side than the buffer curve of the sulfur burn-resistant variety, No. 11353 (Figure 1).

The authors wish to express their appreciation for the grants-in-aid made by the Texas Gulf Sulphur Company in the early stages of this work, without which it could not have been undertaken. The authors are also indebted to J. T. Middleton for the samples of muskmelon leaves. The radioactive sulfur 35 as H2S 04 was obtained from the Atomic Energy Commission, Oak Ridge, Tenn., and subsequently processed by Tracerlab, Boston, Mass.

The aroma volatiles of some melon species consist of a complex mixture of esters together with other components, including C9 unsaturated aldehydes, alcohols, and acetates whose sensory properties have been described as melonlike [10,31-33,35]. Several esters and alcohols were described among the volatiles of muskmelons [33, 34].

The function of these tomatinase in formae speciales that do not pathogenise tomato is unknown. One possible explanation could be the presence of tomatine or similar saponins in their host plant species. However, (i) tomatine has not yet been reported in these plants [2, 7, 9] and (ii) although some of these species contain small amount of tomatine and other saponins structurally related to tomatine (e.g. potato contains a- solanine and a-chaconine [2, 4, 9, 90]), these are inactive as inducers of tomatinase and, moreover, tomatinase cannot use any of these glycoalkaloids as substrate [89]. In addition, it is clear that tomatinase is not required for pathogenicity in these isolates, at least in the case of F. oxysporum f. sp. melonis, where some strains that are fully pathogens on muskmelon lack tomatinase activity [89].

Cantaloupe is a name commonly used for muskmelons in the United States. See the Melon entry beginning on page 148 for culture and pest information. Harvest when fruit smells ripe and the stem separates easily from the vine. 

Yellow spots that turn brown are caused by anthracnose. Infected leaves eventually die. This disease causes fruit with circular black cankers. Prevent problems by planting anthracnose-resistant muskmelon cultivars, such as Passport , and resistant watermelon cultivars, such as All Sweet , Crimson Sweet , Dixie Lee , and Sweet Favorite . 

Fruit flesh not sweet. Causes Premature harvest overwatering nitrogen deficiency. Harvest muskmelons and honeydews when they smell ripe and the stem separates easily from the vine when the fruit is gently lifted. Harvest watermelons when the bottom of the fruit turns from pale yellow to golden yellow. Excess rain or irrigation while fruit is swelling... 

The photosynthetic efficiency mainly depends on the openness of stomata, particularly in C3 crops, while their closure tends to avoid excessive water loss. Abscisic acid (ABA) mediates water loss from the guardian cells of the stomata, which is triggered by a decrease in the water content of the leaf and inhibits leaf expansion. In muskmelon seedlings, ABA could improve the maintenance of the leaf water potential and relative water content, and reduce electrolyte leakage [55].

The taste of the muskmelon is very sweet creamy with a strong, sweet, floral fruity-sulphurous and typical melon-like, fatty, green aroma. The taste of watermelon is very watery, juicy, sweet with a weak green, fatty, cucumber-like aroma. 

CIC In both melon types the lipid degradation products (Z)-6-nonenol, (Z,Z)-3,6-nonadienol and the corresponding aldehydes are responsible for the typical green, fatty, cucumber melon aspect. Ethyl propionate imparts an overripe character to muskmelon flavour, supported by the sweet, caramelic aspect of 2-methyl-5-ethyl-4-hydroxy-furan-3(2H)-one and the fmity-sulphurous aroma of S-methyl thioacetate and methyl thiobutyrate.
